说明：  认知无线电中基于能量检测的频谱检测方法，matlab实现！(Energy dection,in Cognitive Radio,program by matlab)

Calculates the luminance of a square using Matlab.

本程序是利用真实的外部输入测井数据，在matlab环境下生成井的合成地震记录，并且将地震记录成图显示，最终达到地层标定的目的。(This procedure is the use of real external input log data to generate synthetic seismograms well in matlab environment, and seismic mapping records show, and ultimately the formation calibration purposes.)

本上传资料为simulink学习教程，通过此教程可以了解一些基本操作。(The upload data to simulink tutorials through this tutorial to learn some of the basic operations.)

Image Watermarking using DWT algorithm

课程设计需要运用MATLAB编程实现2ASK,2FSK,2PSK，2DPSK调制解调过程，并且输出其调制后的波形，画出频谱、功率谱密度图，并比较各种调制的误码率情况，讨论其调制效果。(Curriculum design requires the use of MATLAB programming 2ASK 2FSK, 2PSK 2DPSK modulation demodulation process and output modulated waveform, draw the spectrum, power spectrum density map and compare various modulation BER discuss its modulation effect.)

在录制好音源后，通过该程序，可以求解出各自声音信号的基音周期。(Recording audio through the program can solve each pitch period of the voice signal.)
