DTMF

mu-law quantizer for Matlab

路径损耗和阴影衰落的建模。分析不同用户在基站区域内接收信号的功率(Path loss and shadow fading modeling)

Ucsd编写的matlab的GARCH模型分析与预测。包括两个安装包和安装说明（各种matlab版本都有），很详细。主要是好多网上其他无法运行，这个步骤我刚刚试试过，可以运行，(UCSD matlab prepared the GARCH model analysis and forecast. Includes two installation package and installation instructions (there are a variety of matlab version), in great detail. Is mainly a lot of other can not run the Internet, the steps I have just had a try, you can run,)

说明：  声波方程正演模拟小模型波场绘制。只有一层，震源在中间。C程序，Matlab绘图。(Acoustic wave equation forward modeling small-scale model wave field rendering. Only one layer, source in the middle. C program, Matlab graphics.)

生成m序列，并验证游程特性。 (generate m sequence，and verify run length characteristic ！)

基于牛顿法，现采用编程来计算最优解，matlab程序和简要说明文档。(newton method for optimization)

包含了m序列 gold序列 kasami序列和ovsf码的所有伪码产生器(Contains a sequence of m sequences gold Kasami sequences and OVSF code of all pseudo-code generator)

receiver for vblast

matlab仿真，主要基于通信建模仿真等，本程序免费，欢迎下载，免费共享。(matlab simulation, simulation modeling is mainly based communications, this program free, welcome to download, free to share.)

说明：  仿真声呐的相移波束形成，内部包含详细的程序注解，供新手进行学习(The phase-shifting beamforming of the simulated sonar contains detailed program annotation for novice learning)
