FFT

It is Radar System design and signal prcessing code based on standard algorithm .this is vey important for biggener those who are working on Radar signal processing area.This code contain various chapter. this is basically chapter No4

说明：  很多matlab程序，很适合初学者进行学习哦！！(many matlab programs，you can study，if you ware newone！)

matlab code for Firefly Algorithm

这是基于matlab的关于Mel频率倒谱系数（MelFrequencyCepstrumCoefficient，MFCC）的代码，对大家理解有一定帮助。(This is based on the matlab Mel Frequency Cepstral Coefficients (MelFrequencyCepstrumCoefficient, MFCC) code for us to understand some help.)

Matlab code with GUI for decoding ASCII characters into readable text

matlab写的图像Zigzag置乱的函数，特别适用于初学者学习(matlab write Zigzag calculation function, especially for beginners to learn)

说明：  刀刃法测mtf，希望对你有所帮助，一个朋友给的，我不太会调试(MTF measurement by blade method)

说明：  瑞利衰落信道中空时编码仿真程序： 1.2根发射天线、1根接收天线2.最高信噪比为12dB，即仿真范围为0dB到12dB3.在每个信噪比条件下,误符号数超过20即停止该信噪比条件下的仿真4.每一帧数据为24个QPSK符号(Rayleigh Fading Channels Space-Time Coding Simulation Program: 1.2 transmission antennas, a receiving antenna 2. The highest SNR 12dB, that is, simulation range of 0dB to 12dB3. In each signal to noise ratio conditions, the number of symbol error over 20 that is, to stop the signal to noise ratio under the conditions of simulation 4. each frame 24 QPSK data symbols)

对正交编码（Hadamard）+BPSK调制进行分析而用matlab进行仿真。(Hadamard code is a kind of error correcting code. )

该程序是基于虚拟力的无线传感器网络优化，算法收敛速度快，且能达到比较满意的性能。(The program is based on the virtual force wireless sensor network optimization, the algorithm convergence speed, and can achieve satisfactory performance. )
