Abstract :
In this paper, we derive exact closed form bit error rate (BER) or symbol error rate (SER) expressions for OFDM systems with carrier frequency offset (CFO). We consider the performance of an OFDM system subject to CFO error in frequency flat Rayleigh fading channel with BPSK and QPSK modulation schemes. Our results can easily be reduced to the respective analytical error rate expressions for the OFDM systems without CFO error. Furthermore, the simulation results are provided to verify the accuracy of the new error rate expressions
