Performance analysis of digital pulse interval modulation for underwater optical communication link in anisotropy oceanic turbulence

Abstract

The performance analysis of underwater optical wireless communication (UOWC) with digital pulse interval modulation in anisotropy oceanic turbulence environment is investigated. We aim at the packet error rate (PER) of UOWC system using Gaussian-Schell model beam and avalanche photodiode receiver. Based on the generalized Huygens-Fresnel principle, the received light intensity is derived. The effects of PER variations with anisotropy factor, modulation order of DPIM, coherent parameters of the GSM and the ratio of temperature to salinity contributions to the refractive index spectrum are investigated.
