Title:
POLARIZATION WEIGHT CALCULATION FOR PUNCTURED POLAR CODE
Document Type and Number:
WIPO Patent Application WO/2018/149416
Kind Code:
A1
Abstract:
Techniques are described for wireless communication. One method includes identifying a set of punctured bit locations in a received codeword. The received codeword is encoded using a polar code. The method also includes identifying a set of information bit locations of the polar code, with the set of information bit locations being determined based at least in part on polarization weights per polarized bit-channel of a polar code decoder that are a function of nulled repetition operations per polarization stage of the polar code identified based at least in part on the set of punctured bit locations. The method further includes processing the received codeword using the polar code decoder to obtain an information bit vector at the set of information bit locations.
