Abstract
In this paper, we analyze the information rate of a phase-noise discrete-time channel obtained by sampling the continuous-time channel. In particular, we assume that more than one sample per data symbol may be available at the receiver, so that this channel is referred to as "oversampled." This work extends previous literature work by taking into account the presence of a bandlimited shaping pulse at the transmitter with time support not limited to the symbol period, possibly causing inter-symbol interference. Our results show that for sufficiently large signal-to-noise ratio (SNR) it is possible to recover the performance degradation caused by phase noise, also for quite large values of the phase noise intensity.File | Size | Format | |
