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

Analysis of OFDM in the presence of frequency offset and a method to reduce performance degradation
TL;DR: The main idea is to map each data symbol a/sub k/ which is to be transmitted onto a pair of non-adjacent subcarriers k and (N-1-k), with weightings +1 and -1, other than to a single subcarrier.

TL;DR: It is shown that with an effective SNR estimation, quantified measurement can be achieved in a short simulation time for such distortions as caused by non-ideal channel estimation, signal clipping, carrier frequency offset, and many other sources in the system.

TL;DR: This work proposes a new class of SF codes called ICI self-cancellation SF (ISC-SF) codes to combat ICI effectively even with high FO, and demonstrates that ISC-SF codes can also mitigate the ICI caused by phase noise and time varying channels.

TL;DR: By using the phase noise correlation function, a new phase noise mitigation scheme is proposed for the general M/sub T//spl times/M/sub R/ MIMO WLANs system with channel estimation errors, which achieves significant performance gain with high spectral efficiency, requiring few pilots, and is robust to spatial correlation and channel estimation Errors.
