说明：  加性高斯白噪声下，FQPSK调制的常规OQPSK检测(awgn channel, convention OQPSK demodulationfor FQPSK modulationfor)

被控对象为G(S)=400/（s*s+500s）,首先运行模糊控制器程序chap4_2.m,并将模糊推理系统保存在a2中，然后运行模糊控制SIMULIK程序。位置指令为0.5sin（10t）,simulink见chap4_3(Controlled object is G (S) = 400/(s* s+500s), first run the fuzzy controller program chap4_2.m, and stored in a2 fuzzy inference system, and then run the fuzzy control SIMULIK program. Position command is 0.5sin (10t), simulink see chap4_3)

matlab中对图形轮廓的特征提取代码，程序实现，(matlab in the graphic outline feature extraction code, program implementation,)

数字图像处理中的小波去噪代码！ 希望对大家有用 matlab(Digital image processing in the wavelet de-noising code! Want to be useful to everyone matlab)

说明：  对一幅图像的进行小波包分解，然后提取每一层的系数(image of a pair of wavelet packet decomposition, and then extract the coefficient of each layer)

This programs are very useful for time prediction.

arious linear time-invariant electromagnetic systems are most conveniently analyzed in the frequency domain because there exist mature computational techniques (e.g., [1]) and related software (e.g., [2, 3]). Most measurements of antennas and microwave systems are also performed in the frequency domain (using vector network analyzers), yielding a discrete set of frequency-domain data. In order to obtain the time-domain response of such systems

因而本文基于MATLAB 针对Nakagami 衰落信道仿真了它的统计 特性,包括接收信号的复包络模拟和在具有最大比合并分集下的电平通过率及平均衰落持续时间的性能分析。重点在于理解和建立采用 MATLAB 进行信道信真的方法及对Nakagami 衰落信道本身统计特性的理解。(Based on MATLAB which Nakagami fading channel simulation for its statistical properties, including the received signal complex envelope simulation and has the maximum ratio combining diversity under the level crossing rate and average fade duration of the performance analysis. Emphasis is on understanding and the establishment of the channel using MATLAB and the letter is really way Nakagami fading channel statistical characteristics of their own understanding.)

说明：   matlab灰色预测的通用算法程序，很好的套用模版(universal algorithm for Matlab gray prediction procedure, apply the template)

频率调制和解调 频率调制是将消息信号的积分作为相位，也就是用消息信号去调制频率 ( Of the frequency modulation and demodulation frequency modulation is the integral of a signal of the message as the phase, that is, with the message signal to the modulation frequency)
