Decode and Forward Mode (DF) is one of the best cooperation techniques used for half duplex relay channels. In this article, we propose a scheme DF low complexity based on polar codes, using a special technique: a decoder by the successive cancellation list (SCL) assisted by a cyclic redundancy check (CRC). With this proposal, the decoder at the relay node is designed to reduce decoding errors by exploiting the CRC detection technique and the probability of metric of L candidate decoding paths. Simulation results show that our scheme outperforms in terms of bit error rate some previous work, especially when the source-relay channel is a high SNR region.
