Stochastic Design of Active RIS-Assisted Satellite Downlinks under Interference, Folded Noise, and EIRP Constraints
Muhammad Khalil, Ke Wang, Jinho Choi
Active reconfigurable intelligent surfaces (RISs) can mitigate the double-fading loss of passive reflection in satellite downlinks. However, their gains are limited by random co-ch…

Towards Optimal Semantic Communications: Reconsidering the Role of Semantic Feature Channels
Yongjeong Oh, Jihong Park, Jinho Choi +1
This paper investigates the optimization of transmitting the encoder outputs, termed semantic features (SFs), in semantic communication (SC). We begin by modeling the entire commun…
