High-quality and low-latency communication in the three major application scenarios of 5G mobile communication technology is a guide for future technological development. The Industrial Internet needs to deal with the data transmission tasks of large-traffic mobile bandwidth and ultra-low latency. Orthogonal Frequency Division Multiplexing/Offset Quadrature Amplitude Modulation (OFDM/OQAM) passive optical network (PON) systems are affected by inherent imaginary interference (IMI), part of which is generated by the chromatic dispersion (CD) of optical fiber systems. Another part is produced by polarization mode dispersion (PMD). This paper proposes a channel estimation (CE) algorithm based on compressed sensing (CS), where the signal exhibits sparsity through sparse representation, and the signal reconstruction algorithm of compressed sensing adopts the orthogonal matching pursuit algorithm (OMP). The channel transfer function (TF) can effectively reduce the IMI and make the signal accuracy of the receiving end higher. Simulation results show that CS-CE algorithm can improve the system performance, which is better than the traditional LS method. Compared to existing LS methods, the CS algorithm can accomplish a 20% improvement. The algorithm can reduce the bit error rate of the system and improve the reliability of the system.

We consider a visible light communication (VLC) system using a digital signage and an image sensor. In order not to impair the visual quality of the background image of digital signage, modulation is performed by changing its color components by taking advantage of the fact that changes in specific color components are difficult for the human eyes to perceive. In previous studies, modulation was based on only one color component, and the communication quality depended on what background image was used. In this study, we propose a modulation method in which the background image does not affect the communication quality by multiplexing the modulation with two color components and applying diversity demodulation. The proposed method is evaluated by a trade-off evaluation of communication quality and quantitative visual quality, and shows the best result regardless of the background image. In addition, the visual quality is improved by using uniform color space that provides uniform color changes for the human eyes.

The satellite backhaul is becoming a feasible solution to connect a large set of Internet of Things (IoT) devices, deployed in a remote, and not-easily accessible area where no cost-effective terrestrial network is available. While several simulator and emulator tools have been designed for terrestrial and satellite networks, there is a lack of tools reproducing both together. In this paper, we focus on the LoRaWAN network with satellite backhaul, and we design an emulation-based testbed that implements the entire end-to-end system by integrating emulated satellite components, with real LoRaWAN devices. The testbed allows running experiments in real working conditions, considering the impact of Hardware and Software components, and environmental factors impacting the reliability of the satel-lite channel. First experiments have confirmed the feasibility of a Geostationary Earth Orbit (GEO) satellite backhaul for a LoRaWAN network. The delay introduced by the satellite does not heavily impact the normal protocol behaviour. On the contrary, attenuation on the satellite channel (due to not clear sky condition) may hinder the Over The Air Activation (OTAA) join procedure, and the reception of Acknowledgment (ACK) by Class-A devices. In ideal condition (clear sky) the achieved performance in terms of Packet Delivery Ratio (PDR) is comparable to the ones obtained with an Ethernet-based terrestrial backhaul.

An M-point combinatory (MC) modulation is proposed for parallel transmission (PT) image sensor (IS)-based visible light communication (VLC). In the conventional PT system, $M_{0}$ discrete signals which incorporate $N=(M_{0}-1)/2$ spatial frequencies are transmitted in parallel with $M_{0}$ transmitting regions of liquid crystal display (LCD). When each of spatial frequencies is modulated with P-ary phase shift keying (P- PSK), the number of bits transmitted in one frame is given by $k=Nlog_{2}P$ bits. $k$ increases when the number of spatial frequencies $N$ increases with increasing $M_{0}$, but at same time, the peak-to-average power ratio (PAPR) becomes high because the signal of the PT system is essentially orthogonal frequency modulation. Therefore, the number of spatial frequencies $N$ without any error remains at a very low number. In this paper, we propose an MC modulation, which is combined with the PT system to increase the number of bits per frame that the system carries without any error. In our proposed MC PT system, $M$ out of the $M_{0}$ transmitting regions are used, where $Mleq M_{0}$. Since there are $left(begin{array}{c}M_{0} Mend{array}right)$ ways in choosing $M$ out of the $M_{0}$ ones, we map them to $ell=leftlfloorlog _{2}left(begin{array}{c}M_{0} Mend{array}right)rightrfloor$ bits. According to $ell$ bits, $M$ transmitting regions are chosen for a frame, and then the $M$ chosen ones are used to transmit $M$ discrete signals of the PT system. Our experimental results show that our proposed MC PT system with 8-PSK achieves 697 bits/frame with keeping no error being observed, while the conventional PT system achieves only 180 bits/frame.

One of the critical challenges of operating with the terahertz or millimeter-wave wireless networks is the necessity of at least a strong non-line-of-sight (NLoS) reflected path to form a stable link. Recent studies have shown that an economical way of enhancing/improving these NLoS links is by using passive metal-lic reflectors that provide strong reflections. However, despite its inherent radio advantage, metals can dramatically influence the landscape's appearance - especially the indoor environment. A conceptual view of escaping this is by using transparent reflectors. In this work, for the very first time, we evaluate the wireless propagation characteristics of passive transparent reflectors in an indoor environment at 28 GHz, 39 GHz, 120 GHz, and 144 GHz bands. In particular, we investigate the penetration loss and the reflection characteristics at different frequencies and compare them against the other common indoor materials such as ceiling tile, clear glass, drywall, plywood, and metal. The measurement results suggest that the transparent reflector, apart from an obvious advantage of transparency, has a higher penetration loss than the common indoor materials (excluding metal) and performs similarly to metal in terms of reflection. Our experimental results directly translate to better reflection performance and preserving the radio waves within the environ-ment than common indoor materials, with potential applications in controlled wireless communication.

5G Non-Public-Network (NPN) is increasingly ap-plied in the vertical industry, and there are still several related functionality and deployment requirements need to be solved. In this paper, we present a testbed of our proposed blockchain-enabled NPN architecture for the functionality requirements along with an NPN construction scheme based on cloud and containerization technique to meet the deployment demand. Blockchain's openness and transparency can provide a trusted data sharing environment for different NPN stakeholders, and its smart contract can implement flexible and customized access control policies. Meanwhile, the use of containerization and cloud technology enables the rapid deployment, upgrade and migration of NPN, reducing the costs of network construction and maintenance. Some typical test cases and initial results are shown to indicate that our blockchain-based testbed can not only be a candidate solution for mobile communication researches but also for commercial and industrial purposes.

The evolution of cellular fifth-generation (5G) tech-nologies shapes the future of the manufacturing industry by enabling sector automation and digitalization. Smart factories rely primarily on wireless connectivity provided by new radio (NR) systems to meet the stringent requirements of industrial applications. Among these, several industrial wearable and sensor-based services involve devices with relaxed communication capabilities as compared to Rel-15 NR user equipment. Hence, a new category of reduced-capability (RedCap) devices becomes essential in industrial private networks. As RedCap devices may experience degradation of uplink (UL) performance due to simplifications in radio frequency and baseband capabilities, this paper focuses on enhancing NR RedCap operations with existing 5G solutions for UL improvement, namely, dual connectivity, carrier aggregation, and supplementary UL. Specifically, we discuss these options for RedCap wearable devices and evaluate the performance gains of the selected technology using link-level simulations.

We propose new game theoretic frameworks that permit to maximize the performance of an interference-limited photon-counting multiuser Poisson channel with asymptotically low transmit power considered. For a memoryless stationary Poisson channel, we consider a conflicting situation where multiple users share the same spectrum and attempt to maximize their throughput. The system model is constructed, where multiple transmitters communicate with many users each equipped with a single photon-counting receiver. Importantly, to limit the interference, we consider the transmission at an asymptotically low-power regime. The first contribution of this paper is to model the problem as a non-cooperative game and present the Nash equilibrium beamformer. We present the sufficient and necessary conditions for the Nash equilibrium solution. Next, we develop a cooperative game, where users can autonomously bargain to maximize their achievable capacity. To obtain the Nash bargaining solution, we generate the convex hull by performing time sharing. The key idea utilized in generating a convex hull is to choose different strategies at different time slots. The bargaining among the users is shown to yield a significant performance improvement at asymptotically low transmit power. Moreover, it is shown that selfish but cooperative users can achieve maximum sum-rate performance.

Wireless communication technology, partic-ularly in Unmanned Aerial Vehicle (UAV) applications, has advanced rapidly recently. However, owing to se-curity flaws, UAV-based applications have not reached their full potential. Interception of drone-based station communication is possible. Many authentication mechanisms, including Physical Unclonable Functions (PUF) based protocols, have been developed to address this problem. However, prior studies require noise-resistant and theoretically perfect PUF. This assumption restricts the usage of UAV-based authentication. This assumption limits the use-cases for UAV-based authentication systems. So we propose a novel distributed authentication approach based on Shamir's secret sharing that is resistant to noisy PUFs.

Recently, reconfigurable intelligent surface (RIS) rises as one of the potential key technologies for the next generation of wireless communications. RIS consists of a large array of planar elements, each of which can be configured individually to induce additional phase shifts to the impinging signals. Therefore, the wireless propagation can be handled in a smart manner by reconfiguring the RIS. In this article, we demonstrate an RIS-assisted simultaneous wireless information and power transfer (SWIPT) system for the Internet of Things (IoT) devices. The experiment results of the RIS-assisted SWIPT system show promising gains in the wireless transmission quality over the SWIPT system without RIS deployment.
