摘要 提出了采用码率兼容LDPC码为纠错码时IR_HARQ方式下的LDPC新译码方法,该方法利用前次译码后的信息作为重传后再次译码的初始输入信息,有效地利用了上次译码的成果。对该新译码方法进行了仿真评价,仿真表明新方法在系统吞吐量和迭代次数方面都能提供更好的性能。 This paper proposes a new decoding method based on IR_HARQ scheme that uses code-compatible LDPC codes as the FEC codes. It can use the former decoding result, which can improve the performance of decoding scheme. This paper also evaluates the new decoding method by simulation. The results show that better performance both on system throughput and iterative times can be obtained.
