Abstract :
A precise method for calculating the bit error probability (BEP) of an iterative equalization-based oversampled OFDM system on fading channels in the presence of spectral nulls is derived. Several signaling formats, such as binary phase-shift keying, quaternary phase-shift keying, and M-ary quadrature amplitude modulation are considered.
