WiMAX Performance Analysis under the Effect of Doppler's Shift

Navgeet Singh | Dr. Amita Soni

Abstract: In this paper; an effort has been made to illustrate the performance of WiMAX communication system under the effect of Dopplers Shift for the Multipath fading channel using MATLAB Simulink. An end-to-end baseband model of the physical layer of a Wireless Metropolitan Area Network (WMAN) over the Multipath Rician Fading environment has been used. Doppler Shift is one of the salient factors considered while designing a mobile wireless communication system for prescribing the different standards of the communication system like data rates according to the speeds of the mobile user. By analyzing the scatter plots of received signal prior to demodulation; a frequency range has been found within which the fading effects on the received signal can be overcome for proper signal recovery.
