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

Effect of carrier frequency offset on OFDM systems for multipath fading channels
TL;DR: The paper presents an exact analysis of the effect of the carrier frequency offset on orthogonal frequency division multiplexing (OFDM) systems for a general multipath fading channel and determines how small the frequency offset should be in order to maintain the SNR degradation to negligible levels.

TL;DR: The general PRCC scheme not only inherits advantages of the conventional CC scheme, such as backward compatibility with the existing OFDM systems, low receiver complexity, and two-path diversity, but also provides better performance, especially at high frequency offset situations.

Sensitivity of orthogonal frequency-division multiplexed systems to carrier and clock synchronization errors
Heidi Steendam,Marc Moeneclaey +1 more
TL;DR: It is shown that OFDM systems are quite sensitive to carrier frequency offset and clock frequency offset : in the presence of these impairments, the signal-to-noise ratio (SNR) at the input of the decision device is a decreasing function of the number of carriers.

TL;DR: By means of theoretical analysis, it is demonstrated that even simple interpolators, operating at only a few samples per symbol, yield BER degradations that are limited to a small fraction of a dB.
