Abstract

In this paper, we consider a free-space optical (FSO) communication with multiple receive apertures over -distributed turbulence channels with pointing errors. In particular, we consider two different combining schemes at the receiver: optimal combining (OC) and selection combining (SC). With these setups, the statistic characters of the instantaneous electrical signal-to-noise ratio (SNR) are derived. Then, using the cumulative density function (CDF)-based method, we analyze the asymptotic bit-error rate (BER) performance. The derived results help quantifying the diversity order of our considered systems.
