Original title: TokenComSR: Task-Sensitivity-Guided Token Communication for Wireless Image Super-Resolution
Ye Wang, Li Qiao, Zhen Gao, Hua Wang · September 2026
Sending images from small wireless devices over weak connections is difficult. Traditional methods fail abruptly when the signal drops, while standard neural network approaches struggle to protect small image patches. To solve this, researchers designed a system called TokenComSR. It breaks images into smaller visual pieces called tokens. First, a power allocation tool figures out which image pieces are most critical for sharpness and gives them extra transmission power. Next, a refinement tool checks channel noise and cleans up transmission errors in these tokens before decoding. Finally, a receiver rebuilds and sharpens the image to a higher resolution. Testing showed that this approach effectively protects images, beating older separate coding and existing neural network baselines in both detail accuracy and visual quality.
Imagine you're sending a postcard with a drawing, but the mail service is unreliable. If some parts of the drawing are critical, like a face, you'd want to make sure those parts arrive intact. In this paper, the system is like sending each part of the drawing with extra care based on its importance, and then fixing any smudges on arrival before putting it together.
When you send images over weak wireless signals, like on a phone in a bad area, the picture often breaks completely. This framework keeps images clear by sending important parts more reliably, helping people on low-power devices get better quality without extra data.
The abstract does not specify real-world deployment constraints or performance under diverse channel conditions beyond simulations. It focuses on resource-constrained scenarios but does not address scalability or computational overhead.
