Executive Summary

In spite of the several technical advantages of a Free Space Optical (FSO) communication, atmospheric turbulence can severely degrade the performance of a FSO link, because it creates random fluctuations in the phase and the amplitude of the received signal. The simultaneous usage of multiple transmit/receive apertures (MIMO) can mitigate the fading effects, that is particularly crucial for strong turbulent channels. However comparing to SIMO and MISO schemes, MIMO system it has more complexity and less applicability. In this paper, the authors investigate the performance of Symbol-Error-Rate (SER) and outage capacity in FSO links with Q-Ary Pulse Position Modulation (PPM) in these schemes, both in the weak and strong turbulence conditions.
