With the ever increasing spectrum demand of broadband multimedia services, cognitive
satellite terrestrial networks have emerged as a promising paradigm for future space …

The increasing demand for high-speed multimedia services and the underutilization of
scarce satellite spectral resources have recently led the researchers to propose the concept …

Cognitive satellite terrestrial networks have received considerable attention as a promising
candidate to address the spectrum scarcity problem in future wireless communications …

With great potential to support multitudinous services and applications in intelligent
transportation systems, cognitive satellite-vehicular networks, an emerging paradigm of …

We investigate the performance of a multi-beam cognitive satellite terrestrial network in
which a secondary network (mobile terrestrial system) shares resources with a primary …

The lack of available unlicensed spectrum together with the increasing spectrum demand by
multimedia applications has resulted in a spectrum scarcity problem, which affects satellite …

This paper investigates the performance of a cognitive hybrid satellite-terrestrial network,
where the primary satellite communication network and the secondary terrestrial mobile …

This letter investigates the effects of practical hardware impairments on a cognitive hybrid
satellite-terrestrial networks (CHSTN) with multiple primary users (PUs). The widely …

Due to overshadow and channel fading, many mobile users are unable to receive the signal
transmitted from satellite directly. Hence, some relay stations should be set to help this type …

Allowing frequency reuse between satellite and terrestrial networks, the integrated satellite-
terrestrial network can spatially optimize the usage of scarce spectrum resource and is thus …
