Construction and Optimization for Adaptive Polar Coded Cooperation

In this letter, an adaptive polar coded cooperation (APCC) is explored in the fading channels. In terms of the imperfect inter-user channels, the cooperation way of APCC is carefully designed based on the multi-level structure of polar codes. Meanwhile code construction with dynamic-optimized information sets ensures the coding gains at the receivers. Moreover, the adaptive code rates of two cooperative users are optimized by maximizing the throughput efficiency. Simulation results demonstrate the bit error rate and throughput advantages of APCC over the existing coded cooperation schemes.
