对OFDM系统的仿真分析，对于初接触通信系统的朋友，会有所帮助，进一步了解ofdm。(OFDM system simulation and analysis，for who early contact with communication systems will help to better understand the ofdm。)

Matlab Simulink simulation of a single phase cyclo converter.

空间信号的波达方向（Direction of Arrival，简称DOA）估计作为阵列信号处理研究的一个主要课题，在近些年来越来越得到大量的关注和研究。它可实现对空间中信源信号的准确的角度估计，实现信源方位等参数的具体精确检测，并且还具有很高的分辨力。这些特性使得DOA估计在声呐、通信及雷达等多种领域具有广阔的应用和发展前景。此程序为面阵中二维角度估计算法程序。(direction of arrival,usually called DOA,has been an important subject recently.This program contains unitary esprit)

LLE算法用Matlab实现，完全能达到LLE算法的要求。(LLE algorithm using Matlab, fully able to meet the requirements of the LLE algorithm.)

说明：  使用交叉熵算法，对组合优化问题，逐步逼近最优解完成寻优(Using cross entropy method to optimize the problem)

说明：  适用于电力系统仿真曲线的振荡频率分析的PRONY 分析程序(Prony analysis program for oscillation frequency analysis of power system simulation curve)

佛洛伊德方法用二值模型来形成多灰度图像的真实效果，希望分享(Digital halftoning is the process of converting a continuous-tone images into strictly black and white images such that, when viewed by the human visual system, the pattern creates an illusion of being a continuous shade of gray. )

CDMA中传统多用户检测和MMSE多用户检测比较（前向和反向链路）(CDMA traditional MMSE multi-user detection and multi-user detection comparison (forward and reverse link))

说明：  实现ASK调制的详细过程，对学习很有帮助(ASK modulation to achieve the detailed process of learning is helpful)
