Abstract
The variation in the channel impulse response during one OFDM symbol, which occurs in fast fading channel environments, destroys the orthogonality between the subcarriers. As a result, a complicated multiple distortion and an extra additive distortion component are introduced. A theoretical derivation of the BER formula is presented, which involves a proposed method for calculating the probability density function (PDF) of the sum of N (N⩾3) correlated Rayleigh random variables (RVs). The results obtained using the derived BER formula agree well with the simulation results
