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

On the Impact of Carrier Frequency Offsets in OFDM/SDMA Systems
TL;DR: The impact of CFO on the performance of an uplink OFDM/SDMA system is analyzed and different from the existing analysis, it is jointly considered the impact ofCFO on channel estimation and multi-user signal detection.

Maximal power path detection for OFDM timing-advanced synchronization schemes
TL;DR: A method of detecting the estimated starting time index of path with maximal power in channel impulse response is proposed based on conventional preamble with repetitive structure and the scheme makes use of the time diversity provided by time-varying paths and has good error performance.

Analysis of phase noise effects on time-direction differential OFDM receivers
TL;DR: It is shown that Wiener phase noise affects TD differential receivers more than CPEC receivers and FD differential receivers and is compared to that for coherent receivers, common phase error correction (CPEC) receivers, and frequency-direction (FD) differential receivers.

A DFT-based ICI self-cancellation scheme for OFDM systems
TL;DR: A new scheme to reduce the frequency-offset sensitivity of orthogonal frequency division multiplexing (OFDM) systems is proposed, without any redundant modulation, and thus no loss of bandwidth efficiency induced.

Adaptive EKF Based Estimation Method for Phase Noise in CO-OFDM/OQAM System
TL;DR: A new adaptive extended Kalman filter (AEKF) blind scheme to meet the demand of flexibility in dynamic networks is proposed and numerical results show that AEKF can adjust the implementation complexity of PNE according to the varying laser linewidth.
