Poster Abstract: Polar Code-based Approximate Communication System for Multimedia Web Pages

Polar codes have hitherto been used in the control plane of 5G-NR systems. However, in line with other contemporary works, we propose a novel use of them in the data plane by leveraging their natural property: different bit positions suffer from different degrees of errors. The idea is to map different components of web pages to different bit positions (based on their priority). We evaluate our approach for web page transmission over a wireless link that traditionally uses TCP and demonstrate benefits for image and video-based web pages. For an image-based web page, there is a 47.96% to 81.12% gain in performance, while the received image quality score varies between 0.97 and 0.99. We observe up to a 63.56% gain in performance for web pages with embedded videos with only a 7.45% loss in the received video quality.
