Cloud Radio Access Network (CRAN) is a promising network architecture for 5G to address the increasing demand for mobile data traffic. We consider a joint beamforming and clustering (user-to-Remote Radio Head (RRH) association) issue for downlink CRAN to solve the sum-rate maximization problem under fronthaul link capacity and per-RRH power constraints. The main objective is to investigate and analyze the trade-off between system throughput and the incurred costs in terms of complexity and signaling overhead, including the impact of imperfect Channel State Information (CSI). We propose a hybrid algorithm which periodically activates dynamic and static clustering strategies to manage the allocation process over time. This algorithm has the benefit to approach the optimal performance while being aware of practical system constraints. Furthermore, we present an analysis of major cost metrics for the proposed and reference dynamic algorithms. The simulation results show that our proposed algorithm reduces significantly the complexity and signaling costs while approaching the performance of the optimal solution.

This paper experimentally investigates the use of a single input multiple output (SIMO) free space optical (FSO) communication system in an indoor laboratory controlled turbulence chamber. Two receiver circuits are used with a single laser input. The current outputs of two receivers were combined using equal gain combining (EGC) scheme and compared with single input single output (SISO) FSO system. A weak turbulence was generated within the atmospheric chamber and link performances are measured using ß-factor and bit error rate (BER) for On-Off Keying (OOK) modulation scheme. The results demonstrated that the simplest form of SIMO can improve the performance of the FSO communication channel under weak turbulent condition.

The tremendous increase of mobile data traffic pushes operators to find quick and efficient solutions in order to avoid an overload on their networks. Using WiFi to offload a part of the traffic is interesting for the operators as they can take advantage of the unlicensed bands and high bit rates. Moreover, thanks to the convergence of fixed and cellular networks, it is possible to connect WiFi access points to the LTE eNodeBs in order to have Very Tight Coupling between LTE and WiFi. Thus, the different flows are merged at the link layer (i.e. PDCP) and share the same IP instance. This allows the terminal to have a unique IP address, ensuring a seamless experience when using WiFi and LTE simultaneously. However, both networks can have different delays. In this paper, we investigate the impact of such differences in the delay by means of a real implementation of very tight coupling on an open test bed. We show that aggregation of LTE and WiFi is beneficial only when the delays are similar.

Space-time block codes (STBCs) have been designed and used to achieve the diversity and multiplexing gains in multiple antenna systems. STBCs have been typically designed based on rank and determinant criteria which can provide good performance at high signal-tonoise ratios (SNRs). Later, STBCs are designed based on mutual information to provide good performance at a specific SNR corresponding to the forward error correction (FEC) code rate. However, once the FEC code and STBC are concatenated, to achieve the best performance, STBC should be designed by considering the structure of the FEC code and the corresponding decoder in addition to the code rate. Polar codes are a new class of FEC codes that benefit from a variety of low complexity decoders and simple rate matching. Polar codes can be efficiently designed for a specific channel and STBC. Therefore, by changing the parameters of a specific STBC and optimizing the polar code for each new STBC, the best match between polar codes and STBCs can be found. Throughout this paper, we introduce a simple method for joint optimization of polar codes and STBCs and show that it can substantially improve the performance of the concatenated scheme.

We investigate in this paper the achievable secrecy rate of the multiple-input multiple-output (MIMO) visible light communication (VLC) Gaussian wiretap channel. We consider a system model comprising three nodes: one transmitter (Alice) equipped with multiple fixtures of LEDs, one legitimate receiver (Bob) and one eavesdropper (Eve), each equipped with multiple photo-diodes (PDs). We study at first the problem of optimal signaling scheme that maximizes the achievable secrecy rate of the MIMO VLC wiretap channel. We consider the cases where the location of Eve is known (i.e. perfect channel state information (CSI)) or unknown (i.e. imperfect CSI). Finally, we derive an upper bound on the secrecy capacity that we used to assess the closeness of the achievable secrecy rate to the derived bound.

This paper is directed towards improving both throughput and reliability of 5G wireless Cloud Radio Access Networks (C-RANs) by the synergistic combination of Diversity Coding and Network Coding (DC-NC). In this paper, we directly apply the concept of DC-NC coding to two network scenarios: first, remote radio heads in a CRAN connected to the baseband unit in two hierarchical tiers with optical and wireless fronthaul links, second, most remote radio heads are connected directly to the baseband unit via wireless links. Our results show that the combination of Diversity and Network Coding increases the throughput of fronthaul networks for downlink broadcasting or multicasting applications, while enabling reliable networking with near-instant latency in fault recovery by using forward error control across spatially diverse paths. Moreover, the number of redundant links inherent in Diversity Coding can be decreased using the proposed scheme.

Location fingerprinting is a range-free approach to GPS-free localization. Conventionally, the fingerprint space is defined as a feature vector space where a fingerprint is a vector of location-sensitive measurements associated with a location. However, in practice, it is hard to find a quality feature space that is robust to device heterogeneity and environment and infrastructure dynamics. This paper advocates a fundamentally different model where a fingerprint is defined as a dissimilarity measurement associated with a pair of locations and proposes a localization approach based on geometric embedding.

Free space optical transmission suffers from the line of sight requirement and object induced shadowing. We investigate free-space optical beam steering by means of an optical phased array (OPA) in order to increase signal strength in the desired direction and allow greater mobility. To overcome beam squint and jitter, a novel heterodyne feedback is introduced as a method to stabilize the output beam. This may alleviate the effects of shadowing and enable optical space division multiple access and tracking.

In this paper, we propose a perfectly secure transmission scheme for an asymmetric bidirectional relay channel. The scheme is based on nested lattice coding with keys generated at both legitimate nodes, consisting of unshared random dithers. These keys are indexed by the past secret mutual transmissions and kept secret from other nodes. This model allows legitimate users to transmit safely their secret messages jointly with the artificial noise (dither) without the help of any dedicated internal or external jamming source. Besides, this scheme achieves perfect secrecy at the best known rate for the relay channel in presence of not only an untrusted relay, but also one passive eavesdropper at uplink and one at downlink, even if both eavesdropper channels are noiseless.

In this paper, we study dynamic bandwidth slicing and resource allocation problems to support a mixture of IoT (Internet of Things) and video streaming services. By employing Lyapunov optimization method with time-scale separation approach, we develop algorithms for long time-scale bandwidth slicing, and short time-scale IoT device scheduling, power allocation (for IoT service) and quality decision (for video streaming service). We show through simulations that proposed dynamic bandwidth slicing and resource allocation algorithms outperform the static bandwidth slicing and resource allocation policies in terms of average total cost and average total delay.
