In this work it is introduced a scheme to reduce the effects of a differential GPS signal when acting as interference in narrowband powerline communications systems. The novelty is the use of specific cyclostationary characteristics of the interfering signal for its cancellation. A robust detection method (the forward consecutive mean excision algorithm) is used to define if the interfering signal...
We derive three novel data-aided CFO estimators based on a new autocorrelation function which is defined using cyclostationary properties of the repetitive preamble. The first estimator is a generalization of a classic estimator, and the other two take advantage of the structure of the new autocorrelation function to improve the estimation for low CFO. In addition, the performance of the proposed...
The increasing data rates in wireless mobile systems involve transmitting in wideband channels giving rise to multi-path propagation. The classical way to attenuate intersymbol interference due to multipath channels is to use time domain equalizers, which are complex if the channel has many taps. OFDM signals allow an easy equalization of multipath channels, although the resulting high peak to average...
