| Abstract: | In this paper,we investigate the bit error rate(BER) performance of constant envelope orthogonal frequency-division multiple(CE-OFDM) system with maximum ratio combining diversity reception in Nakagami-fading channels with arbitrary fading index.Using the moment generating function-based analysis approach,we obtain the lower bound expression of average BER for CE-OFDM systems with rectangular M-ary quadrature amplitude modulation.Simulation results show that the lower bound matchs the average BER for CE-OFD... |
