Abstract

Underwater wireless optical communication (UWOC) networks with high data rate demands are affected by absorption, scattering, and turbulence in aquatic environments. This work investigates polarization shift keying with linear, circular, and elliptical polarization under hybrid log-normal and Gamma–Gamma fading channels. At 10 m optical link at 520nm is simulated for clear, coastal, and turbid waters. Linear polarization achieves a Q-factor of 7.75 and bit error rate(BER) of 3.42 × 10-15 at 45°, but degrades at 90°(Q-factor = 0,BER ≈ 1), indicating high sensitivity to alignment. Elliptical polarization shows comparable performance under channel impairments, circular is moderate; BER is lowest in clear water and highest in turbid water.
