A major performance degrading factor in free space optical communication
(FSO) systems is atmospheric turbulence. Spatial diversity techniques provide a
promising approach to mitigate turbulence-induced fading. In this paper, we
study the error rate performance of FSO links with spatial diversity over
atmospheric turbulence channels described by the Double Generalized Gamma
distribution which is a new generic statistical model covering all turbulence
conditions. We assume intensity modulation/direct detection with on-off keying
and present the BER performance of single-input multiple-output (SIMO),
multiple-input single-output (MISO) and multiple-input multiple-output (MIMO)
FSO systems over this new channel model.Comment: 6 Pages, 4 figure, IEEE ICC conference 201
