We consider uplink sparse code multiple access (SCMA) systems associated with multiple input multiple output (MIMO), where the transmitters and the receiver are equipped with multiple antennas, for enhanced reliability (diversity gain) or improved data rate (multiplexing gain). For each diversity or multiplexing based MIMO scheme combined with SCMA, we develop low-complexity iterative detection algorithms based on the message passing algorithm (MPA) and the expectation propagation algorithm (EPA). We show that the MIMO-SCMA under EPA enjoys the salient advantage of linear complexity (in comparison to the MPA counterpart with exponential complexity) as well as enhanced error rate performances due to the MIMO transmission. We also show that the performance of EPA depends on the codebook size and the number of antennas.

CPS (Cyber-Physical Systems) is proposed by the NSF (National Scientific Foundation) to describe a type of necessities which conglomerates hardware and software components and being the next step in development of embedded systems. CPS includes a wide range of research topics from signal processing to data analysis. This paper contains a brief review of the basic infrastructure for CPS including smart objects and network aspects in relation to TCP/IP stack. As CPS reflect the processes of the physical environment onto the cyber space, virtualisation as important tool for abstraction plays crucial role in CPS. In this context paper presents the challenges associated with mobility and vritualisation; accordingly, three main types of virtualisation, namely network, devices and applications virtualisation are presented in the paper. The main focus of the paper is made on security. Different threats, attack types and possible consequences are discussed as well as analysis of various approaches to cope with existing threats is introduced. Furthermore, needs and requirements for safety-critical CPS are reviewed.

In this paper, an $8times 8$ Multiple Input Multiple Output (MIMO) antenna design for Fifth Generation (5G) sub-6GHz smartphone applications is presented. The antenna elements are based off a folded quarter wavelength monopole that operate at 3.4-3.8GHz. Isolation between antenna elements is provided through physical distancing. The fabricated antenna prototype outer casing is made from Rogers R04003C with dimensions based on future 5G enabled phones. Measured results show an operating bandwidth of 3.32 to 3. $925mathrm{G}mathrm{H}mathrm{z}(mathrm{S}_{11}lt$ -6dB) with a transmission coefficient $lt_{-}14.7mathrm{d}mathrm{B}$. A high total efficiency for an antenna array is also obtained at 70-85.6%. The design is suitable for MIMO communications exhibited by an Envelope Correlation Coefficient (ECC) $lt0.014$. To conclude a Specific Absorption Rate (SAR) model has been constructed and presented showing the user’s effects on the antenna’s S-parameter results. Measurements of the amount of power absorbed by the head and hand during operation have also been simulated.

In this study, we build an integrated microscope with multi-spectrum polarization imaging (MSPI) technology. Polarization imaging is achieved by rotating the polarizer and quarter wave plate, which can obtain parametric images of Stokes parameters, the polarization phase retardance, and the polarization ellipticity orientation angle. Hyperspectral imaging is achieved by using an electronically controlled liquid crystal wavelength filter in front of the broad-band visible light source. By calculating and integrating the intensity and parametric images under different illumination spectrum, the limitation of current polarization imaging due to the wavelength-dependent absorption of the sample was avoided. A significant improvement in resolving power and contrast was found in the imaging results of oocyte cells.

Ultra-Reliable and Low Latency Communications (URLLC) is one of the most important service classes of the emerging 5G and beyond communications systems. This service is used for various applications including medical and healthcare, industrial automation, transportation and robotics where both latency and reliability is of paramount importance. To ensure very low latency, most widely used method is to use short packet size. For ensuring latency and reliability requirement, designing efficient scheduling mechanism is a major challenge. In this work, we propose an efficient packet scheduling algorithm for downlink data transmission. The algorithm provides the highest priority to the packets with largest weighted delay based quantity. The performance of the algorithm is evaluated against some key performance metrics and compared with existing well known scheduling scheme such as proportional fair (PF) and exponential proportional fair (EPF) schemes. The results show the superiority of the proposed packet scheduling algorithm compared to the above mentioned existing schemes.

The emergence of generative adversarial network (GAN) promotes the great progress of deep learning generation model. In this paper, generative adversarial network is used to remove the visual artifact of compressed video, and a visual perception enhancement algorithm for HEVC compressed video is proposed. Specifically, after HEVC compression, the reconstructed image is output by GAN generator. The output image can effectively guide the discriminator of GAN to approximate the mapping between the encoded frame and the original frame. The adversarial loss of the generator to keep learning this mapping, which not only improves the visual perception quality of compressed video, but also removes the artifact. Experimental results demonstrate the superiority of our GAN network over other methods in terms of both Perceptual Index and visual quality.

The mobile crowd sensing (MCS) network is a new reliable and robust paradigm It consists of the Internet of Things (IoTs), wireless sensor networks (WSNs), and mobile personal devices. MCS is commonly used for social, infrastructural, and environmental data collection. Therefore, MCS architecture is utilized for a real-time traffic flow measurement and for predicting the quickest path. Nowadays, traffic congestion is becoming a severe concern in urban areas. The main reasons for traffic congestion and traffic jam on the roads of metropolitan cities are ever-increasing population and vehicle production. Therefore, in this paper, we propose an MCS system, which provides the user congestion-free path to reach the destination in minimum travel time. The MCS architecture exploits collected smartphone data (e.g., speed, direction, and location) for a real-time traffic prediction. Subsequently, K-means Clustering is used to divide the traffic into small clusters. Then the convex hull algorithm is used to calculate the weights of each cluster. In this manner, the proposed system can competently determine the quickest path. The MCS system updates the user about the real-time traffic flow and suggests the quickest path after a specific interval of time until the user reaches the destination. We evaluate the proposed system by comparison with the traditional systems. The obtained results demonstrate that the proposed system provides less distance and reduces the travel time for different traffic scenarios as compared to traditional systems.

In this paper we propose a compact size rectangular implantable tri-band patch antenna for biotelemetry applications. Rogers RT6010 is used as substrate and superstrate material. The resonant frequency is further lowered by using a shorting pin which also reduces patch resistance. For excitation 50-ohm microstrip line is used. The antenna operates in MICS band (402405) MHz, ISM band (902-928) MHz and (2.4-2.48) GHz at 402 MHz, 915 MHz and 2.4 GHz. The gain of the antenna is 2.05 dBi, 2.67 dBi and 5.39 dBi with bandwidth of 120 MHz, 166 MHz and 190 MHz at relevant frequencies when simulated in a fat layer box. SAR values are within allowable limits. The simulated results show that the antenna is an excellent choice for implantable applications as it can be used for data transmission, wakeup signal and wireless power transfer by using three frequency bands.

This paper studies the application of wideband frequency-modulated continuous-wave (FMCW) radar where the received signals are sampled first before processing. It is shown that sampling at a rate of the same order as the transmitted signal bandwidth and reducing the processed fast-time interval, helps resolve the effect of some unwanted artifacts accompanied with increasing the bandwidth and the target’s radial velocity. A signal model is first developed to capture range and velocity parameters, and upper bounds are then defined on the bandwidth that separate the wideband scenario from the narrowband one; finally a novel two-stage multiple signal classification (MUSIC) based algorithm is proposed and simulation results are provided to demonstrate its performance.
