In digital communication channel coding plays a very vital role in reliable communication. In communication systems error detection and correction also plays a very important role. In this paper, a joint combination of Reed Solomon (RS) channel coding and polar code is proposed.RS codes belong to linear codes and perform error correction and channel coding. The RS encoding is performed prior to polar encoding followed by polar decoding which includes cyclic redundancy check (CRC) based successive cancellation of list (SCL) and stack. This successive cancellation-based decoding depends on log likelihood ratio (LLR). The relay is decoded with RS decoder and it provides higher performance than the existing techniques. The symbol error probability is analysed with various K/N values and various modulation schemes like BPSK, QPSK and QAM. The proposed technique outperforms with the existing techniques. The proposed technique outperforms with the existing techniques.
