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: It is shown that the bit-error rate for an uncoded OFDM system with quadrature amplitude modulation (QAM) can be expressed by the sum of a few integrals, whose number depends on the constellation size.

Channel-independent synchronization of orthogonal frequency division multiple access systems
TL;DR: This work develops synchronization algorithms for both the downlink and the uplink of quasi-synchronous and asynchronous orthogonal frequency division multiple access systems and derives a closed-form variance expression for the carrier-offset estimator at high signal-to-noise ratio (SNR).

TL;DR: The results show that by using the self ICI cancellation scheme proposed, the ICI can be reduced significantly and this OFDM system suffers much less from performance degradation caused by frequency errors than the normal OFDM systems.
