Design And Implementation Of Mobile Wimax Baseband Transceiver For Different Channel Estimation Algorithms

Abstract

This paper refers to channel estimation based on time-domain channel statistics. Using a general model for International Telecommunication Union (ITU) channel model, the aim of the paper is to find out the most suitable channel estimation algorithms for the existing Mobile WiMAX and modified the bit error rate for this system. Starting with the analysis of channel estimation algorithms, we present the Minimum Mean Square Error) MMSE ( and Least Square) LS( estimators and compromising between performances under different channel scenarios. The bit error rate for a 16-QAM system is presented by methods of matlab simulation results.
