协作通信系统中的LDPC码性能分析研究
Performance analysis of LDPC codes in cooperative communication system
摘要
Abstract
Cooperative communication is an important scheme to meet the increasing requirement of capacity of communication system. Performance degradation due to the error propagation on the relay node can be improved effectively by using LDPC codes in the cooperative communication system. The fundamental theory of encoding and decoding of LDPC codes are given firstly. Then the analysis model of cooperative communication system based on LDPC codes is described. The simulation results and analysis are presented. Simulation results show that the performance of cooperative communication system based on(3,6) regular LDPC codes is much better than that of single link transmission.关键词
