Abstract

The capacity of the discrete-time channel affected by both additive Gaussian\nnoise and Wiener phase noise is studied. Novel inner and outer bounds are\npresented, which differ of at most 6.65 bits per channel use for all channel\nparameters. The capacity of this model can be subdivided in three regimes: (i)\nfor large values of the frequency noise variance, the channel behaves similarly\nto a channel with circularly uniform iid phase noise; (ii) when the frequency\nnoise variance is small, the effects of the additive noise dominate over those\nof the phase noise, while (iii) for intermediate values of the frequency noise\nvariance, the transmission rate over the phase modulation channel has to be\nreduced due to the presence of phase noise.\n
