Lower bit-error-rate polar-LDPC concatenated coding for wireless communication systems

This paper reports low bit-error-rate (BER) polar codes concatenated low density parity check (LDPC) codes for wireless communication systems. The LDPC code has been validated on the error correction capable to approaching the theoretical value. However, the BER performance of this code is still limited because of the effect of the error floor. Therefore, a concatenated coding scheme based on polar and LDPC codes has been proposed to further reduce the BER. Compared to Reed-Solomon codes concatenated with LDPC codes, this polar-LDPC concatenated coding has better BER performance.
