自适应均衡系统在simulink中的仿真研究

Simulation of Adaptive Equilibrium System in Simulink

数据在无线通信过程中,会因为传输过程中存在的多径效应造成码间干扰,干扰随时间变化着,对数据的接收造成很大困难。自适应均衡就是用于解决码间干扰的一种技术。自适应均衡器是自适应滤波器的一种典型应用。本文对自适应均衡算法(LMS算法)所在的数字通信系统用matlab中simulink环境进行了建模仿真,构建的通信系统很好地反映了自适应均衡器模块(LMS算法)在克服多径效应方面起到了关键作用。

In the process of wireless communication, effect in the transmission process, and the interference inter-symbol interference is caused , China） by the muhipath changes with time, which makes it difficult to receive the data. Adaptive equalization is a technique used to solve inter-symbol interference. Adaptive equalizer is a typical application of adaptive filter. In this paper, the digital communication system of adaptive equalization algorithm （LMS algorithm） is modeling simulated in the simulink environment of Matlap. The constructed communication system is a good reflection of the adaptive equalizer module （ LMS algorithm） and has played a key role.
