Abstract

The fast changing frequency nonselective Ricean fading channel introduces a complicated multiple distortion and an extra additive noise component foran OFDM system. The multiple distortion is the average of the sum of N(N greater than or equal to 3) correlated Ricean random variables. In this Letter, we propose an approximate technique for calculating the probability density function (PDF) of the multiple distortion under the assumption that the channel response changes in a linear fashion during one OFDM symbol. As aresult, the bit error rate (BER) formula of a BPSK: modulated OFDM system is derived. The results obtained using the derived formula describe well the OFDM performance under the time variant channel and match very well with the simulation results.
