数字调制方式：2ASK，2FSK，2PSK，MSK，QPSK等信号的调制代码（m文件）实现。(Digital modulation techniques：2ASK，2FSK，2PSK，MSK，QPSK)

SCATTERFIELD - Interactive nearfield viewer Syntax: scatterfield Description: SCATTERFIELD plot the fields/currents/charges within the antenna resonator or on its surface at plane wave incidence. SHOULD be executed after EIGENFREQ. Only an incident plane wave is allowed as an excitation. MATLAB Antenna Toolbox Draft 05, Antenna Lab, ECE, WPI, mat05@ece.wpi.edu Authors: S. Kulkarni, A. Marut, S. Makarov

This is a code for periodic impusive noise in ofdm based power line communications. It is implemented in matlab.

dct and idct for image.matlab实现信息序列的嵌入和提取(dct and idct for image.matlab realize embedded information and extract sequence)

这是parzen窗估计的典型例子，大家可以直接学习，是个不可多得的好材料。(This is a typical example of the estimated parzen window, we can learn, is a rare good material.)

该源代码是模式识别课程作业。通过K平均算法实现聚类的目的。效果比较好。另外本人还设计了等高线法，用于聚类，思想较好，效果一般，但是值得参考。(This code is a Pattern Recognition homework. It use Kmeans to clustering, and get a good result. It s good for a reference.)

matlab实现调制解调程序，并适用matlab的绘图功能描述了具体图像实现(matlab achieve modulation and demodulation process and the application of mapping matlab functions described in the specific image to achieve)

在MATLAB环境下，对全数字锁相环的仿真，分析锁相环的性能参数(In the MATLAB environment, to all-digital phase-locked loop simulation, analysis of the performance parameters of phase-locked loop)

只是一个关于短时平均过零率的matlab代码(Just a short-time average zero-crossing rate on the matlab code)
