Matlab7官方学习手册，英文版，详细系统了介绍了matlab的基本内容和部分工具箱。(Matlab7 an official study manual, in English, describes in detail the system of the basic content and some matlab toolbox.)

自己的一个实验,验证频率的采样定理.即采样点数要足够大.(own an experiment to test frequency of the sampling theorem. That sampling points should be powerful enough.)

zero crossing rate for detecting zero crossing instants

这是一个完整的OFDM仿真程序，直接运行main_ofdm.m文件就可以打开(This is a complete OFDM simulation program, run directly main_ofdm.m file can be opened)

This letter presents a novel algorithm to compute the instantaneous frequency (IF) of a multicomponent nonstationary signal using a combination of fractional spectrograms (FS). A high resolution time frequency distribution (TFD) is defined by com-bining FS computed using windows of varying lengths and chirp rates. The IF of individual signal components is then computed by applying a peak detection and component extraction procedure

元胞自动机源程序代码，用来模拟组织相变以及动态再结晶过程(Cellular automata source code, to solve organizational phase transition and the dynamic recrystallization)

说明：  作为雷达信号处理系统的一部分，主要利用快速傅里叶变换（FFT）算法完成雷达回波中各距离单元内运动目标的积累检测，另外还包括恒虚警处理然后提出自适应门限杂波图恒虚警处理器及相干杂波图恒虚警处理器。(As a part of radar signal process system, utilizes FFT to achieve radar reflect wave range unit moving target accumulate detect, in addition including CFAR processThen the adaptive threshold clutter map CFAR processor and coherent clutter map CFAR processor are suggested)

使用MATLAB对通信中的一种调制技术QPSK进行编程实现，分析其误码率(The use of MATLAB for communication in a QPSK modulation technique to program implementation, analysis of its error rate)

说明：  完成QPSK的调制和解调 并通过瑞利信道分析误比特性能(QPSK modulation and demodulation completed by analysis of BER performance in Rayleigh Channel)

两阶段DEA模型的matlab程序源码，可以用来计算效率，完全傻瓜式操作。(Two-stage DEA model matlab program source code, can be used to calculate the efficiency, completely fool-type operation.)
