QPSK的系统仿真 simulink 的M文件 讲解了许多关于QPSK 仿真的内容 让大家可以更深一步了解matlab这款软件(QPSK system simulation covering m-file which impart something about Qpsk simulation and let us know about matlab more deep)

This it the code to describe rayleigh distribution

用于体域网体表到体表CM3（场景S4与S5）传输的信道模型，900MHz频段(This model is meant for body to body surface CM3 (Scenario S4 & S5) for 900 MHz)

用著名的Gram-Charlier级数展开画变量的概率密度曲线或累积分布曲线。在程序中可选。需要用到6阶半不变量。(Use the famous painting Gram-Charlier series expansion to plot the probability density curve or cumulative distribution curve. Need to use 6-order half-invariant.)

说明：  实现协作频谱感知，采用压缩感知方法，并对不同虚警率下的正确判决概率进行对比仿真。(To achieve cooperative spectrum sensing, compressed sensing method is adopted, and the correct decision probability under different false alarm rates is compared and simulated.)

说明：  matlab中一些重要的课件和资料，比较有用啊！(matlab courseware and some important information, more useful ah!)

在matlab环境下使用模糊PID和常规数字PID控制buck电路效果对比(Environment in matlab fuzzy PID and conventional digital PID control circuit buck contrast effect)
