Shorten LDPC Codes with Better Performance
Hui Ya Li, Jian Ying Shi, Jin Xi Men · Applied Mechanics and Materials · 2014
In this paper, the bipartite graphical structure of LDPC codes is studied, some methodology for designing shorten LDPC Codes are presented. The performance evaluation of shorten LDPC codes presented provides easy and effective strategy in selecting appropriate shorten scheme, avoiding the complex encoding and iterative decoding steps. The shorten LDPC codes whose minimum code weight greater and length 4-cycle free have better performance.
