通过M atlab 模拟了随机产生的一定概率分布的信号序列, 叠加高斯噪声后利用最大后验概率(MAP)检 测到的误码率, 做出BER~ SNR曲线, 并与理论计算得到的曲线进行比较, 两者吻合.(M atlab simulated by a certain probability distribution of random signal sequence, use of superposition of Gaussian noise is the maximum a posteriori (MAP) detection to the error rate, making BER ~ SNR curves obtained with the theoretical curve of the combined fit.)

敝人最近整理的关于MatLab中的遗传算法工具箱Gads的资料，不敢独享，希望能起到一定的帮助作用(myself recently finishing on the MatLab genetic algorithm toolbox Gads information, not exclusive, hope to play a helpful role)

自己编写的一段matlab程序，主要是用于EMD信号消噪(a sention of programme above signal denoising using EMD method,which is used for learning the method in "noise filtering using empirical mode decomposition")
