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 IEEE 802.16e-2005 standard .
f For more information on IEEE 802.16e-2005, refer to the IEEE Standard for
Local and Metropolitan Area Networks Part 16: Air Interface for Fixed and
Mobile Broadband Wireless Access ....etc

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 ef ....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 thr ....etc

it is very useful for any distortion to get it from the original signal to avoid jamming so we use both wiener filter and lms so i need to study both of two cases to see what is new

Channel Estimation for OFDM System with Two Training Symbols Aided and Polynomial Fitting




INTRODUCTION

ORTHOGONAL frequency division multiplexing
(OFDM) is a high spectral efficiency transmission
scheme. It divides a wideband signal into many orthogonal
subcarriers and induces a symbol period that is much
longer than the bit duration. However, a long symbol
period is sensitive to the time-varying channel in wireless
communications. The channel respo ....etc

Dear Sir,
Can you please provide the code for An improved dft based channel estimation algorithm for mimo ofdm systems, as i have the code but the execution results are not related with the abstract results.
thanks in advance. ....etc
