N2 - In the work, we carry out a unified performance
analysis of a dual-hop fixed gain relay system over asymmetric
links composed of both radio-frequency (RF) and unified free-
space optics (FSO) under the effect of pointing errors. The
RF link is modeled by the Nakagami-m fading channel and
the FSO link by the Gamma-Gamma fading channel subject
to both types of detection techniques (i.e. heterodyne detection
and intensity modulation with direct detection (IM/DD)). In
particular, we derive new unified closed-form expressions for the
cumulative distribution function, the probability density function,
the moment generation function, and the moments of the end-to-end
signal-to-noise ratio of these systems in terms of the Meijer’s
G function. Based on these formulas, we offer exact closed-form
expressions for the outage probability, the higher-order amount
of fading, and the average bit-error rate of a variety of binary
modulations in terms of the Meijer’s G function. Further, an
exact closed-form expression for the end-to-end ergodic capacity
for the Nakagami-m-unified FSO relay links is derived in terms
of the bivariate G function. All the given results are verified via
Computer-based Monte-Carlo simulations.
