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…
End-to-End Secure Connection Probability in MultiLayer Networks with Heterogeneous Rician Fading
Hyeonsu Lyu, Yumin Kim, Hyun Jong Yang
Ensuring physical-layer security in non-terrestrial networks (NTNs) is challenging due to their global coverage and multi-hop relaying across heterogeneous network layers, where th…
Accuracy-Delay Trade-Off in LLM Offloading via Token-Level Uncertainty
Yumin Kim, Hyeonsu Lyu, Minjae Lee +1
Large language models (LLMs) offer significant potential for intelligent mobile services but are computationally intensive for resource-constrained devices. Mobile edge computing (…
Faithful and Fast Influence Function via Advanced Sampling
Jungyeon Koh, Hyeonsu Lyu, Jonggyu Jang +1
How can we explain the influence of training data on black-box models? Influence functions (IFs) offer a post-hoc solution by utilizing gradients and Hessians. However, computing t…
