Abstract
This paper investigates the performance of a satellite-terrestrial communication system employing rate-splitting multiple access (RSMA) to accommodate multiple users. The study focuses on assessing the system’s ergodic sum rate and symbol error rate (SER) under shadowed-Rician fading conditions. By deriving closed-form expressions, we analyze the influence of various power allocation strategies on overall system performance. The results, substantiated by numerical simulations, demonstrate that RSMA yields significant improvements over conventional non-orthogonal multiple access (NOMA) with respect to spectral efficiency and interference management. These findings offer valuable insights for the development of more reliable and efficient satellite-terrestrial networks.
Simultaneous wireless information and power transfer (SWIPT) has become a key enabler for sustaining energy-constrained Internet-of-Things (IoT) devices, while simultaneous transmission and reflection reconfigurable intelligent surfaces (STAR-RIS) provide enhanced coverage and beamforming flexibility by serving users o...

In this paper, we investigate the downlink performance of multi-cell RSMA-enabled ISAC networks in which base stations (BSs), communication users, and sensing targets are spatially distributed according to independent Poisson point processes (PPPs). Each BS simultaneously serves multiple users using RSMA while exploiti...

This paper conducts the covert performance analysis of NOMA-enabled integrated satellite-terrestrial networks (ISTNs) assisted by a random-power terrestrial jammer. By adopting shadowed Rician fading for satellite-ground links and Nakagami-m fading for jammer-user links, we first analyze the eavesdropper’s binary power...
It is demonstrated that the interference-to-signal power scaling is a key factor determining TN outage behavior, with jointly scaled HAPS interference leading to interference-limited performance and RSMA provides improved outage performance compared with non-orthogonal multiple access (NOMA), particularly in the presen...

This paper investigates the outage performance of an IRS-assisted cell-free massive multiple-input multiple-output (MIMO) system for ultra-reliable low-latency communication (URLLC) scenarios. The direct and cascaded channels are modeled using Rician fading distributions, and maximum ratio transmission (MRT) precoding...
This paper proposes a fairness-oriented optimization method for free-space optical (FSO) inter-satellites laser communications based on non-orthogonal multiple access signals. The approach aims to maximize the satellite network data rate while ensuring fairness across satellite links. By considering varying distances,...
