Communication System Studies for the Submarine Laser Communications System

摘要

Analytical relationships between the parameters of interest to the user and the parameters characterizing the hardware and the propagation channel were established for the Submarine Laser Communications (SLC) system for the first time. These relationships constitute a useful framework to study the effects of a channel on the system performance not only for the ground- or space-based laser transmitter, but for the airborne transmitter as well. In the study, the utility of this analytical framework was demonstrated by producing a quantitative characterization of the system performance for different signal processing schemes for fading and nonfading channels. The system optimization for the strategic and tactical applications was discussed explicity in terms of means for securing minimum scanning time or maximum operational depth, respectively. (Author)
