Design and analysis of polar coded cooperation with incremental redundancy for IoT in fading channels

Abstract

In this study, a coded cooperation scheme using polar codes is explored for high‐reliability and low‐user complexity applications such as Internet of Things. Firstly, the cooperation way among the users is carefully designed based on systematic polar codes and cooperative decoding, without decode‐and‐forward protocol at the cooperative user. Meanwhile repetition aided code construction and decoding algorithm of polar code is proposed for the non‐cooperative case in terms of imperfect inter‐user channel. Performance analysis and numerical simulation demonstrate the bit‐error‐rate advantages of proposed polar coded cooperation in fading channels, compared to the no‐cooperation case and normal coded cooperation schemes. Furthermore, overall rate of proposed polar‐coded cooperation is considered to optimize adaptively to increase throughput efficiency.

Polar coded cooperative with Plotkin construction and quasi‐uniform puncturing based on MIMO antennas in half duplex wireless relay network

“…Recently, some cooperative communication based on polar code schemes [19,20] have been proposed. This letter focuses on the Plotkin construction method adopted in literature [13], which has a poor performance in slow fading channel.…”
