[en] Reflecting intelligent surfaces (RIS) is a low-cost
and energy-efficient solution to achieve high spectral efficiency
in sixth-generation (6G) networks. The basic idea of RIS is
to smartly reconfigure the signal propagation by using passive reflecting elements. On the other side, the demand of
high throughput geostationary (GEO) satellite communications
(SatCom) is rapidly growing to deliver broadband services in
inaccessible/insufficient covered areas of terrestrial networks.
This paper proposes a GEO SatCom network, where a satellite
transmits the signal to a ground mobile terminal using multicarrier communications. To enhance the effective gain, the signal
delivery from satellite to the ground mobile terminal is also
assisted by RIS which smartly shift the phase of the signal
towards ground terminal. We consider that RIS is mounted
on a high building and equipped with multiple re-configurable
passive elements along with smart controller. We jointly optimize
the power allocation and phase shift design to maximize the
channel capacity of the system. The joint optimization problem
is formulated as nonconvex due to coupled variables which is
hard to solve through traditional convex optimization methods.
Thus, we propose a new optimal algorithm which is based
on Mesh Adaptive Direct Search to obtain an efficient solution.
Simulation results unveil the benefits of RIS-assisted SatCom in
terms of system channel capacity.
