一种线性分组码的查表译码法及其应用

针对纠正两个随机错误的线性分组码,采用重复查表译码法,通过多次查询含一个错误的伴随式与错误图样的译码表,实现了一种占有很少存储空间的查表译码算法。该算法在码长较短时译码的计算量较少,可适用于利用单片机等低运算能力情况下的通信应用中。文中对纠正2个错误的（26,16）缩短循环码的译码进行了实现,验证了算法的可行性。

Research on Look-up Table Decoding of Linear Block Codes

This paper presents a memory saved algorithm of linear block code decoders by using look-up tables.This algorithm can correct 2 random errors by iterative checking the same syndrome of the error pattern table.When the code words contain short length vectors,this look-up table decoding only need few calculations which can be applied to the low-calculation-ability communication systems(e.g.,SCM).In addition,this paper realizes feasibility analysis through correcting 2 random errors based on(26,16) shorten cyc...
