Geometric Cross-Modal Token Selection for Latency-Constrained Multimodal Token Communication
Joohyuk Park, Junyong Shin, Yongjeong Oh +2
This paper proposes a geometry-based joint cross-modal token selection framework for latency-constrained multimodal token communications. To capture cross-modal token dependencies,…
Context-Aware Wireless Token Communication via Joint Token Masking and Detection
Junyong Shin, Joohyuk Park, Yongjeong Oh +3
The increasing use of token-based representations in language-driven applications has motivated wireless token communication, where tokens are treated as fundamental units for tran…
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…
Robust Nonlinear Transform Coding: A Framework for Generalizable Joint Source-Channel Coding
Jihun Park, Junyong Shin, Jinsung Park +1
This paper proposes robust nonlinear transform coding (Robust-NTC), a generalizable digital joint source-channel coding (JSCC) framework that couples variational latent modeling wi…
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…
Unequal Error Protection for Digital Semantic Communication with Channel Coding
Seonjung Kim, Yongjeong Oh, Yongjune Kim +2
This paper investigates unequal error protection (UEP) in digital semantic communication, where semantically important bits require substantially higher reliability than less criti…
