LDPC码在均衡技术中的应用

LDPC Decoding Appliment in Combined Equalization Techniques

LDPC码的BP译码算法是一种迭代算法,译码复杂度低,可实行完全的并行操作.介绍BP译码算法,以及LDPC码与均衡技术结合的基本原理,并提出了一种基于MMSE均衡技术的线性LDPC均衡算法.

The stand belief propagation（BP） algorithm of LDPC codes is an iterative algorithm. The complexity of BP algorithm is low. We briefly introduce the decoding using so - called BP algorithm together with the practical steps achieving this goal, and the rationale of combined equalization and LDPC codes. Finally, we bring forward an algorithm of combined MMSE equalization and LDPC codes.
