This paper investigates the performance of underwater visible light communications (UVLC) systems employing multiple transmitters and/or multiple receivers to exploit the advantage of spatial diversity. Experimental results are further provided to evaluate the error performance of single input multiple outputs (SIMO), multiple inputs single output (MISO) and multiple inputs multiple outputs (MIMO)...
The effect of fiber nonlinearity on orthogonal frequency division multiplexing passive optical network (OFDM-PON) is investigated. The simulation and experiment demonstrations show that the fiber nonlinearity would cause energy transfer from the optical carrier to the OFDM sidebands and distorts the OFDM signal, which change the carrier to signal power ratio (CSPR) and the performance of the receiver...
Polarization-interleaved OFDM-PON with double sideband modulation is presented for high speed next generation optical access network. 40-Gb/s OFDM-PON based on polarization interleaving and double sideband is experimentally demonstrated.
We investigate the restriction of double-sideband (DSB) transmission for a next-generation orthogonal frequency division multiplexing passive optical network (OFDM-PON). First, the power fading induced by chromatic dispersion is well described for DSB OFDM signals. Then we show by simulation and experiment that the power fading effect can be made negligible for an access network by employment of high-order...
