Performance Evaluation of Downlink OFDMA Systems
Choi Seung-Kuk · The Journal of the Korean Institute of Information and Communication Engineering · 2006
I evaluate the BER performance of downlink 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.
