Performance Analysis of Polar Coded IHDAF Relaying for Next Generation Cellular Networks

Cooperative relay networks play a vital role in improving the coverage and capacity of cellular networks. In order to achieve high reliability, relaying should be used with channel codes. In this paper, the hybrid relaying protocol based on the incremental procedure is proposed through polar codes. It provides 40% gain when the threshold signal-to-noise ratio between source and relay equals 5 and threshold signal-to-noise ratio between source and destination is optimal. Simulation result illustrates that incremental HDAF using polar codes outperform in Alamouti scheme compared to single-input-single-output systems.
