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

Byungju Lim,Young-Chai Ko +1 more
TL;DR: This paper provides the analysis of signal-to-interference ratio (SIR) for each of the cases when phase noise and synchronization errors of the desired user occur in frequency selective channel and proposes the receiver filter for GFDM systems that is optimized to maximize SIR with CFO in additive white Gaussian noise channel.

Sensitivity of multi-user filter-bank multicarrier systems to synchronization errors
T. Fusco,A. Petrella,Mario Tanda +2 more
TL;DR: It is shown that, as all multicarrier systems, FBMC systems are very sensitive to synchronization errors, since timing errors and carrier frequency offsets produce intercarrier interference and interference between successive symbols, however, in an asynchronous multi-user scenario FB MC systems are more robust than OFDM systems to time and frequency misalignments among the users.
