Abstract

This work presents results pertinent to the study of spatial diversity as a means for partially overcoming the deleterious effects of the clear-air turbulent atmosphere on direct detection and heterodyne optical communication systems. For photon counting receivers, an averaged threshold receiver is presented, which is seen to be simpler to implement and to provide consistently lower bit error rates than optimized memoryless receivers. The heterodyne results include the introduction of a partial tracking heterodyne array; a discussion, both theoretical and experimental, of IF signal magnitude probability distributions for static heterodyne arrays; and a theoretical treatment of the probability distribution for a single heterodyne element with angle-of-arrival tracking.
