A simple upper bound on the information rate (IR) of digital communications over phase noise‐impaired channels is proposed. In particular, the transmission of linearly modulated signals, such as QAM, at high‐signal‐to‐noise ratio is considered, thus extending previous literature results for phase modulated signals, e.g. PSK. A simulation‐based lower bound on the IR shows that the proposed bound is tight for small‐medium size constellations and large phase noise.
