Abstract
In this chapter, we study multiple-input multiple-output (MIMO) free-space optical (FSO) communication systems degraded by atmospheric turbulence, absorption, scattering, diffraction, and misalignment. The employment of multiple transmit/receive apertures are studied as a means to enhance the reliability of FSO links by combating atmospheric turbulence through the insertion of redundancy (i.e. spatial diversity). The fundamental differences between RF and optical wireless MIMO channels are discussed and the most recent results reported for different channel models are presented. We further extend our investigation to include some important results on distributed MIMO FSO systems.
