LUCID: An Agentic AI Framework on Digital-Twin in the Loop for QoS-Guaranteeing Robotic Control
Hyeonsu Lyu, Minwoo Kim, Sehyun Ryu +1
Cloud robotics relies on the timely uplink of high-volume sensing streams, yet dynamic environments continually shift the feasible combinations of trajectories, active-robot count,…
LLM-Assisted LDPC Decoding via Syndrome-Verified Semantic Priors
Sojeong Park, Hyeonsu Lyu, Jaehyun Choi +1
Semantic communication exploits the meaning of the payload, which bit-level processing discards. When channel decoding fails on a natural language payload, the errors appear as cor…
SceneBaker: Radio-Ready Scene Generation for Sionna Ray-Tracing
Hyeonsu Lyu, Minwoo Kim, Sojeong Park +1
Wireless digital-twin (DT) research needs ray-tracing (RT) scenes that can be generated, versioned, and checked reproducibly. Current visual-authoring workflows can produce plausib…
Temporal Channel Estimation for Generalized CSI Feedback
Minwoo Kim, Hyeonsu Lyu, Sehyun Ryu +2
Efficient Channel State Information (CSI) feedback is indispensable for frequency division duplex (FDD) massive multiple-input multiple-output (MIMO) systems. Existing compressed s…
