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.enginfo:eu-repo/semantics/restrictedAccessConference paper5144514900037170810506210.1109/ICC.2015.7249140Atmospheric turbulenceDouble GG distributionFree-space optical systemsMIMOBit error rateError rate performance analysisSpatial diversity2-s2.0-84953745853
