In this paper we 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. Our numerical results show that
depending on the number of channel taps, the BER performance may degrade with increasing values of Nakagami–m
fading parameters. Phase noise causes significant degradiation of performance of the system. The effects of the pahse
noise on the performancr of the OFDM sysytems have been analytically evaluated. In this project the BER and MSE
performance of the OFDM system over multipath fadding channel was analysed.
