Network polar coded cooperation with joint SC decoding

A network polar coded-cooperative (NPCC) scheme with joint successive cancellation (SC) decoding at the destination is proposed. Plotkin´s construction is employed to build polar codes; however, the proposed construction is opposite to the conventional method where two short codes jointly construct a longer length code. In the proposed construction the two short codes (subcodes) are derived from the longer length code. The proposed construction is then employed to achieve coded cooperation between two users, and also offers a network coding, which not only improves the data rate of the coded cooperative system but also improves the overall bit error rate performance which is shown with the help of numerical simulations.
