Abstract :
In this paper, performance of OFDM digital communication systems have been analyzed over correlated Nakagami-m fading channel using maximal ratio combining (MRC) diversity at the receiver. We have studied statistical characteristics of inter-carrier-interference over correlated Nakagami-m fading channel and also presented signal to interference noise ratio (SINR) over correlated Nakagami-m fading channels. We also derived a novel mathematical expression of bit error rate (BER) for QPSK/QFSK OFDM systems.
