Abstract

The performance of maximum-ratio combining for free-space optical systems using heterodyne detection is analytically studied. The analysis includes the joint effect of turbulence- and misalignment-induced channel fading. Particularly, novel closed-form expressions regarding the scintillation index, outage probability and average bit-error rate are derived. Based on these results, some useful outcomes are manifested, such as the system diversity order, the crucial role of diversity branches, and the impact of composite channel fading onto the system performance.
