Performance analysis is carried out for an optical wireless link considering coherence interference through multiscattering channels using OOK and M-ary PPM modulations. It can conclude that higher order PPM offers better performance than OOK in the presence of multiscattering.
Optical wireless communication--in space and in both outdoor and indoor terrestrial applications is rapidly becoming a major feature of modern life and so it has been the subject of much research in recent years. The major sources of performance degradation have been identified as the spatial, angular, and temporal spread of the propagating beam when the propagation channel is multiscattering, resulting...
