Abstract

Using divergent Gaussian beams mitigates the transmitter (Tx) and the receiver (Rx) misalignment in underwater optical wireless communications (UOWC) point-to-point links and increases the maximum acceptable lateral offset (MALO) at the Rx. However, extra spatial dispersion, temporal dispersion and angular spreading do occur compared to multiple scattering. Therefore, it is important to optimize the Rx for power loss, channel bandwidth and angle of arrival (AOA) distribution. Here both the field of view (FOV) and the aperture size of the Rx are investigated. We show how the required FOV of the Rx can be obtained from the AOA distribution, and also investigate how FOV and the aperture size of the Rx can be selected to minimize the power loss and the channel bandwidth degradation. To illustrate the effect of multiple scattering, results are presented for both clear and harbor waters.
