KKTCode: Asymptotically Optimal Linear Codes for Noisy Feedback AWGN Channels
Hongjae Nam, Jonggyu Jang, Vishrant Tripathi +1
The design of optimal causal linear feedback schemes for additive white Gaussian noise (AWGN) channels with noisy output feedback has remained an open problem for over 60 years. Pr…
MaskCode: Mask Transformer for Feedback-Assisted Coding With Linear Block Codes
Jonggyu Jang, Hongjae Nam, Vishrant Tripathi +2
Feedback-based coding schemes have demonstrated substantial performance gains over today's open-loop coding schemes. Unfortunately, these gains are usually achieved in idealized se…
Optimizing Information Freshness for Wireless Local Area Networks with Multiple APs
Ananth Ram Rajagopalan, Jiahui Ni, Vishrant Tripathi
Dense indoor WLANs increasingly rely on multiple access points (APs) operating over partially overlapping spectrum to support latency-sensitive applications. In such deployments, s…
Communication-Efficient Personalized Adaptation via Federated-Local Model Merging
Yinan Zou, Md Kamran Chowdhury Shisher, Christopher G. Brinton +1
Parameter-efficient fine-tuning methods, such as LoRA, offer a practical way to adapt large vision and language models to client tasks. However, this becomes particularly challengi…
Exploring Performance Tradeoffs in Age-Aware Remote Monitoring with Satellites
Sunjung Kang, Vishrant Tripathi, Christopher G. Brinton
We investigate a remote monitoring framework with multiple sensing modalities including IoT sensors on the ground, mobile UAVs in the air, and a periodically available satellite co…
Using Age of Information for Throughput Optimal Spectrum Sharing
Hongjae Nam, Vishrant Tripathi, David J. Love
We consider a spectrum sharing problem where two users attempt to communicate over N channels. The Primary User (PU) has prioritized transmissions and its occupancy on each channel…
