Finite-Blocklength Per-User Error Bounds and Matched-Poisson Decoding for Unsourced Optical Access
Unsourced random access (URA) lets many users share one codebook, with the receiver returning an unordered message list under a per-user probability of error (PUPE) criterion. It has been developed primarily for Gaussian and fading channels. This letter formulates URA for the photon-limited optical regime: a Poisson in...
