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.File | Size | Format | |
