为了提高TA8435H的最大工作电流极限，今天对控制板的驱动芯片散热系统作了改进(TA8435H)

自己编写的polar码 编译码算法程序 matlab 可用(polarcode matlab)

通过AR模型模拟得到风荷载，其模拟是有davenport风速谱得到的(Wind load is obtained by AR model simulation, which is based on Davenport wind speed spectrum.)

说明：  产生电压扰动数据，PSCAD仿真，可作为各类信号处理仿真的数据源(Creates a voltage disturbance data, PSCAD simulation, can be used as various types of signal processing simulation data source)

瑞利衰落信道（Rayleigh fading channel）是一种无线电信号传播环境的统计模型。这种模型假设信号通过无线信道之后，其信号幅度是随机的，即“衰落”，并且其包络服从瑞利分布。(Rayleigh fading channel, Rayleigh fading channel) is a statistical model of radio signal propagation environment. This model assumes that the signal through a wireless channel, its signal amplitude is random, or "decline", and its envelope obey Rayleigh distribution. )

Matlab通信仿真及应用源码，很详尽，也可以作为matlab通信初学者运用(Matlab of Communication Simulation and application source code, very detailed matlab communication beginners to use, but also can be used as)

直接序列扩频通信系统仿真程序 生成的信息码的波形图 扩频码如图 PSK调制后的波形 解调后的波形 解扩并滤波后的波形 (The waveform in Figure PSK modulated waveforms direct sequence spread spectrum communication system simulation code information generated spreading code waveforms despreading and after filtering the demodulated)
