In this contribution the transmission of M-PSK and M-QAM modulated orthogonal frequency division multiplexed (OFDM) signals over an additive white Gaussian noise (AWGN) channel is considered. The degradation of the bit error rate (BER), caused by the presence of carrier frequency offset and carrier phase noise is analytically evaluated. It is shown that for a given BER degradation, the values of the frequency offset and the linewidth of the carrier generator that are allowed for OFDM are orders of magnitude smaller than for single carrier systems carrying the same bit rate. >read more

TL;DR: Results show that the Franks pulse exhibits the best performance among the Nyquist pulses considered in most cases, and the dependence of the BER on the roll-off factor of the pulse employed for a specific system in the presence of frequency offset is investigated.
