说明：  matlab下数字信号处理实现例程，包括FFT进行信号频谱分析，窗函数法设计FIR滤波器，IIR滤波器的实现等(matlab under the realization of digital signal processing routines, including the FFT signal spectral analysis, the window function design FIR filters, IIR filters to achieve such)

kalman filter This script implements the linear filter and shows its performance On a second order under-damped LTI systems In the first part, a noisy model with two state variables is simulated and in the second part, kalman filtering is applied to estimate the real observations

matlab实现基本的通信仿真技术bpsk(To achieve basic communications simulation technology bpsk using matlab)

This code permit to simulate the sound received on microphones given their positions, the positions of the sound source(s), the frequency sampling of acquisition and the speed of sound. Assuming anechoical conditions.

行程编码的matlab实现。编码后的图像存储在变量E中,该变量是一个三纬树组,前两纬表示起始像素的横、纵坐标，第三纬表示该行程的颜色值。(Matlab coding realize itinerary. Encoded image is stored in the variable E, the variable is a three-wai Tree Group, the former two-wai express start pixel horizontal, vertical coordinates, the third weft express the color values of the trip.)
