摘要
Abstract
The error performance of Additive White Gaussian Noise(AWGN) channel and Rayleigh fading channel is analyzed. Then the relation between diversity gain and communicating reliability over Rayleigh fading channel is studied. A formula of code error probability upper bound is derived for wireless communication system in which linear block code is applied. It shows the relation between diversity gain of linear block code through Rayleigh channel and its minimum hamming distance. Based on Monte Carlo method, the simulation is carried on this problem. A comparative analysis is made on the experimental and theoretical result, and results show that the diversity gain of linear block code under relay fading channel is equivalent to its minimum hamming distance.关键词
