DEAR SIR/MAM,
I m a b.tech 4th year student. i hv seminar in near days. i got the topic adaptive channel equalization but not getting enough info on this topic and nt getting any idea to prepare the seminar report. plz help.. by posting a seminar report on the above mentioned topic.

Channel Estimation & Equalization for WiMAX

Introduction

The Altera channel estimation and equalization modules for mobile
worldwide interoperability for microwave access (WiMAX) can be used
to accelerate the development of mobile broadband wireless basestations
based on the IEE 802.16e-2005 standard .
f For more information on IEE 802.16e-2005, refer to the IEE Standard for
Local and Metropolitan Area Networks Part 16: Air Interface for Fixed and
Mobile Broadband Wireless Access Systems, Dece ....etc

In order to implement the adaptive equalizer, we need to generate a reference signal for the adaptive
algorithm. For the initial adaptation of the filter coefficients we need at the receiver to be able to
generate a replica of the transmitted data sequence. This known sequence is referred to as the
training sequence.
How can I do this? ....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

lms algorithm adaptive beamforming matlab code

Abstract

Array processing involves manipulation of signals induced on various antenna elements. Its capabilities of steering nulls to reduce co channel interferences and pointing independent beams toward various mobiles, as well as its ability to provide estimates of directions of radiating sources, make it attractive to a mobile communications system designer. This paper presents 8-elements array with inter-element spacing /2 an optimum value to avoid grating lobes. An Adaptive beamforming is a ....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

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.
