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

Abstract

Recently, polar code has attracted the attention of many scholars and has been developed as a code technology in coded-cooperative communication. We pro-pose a polar code scheme based on Plotkin structure and quasi-uniform punching (PC-QUP). Then we apply the PC-QUP to coded-cooperative sce-nario and built to a new coded-cooperative scheme, which is called PCC-QUP scheme. The coded-cooperative scheme based on polar code is studied on the aspects of codeword construction and performance optimization. Further, we apply the proposed schemes to space-time block coding (STBC) to explore the performance of the scheme. Monte Carlo simulation results show that the pro-posed cooperative PCC-QUP-STBC scheme can obtain a lower bit error ratio (BER) than its corresponding noncooperative scheme.
