Περίληψη:
In the recent years, Free Space Optics (FSO) technology has attracted
significant research and commercial interest mostly because of its many
advantages in comparison with other radio systems used for
point-to-point connections. However, the reliable operation of these
systems significantly depends on the conditions of the atmosphere in the
area in which the optical beam propagates. The most important of these
conditions are atmospheric turbulence and the misalignment between the
optical beam and the receiver, which is also known as the pointing
errors effect. In this work, in order to obviate the performance
mitigation caused by these phenomena, we examined the most widely
accepted and one of the most effective techniques, i.e., the
implementation of receivers' diversity. Various metrics have been
investigated to evaluate the performance of such systems, but most of
them do not take into account that the ultra-fast modern optical
communication systems use blocks of bits for the transmission and codes
for the detection and/or correction of erroneous bits. Thus, by taking
these aspects into account, in this work, we investigated the combined
impact of spatial jitter and atmospheric turbulence on the total average
block error rate of an optical wireless system with receivers'
diversity. Novel closed-form analytical formulas were derived.
