对于卫星系统的优化，目前比较前沿的是基于多学科优化(MDO)的方法，文中重点对此方法进行了介绍。(For the satellite system optimization, more cutting edge is based on the current multi-disciplinary optimization (MDO) methods, the paper focus on this method were introduced.)

利用matlab实现的基于离散小波变换的数字水印代码(Matlab realize the use of discrete wavelet transform-based digital watermarking code)

雷达的信号处理 恒虚警检测 MTD 分快慢门限(Radar signal processing MTD CFAR detection threshold of speed)

可以用来计算分歧度，这个分析度是信息论中的一个概念，类似于熵。(we can use it to calculate the klsym divergence)

this code solves schrodiger

分别对线性调频信号、非线性调频信号、连续波信号、频率编码信号和相位编码信号的进行了信噪比特性分析，较为有用的程序，与大家分享(Chirp signal, non-linear FM signal, continuous wave signal frequency coded signal and phase encoded signals were signal-to-noise ratio characteristic analysis, a more useful program, to share with you)

灰色预测是就灰色系统所做的预测。所谓灰色系统是介于白色系统和黑箱系统之间的过渡系统。其具体的含义是:如果某一系统的全部信息已知为白色系统，全部信息未知为黑箱系统，部分信息已知，部分信息未知，那么这一系统就是灰色系统。(Grey prediction is the prediction of grey system. The so-called grey system is a transitional system between the white system and the black box system. Its concrete meaning is: if all information of a system is known as a white system, all information is unknown as a black box system, some information is known, and some information is unknown, then this system is a grey system.)

使用频率变换法设计微波三通带带通滤波器。其中Z_P_Triple是实现有低通原型到双通带的变换。建议下载此程序者先下载本人上传的Source-Load-Coupling.rar，因为部分程序在其中(DESIGN OF CROSS-COUPLED TRIPLE-BAND FILTER USING FREQUENCY TRANSFORMATION)

仿真分析了MSK传输的数据，差分后的数据、加权前的I,Q路、加权后的I/Q路及MSK调制后的信号(Simulation analysis of the the MSK data transmission, differential data, weighted before I, Q Road, weighted I/Q Road and MSK modulation signal)

语种识别matlab程序，里面包括gmm，hmm模型的训练和测试，，，，，，(Language recognition matlab program, which includes training and testing gmm, hmm model,,,,,,)
