In this letter, we address the problem of broadcasting to receivers with different bandwidths using pulse-position modulation (PPM). A new multiresolution PPM scheme is developed for such a scenario. We show how to construct the scheme for various settings and analyse its performance in the solar-blind region of the ultraviolet (UV) spectrum, where photon counting is attractive. Our key result is that the proposed scheme can increase information rate compared to time-sharing (TS) by superimposing information. |

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. |
