Optimum multi-user detection with point-process observations
Abstract
The derivation and analysis of optimum demodulations for optical digital communication systems is addressed where several users modulate coherent light of the same frequency. The information transfer is represented by a discrete-input multiple-access channel which outputs a scalar conditionally Poisson point-process modeling an ideal photodetector counting process. The rate of the counting process put out by the photodetector is a function of the instantaneous incident power of the sum of the electric fields modulated by several active users. The uncoded minimum error probability achievable with additive light and additive rate Poisson multiple access channels is analyzed in detail.
