Performance Analysis of NOMA-RIS aided Integrated Navigation and Communication (INAC) Networks

Satellite communication constitutes a promising solution for the sixth generation (6 G) wireless networks in terms of providing global services. In order to provide cost-effective satellite network, we propose novel medium-earth-orbit (MEO) aided integrated-navigation-and-communication (INAC) network. To overcome severe path loss MEO satellites, conceive network simultaneous serving navigation and ground users by adopting non-orthogonal multiple access (NOMA) technique reconfigurable intelligent surface technique. Based on power allocation strategies, communication-oriented (CO-) navigation-oriented (NO-) INAC scenarios are proposed. We first derive closed-form expressions new channel statistics, outage probability capacity INAC-user. For gleaning further insights, diversity orders accuracy evaluated illustrating performance networks. According our analysis, when RIS elements sufficient, proposed can perform better than conventional terrestrial capacity. Numerical results provided confirming that NO-INAC CO-INAC have superior low signal-to-noise-ratio (SNR) regimes high SNR regimes, respectively, which indicates hybrid CO/NO-INAC is preferable.
