PERFORMANCE ANALYSIS OF PREAMBLE DETECTION IN WIMAX 802.16E SYSTEM USING FADING CHANNEL WITH OFDM

Abstract

Objective of thesis is to study about the WiMAX model, OFDM and detect preamble. Preamble detection can be done by many methods such as correlation so compare the methods and find which one is better for preamble detection techniques. In correlation methods varying the value of correlation lag and find out what is the effect on detection technique. In this preamble detection method (SC, ML, MMSE and MNC-GM) we used communication channel Rayleigh fading also used modulation techniques QAM. The performance has been concluded based Sample versus Detection value and output through MATLAB-R2013a Simulation.
