kalman 的算法的MATLAB 的程序以及仿真(kalman algorithm of the MATLAB program and simulation)

对WCDMA PCCPCH信道信号进行解码，输入是IQ空口信号，本程序会完成信号的解码直至CRC校验(Decode WCDMA PCCPCH channel. The input signal is air interface signal, the program will run until the CRC)

改进boll谱减法，语音增强效果有提高。与MMSE算法不相上下(Improved the boll spectral subtraction speech enhancement effect has been improved. Comparable with the MMSE algorithm)

MATLAB7.x数字信号处理，基本的数字信号处理的程序都在这里了(nearly all the DPS program)

说明：  基于matlab软件的粒子群优化工具箱：psotb-beta-0.3(Matlab software based on particle swarm optimization toolbox: psotb-beta-0.3)

说明：  关于两个目标函数的，利用matlab遗传算法工具箱的优化程序。(The two objective function, using genetic algorithm matlab optimization toolbox procedures.)

matlab 自适应有限元方法，主要为二维椭圆型方程(Adaptive finite element method for two-dimensional elliptic equations)

有约束最优化问题：利用matlab中已有的函数。举了一个利用里面函数求最小值的例子。这是最优化与运筹学中会经常遇到的问题(Constrained optimization problem: using the matlab existing function. For a use inside function minimise example. This was the optimized and operations research will often encounter problems )

一本非常有价值的MAtlab编程参考书，值得一看。(A very valuable reference book MAtlab programming, worth a visit.)

In computer science and information theory, data compression, source coding,[1] or bit-rate reduction involves encoding information using fewer bits than the original representation. Compression can be either be lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy. No information is lost in lossless compression. Lossy compression reduces bits by identifying marginally important information and removing it. The process of reducing the size of a data file is popularly referred to as data compression, although its formal name is source coding (coding done at the source of the data, before it is stored or transmitted).
