Title:
DEVICE AND METHOD FOR DECODING POLAR CODE
Document Type and Number:
WIPO Patent Application WO/2020/262775
Kind Code:
A1
Abstract:
The present invention relates to a device and a method for decoding a polar code, the device comprising: a memory for storing a received bit; a processing element for performing computation F or computation G according to a node of a received bit in the memory, wherein computation G is performed using a candidate partial sum concurrently with a pruning procedure of a special node; a metric computing unit for performing pruning to output a decoded information bit while selectively outputting a value before sorting during the pruning; and a partial sum network for computing a partial sum, computing the candidate partial sum by using the value before sorting by the metric computing unit, and outputting the computed candidate partial sum.
