On the capacity of the block-memoryless phase-noise channel

Journal article, 2012

Bounds are presented on the capacity of the block-memoryless phase-noise channel. The bounds capture the first two terms in the asymptotic expansion of capacity for SNR going to infinity and turn out to be tight for a large range of SNR values of practical interest. Through these bounds, the capacity dependency on the coherence time of the phase-noise process is determined.
