Performance Evaluation of Uplink OFDMA Systems  

Choi, Seung-Kuk (인천대학교 정보통신공학과)
Abstract
I evaluate the BER performance of uplink OFDMA systems in time variant Rayleigh Doppler fading channel, considering the carrier frequency offset and the nonlinear high power amplifier. I obtain the required output back-off of the nonlinear amplifier and value of frequency offset for good BER performance. And I also analyze the BER degradation upon Doppler fading channel.
Keywords
