Summary: Abstract-- The term mobile FSO refers to wireless optical nodes
with mobility capabilities. Mobile FSO has emerged as a way to
combat some of limitations facing FSO links, i.e. incompatibility
of transmitters and receivers relative to movement and
misalignment. In this paper we utilize an angular diversity model
for characterizing the performance of mobile FSO over
atmospheric turbulence. Switch-and-examine combining (SEC)
technique is our suggestion for the diversity combining solution
in such unbalanced multi-transceiving configuration. The
channel fading is modeled as a lognormal distribution with
spatially correlated samples. Analytical/ statistical discussion on
the resultant output is presented and bit error performance and
processing load are numerically evaluated and compared to a
selection combining (SC) diversity.
Index Terms-- Mobile FSO, Channel state information (CSI),
Spatial diversity, Selection combining (SC), Switched diversity,
Switch-and-examine combining (SEC).
I. INTRODUCTION
Wireless optical communication, also known as free space
optics (FSO), offers advantages over Radio Frequency (RF)
