FIR 底通和带通滤波器和IIR 底通和带通滤波器，对信号进行频谱分析及滤波，pwm整流器的建模仿真，粒子图像分割及匹配均为自行编制的子例程，单径或多径瑞利衰落信道仿真，真的是一个好程序，解耦，恢复原信号，基于互功率谱的时延估计。- Bottom-pass and band-pass FIR and IIR filter bottom pass and band-pass filter, The signal spectral analysis and filtering, Modeling and simulation pwm rectifier Particle image segmentation and matching subroutines themselves are prepared, Single path or multipath Rayleigh fading channel simulation, Really is a good program, Decoupling, restore the original signal, Based on the time delay estimation of power spectrum.
