Abstract

Multiple transmitter and receivers can be used to combat link outage due to the atmosphere turbulence and scattering in an urban ´last-mile´ free space optical communication system. We investigate the use of an optical preamplifier in the resulting multiple-input-multiple-output (MIMO) system for atmospheric line-of-sight optical communication, with signal repetition across the laser array. The optically preamplified system has better performance than previous MIMO system relying on electronic amplification. Our focus is on determining symbol error probability for uncoded transmission.
