中文说明：重复累积（RA）码是一种新型的纠错码，不仅具有与Turbo码、LDPC码相同的优越性能，而且其编译码算法与码长呈线性关系。本书主要介绍了RA码的编译码原理及其在通信系统中的应用，共分9章，主要包括RA码的研究背景及国内外发展现状、RA编译码原理、RA码的简化译码算法、RA码的优化设计方法、RA码在高斯/删除混合信道上的性能分析及优化设计、RA码在比特交织编码调制系统中的应用、RA码在远程光纤通信系统及混合ARQ技术中的应用等方面的内容。
English Description：
Repeat Accumulate (RA) code is a new error correcting code, not only has the Turbo code, an LDPC code can be the same advantages, and its encoding and decoding algorithms and the code length is linear. This book introduces the principle of RA codec codes and its application in the communication system, is divided into nine chapters, including background and current situation of domestic and foreign research and development of RA codes, RA Decoding Principles, RA simplified code decoding algorithm , RA code optimization method, RA code Gauss / delete channel mixing performance analysis and optimization design, RA code in bit interleaved coded modulation system application, RA codes in the remote optical fiber communication systems and hybrid ARQ techniques content and other aspects.
