Discrete Signaling for Non-Coherent, Single-Antenna, Rayleigh Block-Fading Channels

摘要

Discrete signaling schemes are proposed for non-coherent, single-antenna, Rayleigh block-fading channels (RBFCs). The schemes are inspired by the capacity-achieving distribution. A nested Monte-Carlo method is developed to compute the mutual information across the RBFC. Mutual information curves are presented and compared with other signaling schemes proposed in the literature.
