In this paper, the authors present an efficient technique for the BER of OFDM system over Nakagami - m fading channels, using well known characteristics function based analysis approach. The average BER expressed in terms of the higher transcendental function such as the confluent hyper geometric functions. Their numerical results show that depending on the number of channel taps, the BER performance may degrade with increasing values of Nakagami - m fading parameters. Orthogonal frequency division multiplexing is being used more and more in telecommunication, wired and wireless. DVB and DAB already use this modulation technique and ADSL is based on it.
