摘要
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.
Signal series in a certain probability distribution added by Gauss noise is detected by MAP ( Maximum A posterior Probability),the bit error ratio (BER) is simulated with Matlab; the curve of BER - SNR is plotted, it consists with the curve plotted through theoretical calculation.
