Underwater Optical Wireless Communications With Optical Amplification and Spatial Diversity

This letter investigates the performance of underwater optical wireless communication (UOWC) systems employing optical pre-amplification as well as multiple receivers to exploit the advantages of spatial diversity. Numerical results are further provided to evaluate the error performance of pre-amplified single-input multiple-output UOWC systems when ON-OFF keying modulation is utilized. Our results reveal that the proposed system configuration can indeed offer significant system performance enhancements in terms of the attainable bit-error rate.
