说明：  个人写的一些matlab神经网络的函数和算法，希望大家喜欢(Some people write matlab neural network functions and algorithms, hope you like)

一个IEEE802.11b的实用例子，供正在学习的朋友参考。(5.5 Mbps CCK Simulation using specs from IEEE 802.11b, No guarantees and warantees!)

本程序是关于卫星上下变频的简单的实现算法，首先产生双边带调制信号，与收本振混频后，通过低通滤波器完成下变频。再与发本振混频，通过高通滤波器后完成上变频(This program is a simple algorithm on the satellite and down-conversion, the first double-sideband modulation signal generated, after the close of the oscillator mixer, low-pass filter complete the conversion. Again and send the local oscillator mixer, followed by the completion of the high-pass filter frequency)

自适应信号处理，滤波器设计，基于lms最小均方平方算法(Adaptive signal processing, filter design, based lms square LMS algorithm)

求解量子力学的薛定谔方程，说明见readme.ttxt，使用matlab编制。能现运行start.m (Solving the Schrodinger equation of quantum mechanics shows see readme.ttxt, using matlab prepared. Can now run start.m)

针对NL-Mreans算法运算时间较长的问题，提出了优化，大大缩短了时间。(To solve the problem of long operation time of NL-Means algorithm, an optimization method is proposed, which greatly shortens the time.)

This is universal codebook generator with LBG algorithm by myself.

说明：  是有关DSP中著名的契比雪夫的窗函数,还是不错的,欢迎使用(DSP is the famous Lease Chebyshev window function, or good, welcomed the use of)
