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

A new carrier frequency loop for OFDM systems
TL;DR: A decision-directed carrier frequency estimator for OFDM systems is derived that has a closed loop structure and is based on maximum likelihood inspired methods and a simplified version of the loop is developed that can be implemented with relatively low complexity and acceptable degradations.

TL;DR: The simulation results show that the proposed algorithm gives a more accurate estimation of symbol timing and sampling frequency offset and provides a wider acquisition range for carrier frequency offset, compared with Park's algorithm.
Chirp-based multicarrier modulation
TL;DR: In this article, the authors demonstrate that in doubly-dispersive environments, a multicarrier system based on a fractional Fourier transform (FrFT) can achieve a better concentration of power near the main diagonal of the equivalent channel matrix compared to standard orthogonal frequency division multiplexing (OFDM).
