one of the best ways to have a blind channel estimation is using a precoding after before IDFT operation in OFDM systems,this simulation shows the precoding infulence on the system.

用matlab实现双极性归零码的仿真，波形及其功率谱，可以选择占空比(Achieved with the bipolar zero code matlab simulation, waveform and its power spectrum, you can select the duty cycle)

说明：  IIR低通滤波器，matlab与verilog程序完全对应(iir low pass filter matlab result fully match the verilog output.)

说明：  对卡尔曼滤波器的测试等，请观看。谢谢了，谢谢。(Testing on the Kalman filter, please watch. Thank you, thank you.)

用于人脸识别的PCAKNN算法，算法可成功运行。(a useful program, )

三层平板介质光波导计算，该平板波导主要由3层均匀介质构成，中间的芯层折射率为n1，厚度为d，芯区生长在折射率为n2的衬底上，芯区上面的覆盖层折射率为n3。这里考虑的是n1大于n2大于n3。(Three-layer flat-plate dielectric waveguide, the flat waveguide is composed of three uniform media, the refractive index of the middle layer is n1, the thickness is d, the core area is grown on the substrate with refractive index n2, The refractive index of the layer is n3. It is considered here that n1 is greater than n2 and greater than n3.)
