Fast Walsh-Hadamard Transform

可以在图上拖动的均衡器,但没有播放功能.可以自行添加。(a equalizer controlable by dragging on the map, without play function)

利用小波变换对处理地震资料的matlab代码，可以对井资料和地震资料处理，适合勘探地震的初学者和信号分析的初学者(Seismic data processing matlab code, can be well data and seismic data processing, seismic exploration for beginners, is based on the original 2.1 adds new code)

Nonsubsampled contourlet transform

this file describes and run the HALFTONING of a picture.

说明：  这是一个基本的CDMA系统的调制与解调系统。包括随机信号的产生，调制还有相应的解调。(This is a basic CDMA coding and decoding system, it includes random signal generator and coding and decoding modules )

Comparison of performance for 2-PPM and 2-PAM under two pulse shapes, Gaussian Pulse and Hermit Pulse with Three scenarios are considered (5, 20, and50 users).

说明：  stft(含:短时傅立叶变换 Gabor变换等)(stft (containing: STFT Gabor transform, etc.))

该程序模拟仿真16QAM传输系统，有助于理解调制过程。(Simulation program to realize 16QAM transmission system)
