说明：  归零编码，适用于FMT（滤波多音调治）技术(RZ code applicable to FMT (multi-tone filter rule) technology)

这是一个实现拉格朗日插值的数学程序，也很经典。(This is a mathematical realization of Lagrange interpolation process is also very classic.)

Investigation of the relation between amount of VoIP speech data and performance in speaker identification task over VoIP Networks

这个是我编的改进了的语音处理里面的普减法，效果及其显著，可以直接编译运行(This is my series of improved voice processing inside Pu subtraction, and its significant effect, you can direct the compiler to run)

说明：  001小波变换及其MATLAB工具的应用(001 DWT and MATLAB application tools)

Implements Frequency Shift Keyed (FSK) receiver at Bell 202 standard

Linear dynamical system. This set of functions performs inference and learning of a linear Kalman filter model. Inference is carried out via forward-backward smoothing, and learning is accomplished via the expectation maximization algorithm.

说明：  在matlab下实现无线环境多径信道仿真，并给出相应的频谱。(Simulate the multipath channel in the wireless environment , and give the corresponding spectrum.)
