Coded-Cooperation based Multi-Relay Algorithm for Device-to-Device Communication in 5G Cellular Networks

In this paper, the authors have considered a coded cooperative based multi-relay Device to Device (D2D) system for underlay 5G cognitive radio networks. The Coded cooperation, a cooperative relaying technique is an attractive choice for bandwidth efficiency and better connectivity. The Outage Probability expression is derived for the proposed system considering the interference limit between the secondary D2D user system and the primary user system over the Nakagami-m fading channel. The effect of the channel parameter and number of relays (M) on the outage performance is also studied.
