Abstract

In this paper, we analyze the performance of the cooperative optical wireless communication (OWC) systems under the effect of atmospheric turbulence. We consider a dual-hop OWC system having a relay-assisted link between source and destination using a decode and forward (DF) relaying protocol. The atmospheric turbulence channels are modeled by independent but not necessarily identically distributed (i.n.i.d) gamma-gamma fading statistics. The exact closed form expressions of outage probability and average bit-error rate (BER) are derived using the power series representations of the modified bessel function of second kind and illustrated through numerical plots.
