Abstract
The needs of high speed broadband wireless access at lower cost and easy deployment to meet the modern mobile services leads in the emergence of an another IEEE standard called Worldwide Interoperability for Microwave Access (WiMAX). The limitations of conventional Broadband wireless access have been overcomewith the scalable features of WiMAX. The main purpose of this paper is to evaluate, analyze and compare the performance of a WiMAX under different data rate and coding techniques. For this purpose a simulation model of WiMAX PHY layer transmitter and Receiver has been designed using MATLAB. The model was implemented at the Physical Layer using ConvolutionalEncoding Rate of 3/416-QAM modulations and transmitted with 256 OFDM symbols in both the AWGN and Rayleigh fading channels. In this thesis, the performance analysis is being done by studying the bit loss and Packet losses that occurred during transmission over channel. It is found that the performance of transmitted data not only depends on parameters like Signal to noise ratio (SNR) and Signal power but also on the effect of transmission channel.
