In this paper, we consider communications impaired by phase noise and we propose an iterative multi-sample receiver, where the received signal is sampled with more than one sample per symbol interval.

Our simulation results show an improved performance with respect to a 'classical' receiver, where phase synchronization relies on one sample per symbol interval only, for high phase noise scenarios.

Abstract

In this paper, we consider communications impaired by phase noise and we propose an iterative multi-sample receiver, where the received signal is sampled with more than one sample per symbol interval. The approach is pragmatic in the sense that demodulation/decoding is performed separately from synchronization and relies on 'off-the-shelf' subblocks. In particular, we extend a recently proposed Maximum A-posteriori Probability (MAP)-based algorithm for phase synchronization by exploiting oversampling at the receiver. Our simulation results show an improved performance with respect to a 'classical' receiver, where phase synchronization relies on one sample per symbol interval only, for high phase noise scenarios.
