Optical wireless links with spatial diversity over strong atmospheric turbulence channels
TL;DR: This paper investigates the error rate performance of FSO systems for K-distributed atmospheric turbulence channels and discusses potential advantages of spatial diversity deployments at the transmitter and/or receiver, and presents efficient approximated closed-form expressions for the average bit-error rate (BER) of single-input multiple-output (SIMO) FSO Systems.
