Rainbow Beamforming for Wideband LEO Satellite Communications: Principles, Applications, and Technical Challenges
Juha Park, Hyungseok Ko, Haejung Kim +4
Low Earth Orbit (LEO) satellite communications (SATCOM) has emerged as a key enabler of global connectivity for 6G networks. To overcome the significant path loss of space-to-groun…
Adversarial Water-Filling: Theory, Algorithms and Foundation Model
Xindi Tong, Chee Wei Tan, H. Vincent Poor
Competitive resource allocation problems over frequency and space can be formulated as minimax interaction between transmit power and worst-case interference. This formulation natu…
Cooperative Multi-Satellite ISAC Networks: Centralized vs. Distributed Sensing
Jeongbin Kim, Jaehong Jo, Seunghyeon Jeon +3
This paper investigates a downlink multi-satellite integrated sensing and communication (ISAC) network, in which multiple satellites simultaneously transmit ISAC signals to provide…
Embracing Beam-Squint Effects for Wideband LEO Satellite Communications: A 3D Rainbow Beamforming Approach
Juha Park, Seokho Kim, Wonjae Shin +1
Low Earth Orbit (LEO) satellite communications (SATCOM) offers high-throughput, low-latency global connectivity to a very large number of users. To accommodate this demand with lim…
Rate-Matching Framework for RSMA-Enabled Multibeam LEO Satellite Communications
Jaehyup Seong, Juha Park, Juhwan Lee +4
With the goal of ubiquitous global connectivity, multibeam low Earth orbit (LEO) satellite communication (SATCOM) has attracted significant attention in recent years. The traffic d…
