Random Beam-Based Non-Orthogonal Multiple Access for Massive MIMO Low Earth Orbit Satellite Networks

Abstract: In this paper, we propose random beam-based non-orthogonal multiple access (NOMA) for massive multiple-input multiple-output (MIMO) low earth orbit (LEO) satellite communication systems that ...

Unsourced Random Access Using Transformer over Massive MIMO Time-variant Channels

Abstract: This paper proposes a novel unsourced random access scheme that can consider relative movement between devices and a single base station, which is essentially different from conventional ...
