这是基于MATLAB中的stateflow的一个简单的单水箱状态机(Single Water Tank State Machine)

滤波器设计是信号处理的核心问题之一,Matlab软件在多个研究领域都有着广泛的应用。 本文介绍了基于Matlab环境下,用窗函数设计法实现FIR数字滤波器的设计,并阐述了与以前人 们常用的设计方法的区别,给出了设计实例。仿真结果表明,设计结果的各项性能指标均达到指定 要求,且设计过程简便易行。 (The design of filters is a core problem in signal processing. MATLAB software iswidely used inmany research fields. This article introduces themethod ofusingwindow function to design FIR digital filters based onMATLAB and its differences from the tradi- tional designmethods. And itgives a design example. The simulation shows that the design results canmeet the requirements verywell and the design procedure is very simple and practica.l )

Adaptive Filter. This script shows the BER performance of several types of equalizers in a static channel with a null in the passband. The script constructs and implements a linear equalizer object and a decision feedback equalizer (DFE) object. It also initializes and invokes a maximum likelihood sequence estimation (MLSE) equalizer. The MLSE equalizer is first invoked with perfect channel knowledge, then with a straightforward but imperfect channel estimation technique. (Adaptive Filter.
