说明：  matlab中similink入门指南。希望能够大家有些帮助，尤其对于刚刚入门的朋友。(matlab in similink Getting Started Guide. Some hope to be able to help everyone, especially for entry-just friends.)

说明：  Matlab低通，高通，带通滤波器的设计都有，说明很详细，并且带有实例。(Matlab low pass, high pass, band-pass filter design are to illustrate in great detail and with examples.)

Simulation Of Patch Antenna Using MATLAB

关于恒速风电机机组的matlab仿真，可以了解恒速风电机组的相关运行特性(modeling and simulation of Constant Speed Wind Power Unit This simulation gives an example of Modeling and simulation of Constant Speed Wind Power (CSWP) coupled with wind turbine. Latest researches and developments which have been published in imminent journals, you can get it if you are interested in it. Because of the advantages of the CSWP over other generators it is being used for most of the wind applications. Various researches have been done in modelling and simulation field of CSWP coupled with wind turbine. This simulation visualise the researches in the area of study of CSWP, its modelling, simulation and performance analysis of CSWP coupled with wind turbine. )

作为对184号规则的推广，Nagel和Schreckberg在1992年提出了一个模拟车辆交通的元胞自动机模型，即NaSch模型（也有人称它为NaSch模型）。 (Schreckberg was proposed in 1992 by a simulation of vehicle traffic cellular automaton model, namely the NaSch model (also called it NaSch model))

时隙ALOHA协议是对ALOHA协议的简单修改，把传输时间分为一个个时隙，数据包只能在时隙的开始进行并行传输。在当前的时隙中产生的数据包只能在下一个时隙的开始进行并行传输。(Time slot ALOHA protocol is simple modification of ALOHA protocol, the transmission time is divided into a time slot, packets can only be the beginning of time slot for parallel transmission. In the current time slot of packets can only be the beginning of the next time slot for parallel transmission. )

同步技术在接收机中是非常重要的，直接关系到解调的好坏，本程序提供了符号同步的源程序代码(Symbol synchronization )

说明：  对使用matlab编程的基础知识做了详尽的介绍。(Matlab on the use of basic knowledge of programming to do the detail.)

自动控制工具库，包含常用的阶跃响应，冲击响应等，可以利用一个函数实现控制系统的模拟功能(Library automation tools, including common step response, impulse response, etc., can use a function of the control system of analog functions)

Abstract— We propose a simple speech compression algorithm using subband division and ADPCM (Adaptive Differential Pulse Code Modulation) algorithm. Although speech data are stored in a semiconductor memory device, its capacity and the available network capacity are limited. Therefore, it is necessary to compress the data as much as possible. The first is that the reconstructed datum must be understood correctly. Speech signal is compressed with a ratio of 1/4 using the proposed subband division and ADPCM (Adaptive Differential Pulse Code Modulation) algorithm.
