Abstract

Technical specification of 5G New Radio uses QC-LDPC code as forward error correction coding scheme in data channel for eMBB scenario. The specification gives tough requirements of performance, latency and throughput in addition to code rate flexibility. In this paper we propose a modified parallel layered decoder architecture that is able to support all the mentioned in-standard codeblock lengths in a natural and extendible way. Also we provide estimates on the hardware resources consumption and decoder throughput.
