摘      要：Low-density parity-check(LDPC)codes are widely used due to their significant errorcorrection capability and linear decoding ***,it is not sufficient for LDPC codes to satisfy the ultra low bit error rate(BER)requirement of next-generation ultra-high-speed communications due to the error floor *** to the residual error characteristics of LDPC codes,we consider using the high rate Reed-Solomon(RS)codes as the outer codes to construct LDPC-RS product codes to eliminate the error floor and propose the hybrid error-erasure-correction decoding algorithm for the outer code to exploit erasure-correction capability ***,the overall performance of product codes is improved using iteration between outer and inner *** results validate that BER of the product code with the proposed hybrid algorithm is lower than that of the product code with no erasure *** with other product codes using LDPC codes,the proposed LDPC-RS product code with the same code rate has much better performance and smaller rate loss attributed to the maximum distance separable(MDS)property and significant erasure-correction capability of RS codes.
