Investigation of the Scattering Noise in Underwater Optical Wireless Communications

In underwater optical wireless communications (UOWC), scattering of the propagating light beam results in both intensity and phase variations, which limit transmission link range channel bandwidth, respectively. Scattering photons while through is a random process, channel-dependent noise. this work, we introduce for first time an analytical model noise investigate its effect on bit error rate performance UOWC system three types waters spans. We show that, short un-clear water or longer clear water, number experiencing high, thus leading to increased The demonstrate that FEC 3×10−3 considering noise, maximum spans are 51.5, 20, 4.6 m clear, coastal, harbor waters,
