The cognitive hybrid satellite terrestrial networks (CHSTN) is regarded as an effective way to
enhance the spectrum efficiency as well as mitigate the spectrum scarcity problem. In this …

With the increasing requirements for efficient utilization of satellite resources, both non-
orthogonal multiple access (NOMA) scheme and cognitive radio (CR) have been recognized …

Satellite communication has become a popular study topic owing to its inherent advantages
of high capacity, large coverage, and no terrain restrictions. Also, it can be combined with …

Satellite communication has attracted great interests due to extensive coverage and no
terrain restriction, which can make up for the shortcomings of terrestrial communication …

Satellite-terrestrial networks (STNs) have received significant attention from research and
industry due to their capability of providing a stable connection to rural and distant areas …

In the paper, we present a study on the performance analysis of a non-orthogonal multiple
access (NOMA) underlay cognitive hybrid satellite-terrestrial relaying network (CSTRN) and …

In this article, we investigate the performance of spectrum sharing inunderlay cognitive radio
(CR)-inspired nonorthogonal multiple access (NOMA) systems, at which a primary …

In this paper, a downlink scenario of a non-orthogonal multiple access (NOMA) scheme with
power constraint via spectrum sensing is considered. Such network provides improved …

In this paper, we investigate the performance of non-orthogonal multiple access (NOMA)-
based overlay cognitive integrated satellite-terrestrial relay network with secondary network …

In this paper, a hybrid satellite-terrestrial spectrum sharing system allows terrestrial
secondary network to cooperate with a primary satellite network and to further provide …
