Abstract :
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´.
