在这一章中,低密度奇偶校验(LDPC)码,一类强大的迭代译码纠错码,介绍。本章首先回顾了信息论中的一些基本概念和结果,如香农信道容量和信道编码定理。然后概述了闪存通道模型。最后,它解决LDPC码描述其结构和有效的实现,以及它们的解码算法。仿真结果也提供。
In this chapter, low-density parity-check (LDPC) codes, a class of powerful iteratively decodable error correcting codes, are introduced. The chapter first reviews some basic concepts and results in information theory such as Shannon’s channel capacity and channel coding theorem. It then overviews the Flash memory channel model. Finally, it addresses LDPC codes describing both their structure and efficient implementation, and their decoding algorithms. Simulation results are also provided.
