Software Implementation of 5G NR Downlink Polar Encoders
Giyoon Park, Nam-Il Kim · 2022 13th International Conference on Information and Communication Technology Convergence (ICTC) · 2022
In this paper, we present software implementations of 5G NR downlink physical control channels encoders, which is based on binary polar codes. The transport formats of control channels are limited and the implementations are tuned to the formats. Also the software routines are written in advanced vector extensions instructions for processing multiple data at once. The effectiveness is demonstrated by processing time measurements on general purpose computers.
