介绍了GMSK的背景，基本原理，调制解调方式等内容（英文）(GMSK introduces the background, basic principles, modulation and demodulation, etc. (English))

说明：  通过matlab五电平调制，实现更优选择的切换(Through five level modulation, better switching can be achieved)

说明：  基于正态分布的最小错误率Bayes分类器(Minimum error rate Bayes classifier based on normal distribution)

matlab实例编程一百个源程序，内有运行后界面图像＆源代码(100 source files, after running within the interface images & source code)

使用SGP模型进行轨道计算的matlab源码 使用两行星历TLE(Simplified perturbations models are a set of five mathematical models (SGP, SGP4, SDP4, SGP8 and SDP8) used to calculate orbital state vectors of satellites and space debris relative to the Earth-centered inertial coordinate system. This set of models is often referred to collectively as SGP4 due to the frequency of use of that model particularly with two-line element sets produced by NORAD and NASA.)

子波分析是一种日益获得广泛应用的信号处理新技 术, 具有良好的时-频局部化特性, 尤其适用于时变及非平 稳信号。本文简述了子波函数与子波展开的基本概念, 利用 展缩子波和调和子波将信号及信号均方值进行时-频两维 分布。最后采用了三种子波分析方法对轴承故障进行诊断, 即使对现有各种方法尚难以诊断的滚动体故障, 也能获得 满意的结果, 说明子波分析的确为机械故障诊断提供了强 有力的分析手段。(Wavelet a nalysis, as a new technique of signal processing , possesses ex cellent characteristic of time-frequency localization and is suitable for analyzing the time-var ying or transient signals. In this paper , the basic concepts of wavelet function and wavelet expansion are briefly introduced. The time frequency distribution of signal and its energy are obtained by decomposition via dilating wavelet and harmanic wavelet. )

LU－Zerlegung und Vektorisierung(LU-Zerlegung und Vektorisierung)

说明：  这是一个关于基本的最小二乘的程序，只用Matlab语言编写的。(This is a basic program about least squares, written in Matlab language.)
