采用频域FFT变换实现对雷达回波信号的MTI处理，有效的提高信噪比，本程序是对这一过程的验证。(Using frequency domain FFT transform of radar echo signal processing on the MTI, effectively improve the SNR, the procedures for the process validation.)

给定时间序列信号，计算Hjorth参数的mobility和complexity.(computes the Hjorth parameters mobility and complexity.)

MATLAB和maple语言均未直接提供求解fourier级数的系数的直接函数，自己动手丰衣足食，下面提供了一个代码，大家可以参照下 (MATLAB language, and maple were not directly solve the fourier series coefficients of the direct function, it-yourself ample food and clothing, the following provides a code, we can refer to the next)

利用M函数仿真扩频通信系统。6个用户的CDMA的同步通信系统，每个用户利用L＝31的Gold码，进行扩频，信道为AWGN信道，接收端利用匹配滤波器进行检测。绘出当N＝10000个发射比特下，SNR＝0：15（dB）时的误码率曲线。 (M function simulation using Spread Spectrum Communication System. 6 simultaneous users of CDMA communication system, each user of the L = 31 the use of Gold codes for spread spectrum, channel for the AWGN channel, the receiving end to detect the use of matched filter. Drawn when N = 10000 bits of transmission, SNR = 0:15 (dB) when the bit error rate curve.)

说明：  电子科技大学的一篇关于多传感器融合的好文章,请站长审阅(University of Electronic Science and Technology of multi-sensor fusion on a good article, please review head)

说明：  三相整流和单项逆变，该模型能够完成三相交流对单相交流的转换(3 AC-DC-1 AC)

实现短时傅里叶变换，真的挺好用的，大家可以十四看看呀(TFRSTFT this is a program ,you can try it in you computer)

说明：  用遗传算法进行多元函数的优化，是测试函数与数据集的基本方法(Using genetic algorithm to optimize multivariate function is the basic method of testing function and data set)
