We explore the performance of N-user multi-point-to-multi-point Free Space Optical (FSO) communication systems. For such systems, the communication between the N transmitters and N receivers relies on user grouping for ...

Free Space Optics (FSO) communication systems have been heavily studied in the literature during the recent decade. Compared to the widely used and traditional Radio Frequency (RF) communication systems, FSO systems are ...

Free Space Optical (FSO) channels with Multiple-Input Multiple-Output (MIMO) hops and serial relaying are studied under the e ects of Gamma-Gamma modeled atmospheric turbulence alone, and under the combined e ects of ...
