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 way among users carefully designed based on systematic cooperative decoding, without decode-and-forward protocol at user. Meanwhile repetition aided code construction decoding algorithm proposed non-cooperative case in terms imperfect inter-user channel. Performance analysis numerical simulation demonstrate bit-error-rate advantages fading channels, compared to no-cooperation normal schemes. Furthermore, overall rate polar-coded considered optimize adaptively increase throughput efficiency.
