clustering using kmeans. Good for HMM

this file implement the conversion from decimal format to binary 2 bit format. can be used for communications simulations. implemented as a matlab function file. very easy to use

基于多尺度的小波边缘检测的matlab的代码，含有去噪算法(Edge detection based on wavelet multiscale matlab code, containing de-noising algorithm)

利用MATLAB实现了跳频信号的调制和解调，给出了频谱图。(The use of MATLAB implementation of the frequency hopping signal modulation and demodulation, give the frequency spectrum.)

均匀量化和非均匀量化在性能上存在着显著的差异，这种差异可以用信号通过量化器后的量躁比来反映出来。本程序用曲线表示了理论和实际两个方面下两种量化的量躁比。从而可观察他们的性能上的差别。(There are significant differences with the function between Uniform quantization and non-uniform quantization ,which can be quantified by SNR from the quantizer.This program use the curves to denote the SNR of theory and practical signal.Then we can observe the performance of the differences.)

VPI与matlab联合仿真，自定义信号产生程序(matlab and VPI)

Atmel抯 AVR controller offers an Analog to Digital Converter with 10-bit resolution. In most cases 10-bit resolution is sufficient, but in some cases higher accuracy is desired. Special signal processing techniques can be used to improve the resolution of the measurement. By using a method called 慜versampling and Decimation?higher resolution might be achieved, without using an external ADC. This Application Note explains the method, and which conditions need to be fulfilled to make this method work properly
