MATLAB中文论坛MATLAB 信号处理与通信板块发表的帖子：瑞利衰落信道mqam误码率仿真曲线和理论值不符。有没有好人帮忙看下哪里不对红色部分是主要代码，不知道需不需要多次生成瑞利信道再来求平均的误码率，图中结果是只调用了一次 rayleighchan 的结果，误码率和理论值差别. OSTBCEncoder — Ortogonal Space-Time Block Codes Encoder; comm. Now that Mathematica 9 has been released, I thought I'd work through the exercise again. A channel object is a type of MATLAB variable that contains information about the channel, such as the maximum Doppler shift.
