—The use of multiple laser transmitters combined with multiple photodetectors (PDs) is studied for terrestrial , line-of-sight optical communication. The resulting multiple -input/multiple-output channel has the potential for combatting fading effects on turbulent optical channels. In this paper, the modulation format is repetition-ary PPM across lasers,(More)
—We study the use of multiple laser transmitters combined with multiple photodetectors for atmospheric, line-of-sight optical communication, and focus upon the use of multiple-pulse-position-modulation as a power-efficient transmission format, with signal repetition across the laser array. Ideal (photon counting) photodetectors are assumed, with and without(More)
The use of an optical pre-amplifler in a multiple laser multiple receive aperture system for atmospheric line-of- sight optical communications is investigated. Multiple transmit- receive paths serve to fight channel fading due to clear air scintillation. Using orthogonal polarization and repetition coding cross two lasers is shown to provide transmitter(More)
