Abstract

Theoretical analysis of multiresolution pulse-position modulation (M/N-PPM) predicts its ability to improve information rate; so far, however, its performance in practice is unknown. In this letter, we report results of a proof-of-concept experiment, in which an M/N-PPM scheme is used for broadcasting over photon-counting channels. We show that M/N-PPM has a potential to improve information rate by demonstrating its ability to superimpose information. We provide results of data rates, bit-error rates (BERs), and discuss some channel impairments that affect link performance.
