The performance differences are investigated for terrestrial relay-assisted Integrated Satellite-Terrestrial Networks (ISTNs) when satellite employs different decoding schemes. Initially; a multi-user pairing scheme leveraging location information is proposed; and multiple users within the coverage area of satellite beam are divided into several groups. To improve transmission reliability and spectral efficiency; users communicate with satellite employing hybrid multiple access. Additionally; assuming that user-terrestrial relay links obey Nakagami-m fading while terrestrial relay-satellite link follows correlated shadowed-Rician fading; the closed-form expressions of outage probability and throughput are derived when the satellite adopts Successive Interference Cancellation (SIC) and Joint Decoding (JD) respectively. Finally; computer simulations validate the correctness of the theoretical analysis and the superiority of the proposed scheme compared with Orthogonal Multiple Access (OMA); and reveal that JD decoding scheme is feasible in the ISTNs. © 2024 Science Press.
