SemABR: Measuring Video Semantic Fidelity with Multimodal LLMs for Adaptive Bitrate Streaming
Shiqi Xu, Soung Chang Liew, Yuyang Du
Conventional video metrics such as PSNR, SSIM, and VMAF measure visual distortion or perceptual quality, but they do not directly capture semantic preservation: whether compression…
Broadcast Rate Limits in Wi-Fi: A Forgotten Bottleneck for Collaborative Edge LLM Inference
Liujianfu Wang, Yuyang Du, Shiqi Xu +1
LLM deployment is migrating from data centers to edge devices, where Mixture-of-Experts (MoE) models offer a promising path: sparse expert activation allows the model to be spread…
Real-Time Cross-Layer Semantic Error Correction Using Language Models and Software-Defined Radio
Yuchen Pan, Yuyang Du, Yirun Wang +3
As Language Models (LMs) advance, Semantic Error Correction (SEC) has emerged as a promising approach for reliable network designs. Yet existing methods prioritize intent over accu…
LightGuard: Transparent WiFi Security via Physical-Layer LiFi Key Bootstrapping
Shiqi Xu, Yuyang Du, Mingyue Zhang +2
WiFi is inherently vulnerable to eavesdropping because RF signals may penetrate many physical boundaries, such as walls and floors. LiFi, by contrast, is an optical method confined…
A Hybrid TDMA/CSMA Protocol for Time-Sensitive Traffic in Robot Applications
Shiqi Xu, Lihao Zhang, Yuyang Du +2
Recent progress in robotics has underscored the demand for real-time control in applications such as manufacturing, healthcare, and autonomous systems, where the timely delivery of…
IndusGCC: A Data Benchmark and Evaluation Framework for GUI-Based General Computer Control in Industrial Automation
Xiaoran Yang, Yuyang Du, Kexin Chen +14
As Industry 4.0 progresses, flexible manufacturing has become a cornerstone of modern industrial systems, with equipment automation playing a pivotal role. However, existing contro…
Nonlinear Multi-Carrier System with Signal Clipping: Measurement, Analysis, and Optimization
Yuyang Du, Liang Hao, Yiming Lei +2
Signal clipping is a classic technique for reducing peak-to-average power ratio (PAPR) in orthogonal frequency division multiplexing (OFDM) systems. It has been widely applied in c…
