Title: A LOW COMPLEXITY PUNCTURING METHOD FOR LOW-RATE POLAR CODES
Abstract:
Features of the present disclosure implement a low complexity rate-matching design for polar codes that supports full rate-matching granularity, in some cases without good bit re-estimation after puncturing. In particular, features of the present disclosure provide techniques for adjusting the information bits allocation based on the number of punctured bits (P) for block puncturing polar codes. Particularly, features of the present disclosure determine the number of information bits for each sector based on a capacity formula after the puncturing.
