matlab 模式识别工具包 希望能对你们有用(pattern recognition matlab toolkit hope to be useful to you)

实现不同噪声情况下qpsk的调制，并得出了星座图。(Implement different noise situation of QPSK modulation and the constellation diagram is obtained. )

scalogram.m Function to calculate the phase and amplitude scalograms of a 1D signal. The analysis is done using quadrature pairs of log Gabor wavelets.

对小波信号处理采用新的方法，三种预值法和杨氏估计的方法等。(Wavelet signal processing on a new method, three kinds of prediction value and the method of young s estimate, etc. )

some notes abou svd in matlab functions

costas环的simulink实现，可以直接在matlab上运行实现通信系统中的载波同步，对于学习或设计通信系统有很大帮助(simulink realization of costas loop that can run directly on the matlab implementation of carrier synchronization in communications systems, communications systems for the study or design of great help)

基于matlab的电能质量检测仿真，其中包含小波变换，S变换，FFT，dq变换，直接打开Mypower就可运行，没有界面。(Matlab-based simulation of power quality detection, which contains the wavelet transform, S transform, FFT, dq transformation directly open Mypower can run, there is no interface.)

μ律PCM编码，小信号放大，大信号缩小，非均匀量化实现的一种方式，实用。(μ-law PCM coding, small signal amplification, large signal narrow, one way to achieve a non-uniform quantization, and practical.)
