Intellectual Property India Publishes Patent Application for Sign Bit Shaping For Polar Codes

MUMBAI, India, June 19 -- Intellectual Property India has published a patent application (202617055622 A) filed by Qualcomm Incorporated on May 01, 2026, for Sign Bit Shaping For Polar Codes.

Inventors include Wu, Liangming; Liu, Wei; Li, Jian; Jia, Yinhua; and Xu, Changlong.

The application for the patent was published on June 05, 2026, under issue no. 23/2026.

Abstract: Aspects relate to sign bit shaping for polar codes, where the shaping bits are placed on the sign bit level corresponding to a bit level with the highest reliability subchannels. Information bits and frozen bits may be placed on remaining subchannels. Each bit level may be fed to a respective polar transform (e.g., polar sub-kernel) that encodes the respective bit level...
