PRIYADARSHANI, R., et al. On Optically Pre-amplified FSO-MISO Non-identical Links with Correlation: Experiment and Analysis. In: 2019 IEEE Global Communications Conference (GLOBECOM) - Proceedings. IEEE Global Communications Conference 2019, Waikoloa, HI, 2019-12-09/2019-12-13. San Francisco: American Institute of Physics and Magnetic Society of the IEEE, 2019. p. 1-6. ISSN 2576-6813.

In this paper, various link characteristics and bit
error rate (BER) performance of a free-space optical (FSO)
multiple-input-single-output (MISO) system with repetition cod-
ing (RC) is investigated both experimentally and theoretically.
The study is performed in the presence of atmospheric turbulence
(AT) over a correlated channel with an erbium-doped fiber am-
plifier employed at the receiver (Rx). It is shown experimentally
that the measured AT levels of two parallel links are different and
the links experience non-identical fading influence. The analytical
BER expression for an optically pre-amplified correlated FSO-
MISO system with non-identical AT channel is derived. The BER
results of the considered system with pre-amplifier is compared
with the BER results of an FSO system without pre-amplifier, and
it is shown analytically that a 2×1 FSO system with pre-amplifier
offers better BER performance in terms of coding gain of 6
dB over the system without pre-amplifier. Moreover, it is also
shown that the FSO system with RC gives better performance
with identical links as compared to non-identical links. Further, it
is also revealed that the diversity order of the considered system
is independent of correlation and use of pre-amplifier. All the
analytical results are validated by comparing them with Matlab
simulations.
