On Performance of Integrated Satellite HAPS Ground Communication: Aerial IRS Node vs Terrestrial IRS Node
With a motive of ubiquitous connectivity over the globe with enhanced
spectral efficiency, intelligent reflecting surfaces (IRS) integrated
satellite-terrestrial communications is a topic of research interest in an
infrastructure-deficient remote terrains. In line with this vision, this paper
entails the performance analysis of satellite-terrestrial networks leveraging
both aerial and terrestrial IRS nodes, with the support of high altitude
platforms over diverse fading channels including shadowed Rician, Rician, and
Nakagami- fading channels. The merits of IRS in enhancing spectral
efficiency is analyzed through closed-form expressions of outage probability
and ergodic rate. Further, the average symbol error rate analysis for the
higher-order quadrature amplitude modulation (QAM) schemes such as hexagonal
QAM, rectangular QAM, cross QAM, and square QAM is performed. Practical
constraints like antenna gains, path loss, and link fading are considered to
characterize the satellite terrestrial links. Finally, a comparison between the
high-altitude platforms based IRS node and terrestrial IRS nodes is performed
and various insights are drawn under various fading scenarios and path loss
conditions. This paper contribute towards understanding and potential
implementation of IRS-integrated satellite-terrestrial networks for efficient
and reliable communication
