摘要: 用多维并行联接及扩展技术设计出一种新型的近仙农理论极限的码:并行联接扩展汉明码.编码器由多个扩展汉明码的并行联接组成.译码器是基于文中给出的篱笆图技术,用最大后验概率的迭代译码方法得到的.

关键词: 并行联接扩展汉明码, 译码, 编码

Abstract: This paper designs a new class of codes:parallel concatenated extended Hammin codes using a combination of multi-dimensional parallel concatenation and extension techniques. The encoder is built using a parallel concatenation of multiple extended Hamming codes. The decoder uses the iterative decoding of the maximum a posterior algorithm based on the trellis technique, discussed in the paper.

Key words: coding, parallel concatenated extended Hammin codes, decoding
