The bit error rate expression of the binary phase‐shift keying modulation scheme has been derived in a frequency selective fading channel for the fractional Fourier transform (FRFT) based orthogonal frequency‐division multiplexing (OFDM) system in the presence of carrier frequency offset (CFO). The performance of the FRFT based OFDM system has been found to be better than FFT‐based OFDM at different values of FRFT angle parameter ‘α’.
