摘要

In this letter, we propose and experimentally demonstrate an underwater wireless optical communication system based on a simple and cost-effective TO56 transversal multi-mode green-light laser diode (LD) and a low-cost 150-MHz positive-intrinsic-negative detector. We use quadrature amplitude modulation (QAM)-orthogonal frequency-division multiplexing modulation, with fine frequency granularity and...
