分组陪集码的误码特性分析

Error Performance Analysis of Block coset Codes

本文讨论了分组陪集码在最大似然译码与最近陪集译码下的误码特性,这一分析是分别在归一化重量分布和真实距离下做出的,并对其差异进行了比较。本文同时讨论了采用最小距离和最小距离系数进行误码率估计的方法,并指出这些参数可由子码的相应汉明参数得到。

In this paper,the error performance of block coset codes for ML decoding(MLD)and closet coset decoding(CCD)is studied based on both of normalized and real weight. The difference introduced by the two weights is discussed as well. The error performance estimated by the minimal weight and its coefficient is also studied in the paper. Those two parameters can be easily derived from the Hamming weight distribution of the construction codes of a block coset code.
