Paper Abstract

Optical wireless communication performance through multi-scattering channels has been researched widely in recent years due to the increasing interest in laser satellite-ground links and urban optical wireless communication. The predominant sources of performance degradation have been identified as the spatial, angular and temporal spread of the propagating beam in the presence of a multi-scattering medium, which cause reduced power reception and inter-signal-interference (ISI), and noise due to background illumination and to receiver circuitry. In consequence, the signal-to-noise ratio (SNR) and the bit-error-rate (BER) are degraded. However, coherence effects due to multipath interference caused by a scattering propagation channel do not appear to have been treated in detail in the scientific literature. In this paper we attempt a theoretical analysis of coherence interference in optical wireless communication through scattering channels, and try to quantify the resultant performance degradation.
