Abstract
This paper provides a performance analysis of a simultaneous free-space-optics (FSO) and millimeter wave (mmWave) communication system with selection-combining and maximal-ratio-combining receivers over the <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"> <mml:mrow class="MJX-TeXAtom-ORD"> <mml:mi class="MJX-tex-caligraphic" mathvariant="script">F</mml:mi> </mml:mrow> </mml:math> -distribution channel. The <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"> <mml:mrow class="MJX-TeXAtom-ORD"> <mml:mi class="MJX-tex-caligraphic" mathvariant="script">F</mml:mi> </mml:mrow> </mml:math> -distribution model can be used to represent both the mmWave and FSO channels with proper selection of parameters. In particular, an exact-form analysis of the average bit error rate of a hybrid mmWave/FSO system is developed and substantiated through Monte Carlo simulation results, while considering varying system and channel parameters. In addition, asymptotic analysis is formulated at high, but pragmatic, signal-to-noise ratio values to elaborate further on the achieved diversity along with the impact of varying system and channel parameters. Reported results reveal that the considered hybrid system attains considerable enhancements and is promising in combating the existing challenges.
