Abstract : Optical wireless communication technologies are finding a greater interest and wider attention within the research community of late. In this paper, we investigate the performance of a free space optical communication system over a generic propagation model called M-distributed channel in the presence of atmospheric turbulence. We analyzed a Subcarrier intensity-modulated free-space optical (SIM-FSO) communication system using DPSK and closed form expressions are derived using Meijer G function for bit error rate, channel capacity and outage probability for M-distribution. © 2015 Elsevier GmbH.
