Multi-Domain Iterative Detection for Massive Connectivity in LEO Satellite Networks
Xinhua Liu, Yueqing Wang, Keke Ying, Peihu Duan, Dapeng Li, Ziwei Wan, et al.
Grant-Free (GF) random access is promising for low Earth orbit satellite Internet due to its reduced access latency. However, existing schemes suffer from poor performance in massive connectivity scenarios. To address this challenge, we firstly propose an iterative residual feedb…
