this paper, we present an efficient technique for the SER of OFDM system over Rayleigh fading channels, using well known characteristics function (CHF) based analysis approach. The exact probability density function of a sum of Rayleigh random vectors are used to derive the expression for the error rates of OFDM system. The average SER expressed in terms of the exponential and Bessel functions. Further to improve the system performance error-rate analysis is extended to a system using multichannel reception with maximal ratio combining.
