In this paper, we experimentally demonstrate wireless transmission of optical intensity modulation/direct detection-orthogonal frequency division multiplexing (IM/DD-OFDM) signals in an underwater channel using a field programmable gate array based real-time transmitter. The real-time transmission of a 405 nm 1.45 Gbit/s optical OFDM signal through a 4.8 m underwater channel with an error vector magnitude of approximately 10% was successfully achieved.
在本文中，我们通过基于现场可编程门阵列的实时发射机，在水下信道中对光强度调制/直接检测正交频分复用（IM/DD-OFDM）信号进行了无线传输实验演示。成功实现了405纳米、1.45吉比特/秒的光OFDM信号在4.8米水下信道中的实时传输，误码向量幅度约为10%。
