摘要 由于LDPC码的优良性能,因此在信息可靠传输中有良好的应用前景。本文提出了一种将BP算法和基于列表的SIHO(软输入硬输出)算法相结合的译码算法,通过与BP、MLD算法的误码率性能和译码复杂度比较,本算法复杂度比MLD有明显降低,而在性能上优于BP算法并接近MLD译码算法。 Low-density parity-check code (LDPC) with good application foreground has excellent performance. A news LDPC decoding algorithm, which combined SIHO ( soft-input hard-output ) list-based decoding with belief propagation (BP) decoding is presented. Comparing with BP and MLD algorithm in performance and complexity, the complexity of the proposed decoding is reduced apparently and the performance approaches to MLD decoding.
