用小波进行图像处理，以及一个QPSK调制程序，还有用MATLAB实现二维小波分解与重构程序，请大家指正-wavelet image processing, and a QPSK modulation procedure, there are two-dimensional MATLAB wavelet decomposition and reconstruction process, please correct

Produce lfm,tfm,sfm,pfm,bpsk,qpsk cw ledai signal .Use short-time Fourier transform arrive at the instantaneous frequency.-Produce lfm, tfm, sfm, pfm, bpsk, qpsk cw ledai signal. Use short-time Fourier transform arrive at the instantaneous frequency.

数字通信系统仿真，基于MATLAB软件的QPSK仿真源程序代码。-Digital communication system simulation, simulation based on MATLAB software source code for QPSK.

matlab仿真代码源文件，空时编码采用G4，QPSK星座映射-matlab G4space time block coding

matlab下各种调制方式的实现，实现了BPSK，QPSK，8PSK和16QAM，可以根据数据的不同改写数据实现调用-Realization matlab various modulation methods, to achieve the BPSK, QPSK, 8PSK and 16QAM, can call depending on the rewriting of the data
