Abstract
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. >

Estimation of Phase Noise in Oscillators with Colored Noise Sources

TL;DR: In this article, a soft-input maximum a posteriori PN estimator and a modified soft input extended Kalman smoother are proposed, and compared with those studied in the literature in terms of mean square error of PN estimation, and symbol error rate of the considered communication system.

Swift Jamming Attack on Frequency Offset Estimation: The Achilles’ Heel of OFDM Systems

TL;DR: This paper demonstrates how an adversary can exploit the known preamble structure of OFDM-based wireless systems, particularly IEEE802.11a/g/n/ac, to launch a very stealth (low energy/duty cycle) reactive jamming attack against the FO estimation mechanism.

The effect of interpolation on the BER performance of narrowband BPSK and (O)QPSK on Rician-fading channels

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.

Digital HDTV broadcasting over the CATV distribution system

TL;DR: This contribution deals with the digital broadcasting of HDTV channels over the cable television (CATV) distribution system, using either single-carrier QAM or an orthogonal frequency division multiplex of many QAM carriers to represent an HDTV channel.
