Inspection of Error Performance and Interference Avoidance Technique for Cooperative Relay in Underlay D2D Networks

Abstract

5G wireless standard has significant participation for Device to Device (D2D) communication system, channel state estimation and cooperative relay techniques. This paper investigates the great role of the cohabitation of these technologies by proposing the electronic relay. This relay is a collection of collaborative techniques. The selection between them is accomplished automatically after inspecting the channel state information (CSI). In addition, interference avoidance techniques with the electronic relay are proposed to reduce the interference. A deeper construe of these techniques is illustrated. Also, the term of outage probability of both communication links is demonstrated. MATLAB simulator is used. The outage performance of proposed techniques is compared with the corresponding previous techniques. As illustrated in the simulation results. The SNR gain increases by 2.9 dB due to utilizing the interference avoidance. Moreover, the effect of increasing the D2D numbers on the system outage probability is introduced.
