Abstract
Rich atmospheric scattering in the ultraviolet (UV) enables non-line-of sight (NLOS) communications, opening a new optical paradigm. In this paper, we incorporate an experimentally validated NLOS channel path loss model and quantitatively predict the performance of a combination of modulation and coding techniques. Our study includes OOK, PPM, MPPM, repetition coding and trellis coding. We consider both Poisson and Gaussian noise assumptions, appropriate for different operating regimes, with a focus on achievable range as a critical parameter in NLOS operation.
