Time-dispersive channels can cause intersymbol interference (ISI), a form of distortion that causes symbols to overlap and become indistinguishable by the receiver. For example, in a multipath scattering environment, the receiver sees delayed versions of a symbol transmission, which can interfere with other symbol transmissions. An equalizer attempts to mitigate ISI and improve receiver performance. Communications System Toolbox provides equalization capabilities using one or more Simulink blocks, System objects, or MATLAB functions.

Performance analysis of channel estimation and adaptive equalization in slow fading channelPresented By:
Zhifeng Chen, Electrical and Computer Engineering, University of Florida
ABSTRACT
In our project, we first build up a wireless communication simulator including Gray coding, modulation, different channel models (AWGN, flat fading and frequency selective fading channels), channel estimation, adaptive equalization, and demodulation. Next, we test the effec ....etc

Channel equalization


Introduction
In a communication system, the information is transmitted over a RF channel

The RF channel distorts the transmitted signal
Amplitude, frequency, phase are changed

A receiver should compensate the distortions to recover the transmitted signal
Channel equalization is the compensation process of the distortions in a RF transmission
In order to counter intersymbol interference effect, the observed signal is passed through equalizer whose c ....etc

Abstract

This paper investigates the Wiener and least mean square (LMS) algorithms in the design of traversal tap delay line filters for the purpose of compensating the effect of the communication channel. The designed equalizers remove the distortion caused by the channel from the transmitted signal without requiring any specific model or state-space information. The first approach is based on the a recursive Wiener filtering procedure and is designed using the WienerHopf equation. On the other hand, the second approach uses the LMS algorithm ....etc
