在源信号和传输信道未知情况下，只利用接收天线的观测数据抽取源信号，称为盲信号分离.盲信号分离不仅是信号处理界、而且也是神经网络界的研究热点课题，在无线数据通信、雷达、图像、语音、医学以及地震信号处理等领域都具有广阔的应用前景.采用自然梯度法和分阶段学习法。(The source signal and transmission channel is unknown circumstances, using only observational data extraction receiving antenna source signal, known as blind signal separation. Blind signal separation is not only the signal processing community, but also a neural network hot topic in research circles, in the wireless data communications , radar images, audio, medical and seismic signal processing and other fields have broad application prospects. and the phases using the natural gradient learning method.)

一些滤波器设计方法的演示程序，包括窗函数法等，程序之中会有注释，主要是用来学习数字信号处理(Some filter design methods demonstration program, including the window function method, etc., will be among the program notes, is primarily used for learning digital signal processing)

解决中立性微分方程的Matlab程序. 中立性微分方程即微分带时延的。(Matlab program to solve the differential equations of neutral. Use matlab to simulate.)

国外计算机经典教材，MATLAB有限元分析与应用。该书为中译本，详尽介绍了有限元分析的各种方法。(MATLAB guide to finite elements.)

SAR雷达系统完整信号产生、压缩、识别过程，最齐全雷达系统matlab仿真程序，代码段详细注释文字说明，适合论文仿真参考(SAR radar system signal, compression, complete identification process, the most complete radar system matlab simulation program, code detailed annotation text, suitable for paper simulation reference)

基于AIC,BIC准则的变量选择方法的matlab程序实现代码(Based on AIC, BIC criteria for variable selection methods matlab program implementation code)

说明：  多尺度特征熵，用于机械振动信号特征提取和故障诊断等方面(Multi-scale feature entropy for mechanical vibration signal feature extraction and fault diagnosis)

基于JPcap的ip数据包的分析，详细讲解了完成数据捕获分析的过程，其中包含了JPcap基本类的使用 (Based on the analysis JPcap ip packet detail on the completion of the analysis of the data capture process, which includes the use of the basic classes JPcap Analysis of IP data packet based on JPcap, explain in detail the process of data capture and analysis, including the use of JPcap basic class)

此程序经本人调试,完全能实现编码的仿真功能,而且在程序中有必要的说明,增加了程序的可读性.(this procedure by my tests, is fully capable of achieving functional simulation codes, but the procedure is necessary to note, increase the readability of programs.)

it is example 3 of caputer 4 from widrow book.it is so good for learning many things about adaptive filters
