A High-Throughput Multi-Mode LDPC Decoder for 5G NR

A High-Throughput Multi-Mode LDPC Decoder for 5G NR

This paper presents a partially parallel low-density parity-check (LDPC) decoder designed for the 5G New Radio (NR) standard. The design is using a multi-block parallel architecture with a flooding schedule. The decoder can support any code rates and code lengths up to the lifting size Zmax= 96. To...

Zusammenfassung:This paper presents a partially parallel low-density parity-check (LDPC) decoder designed for the 5G New Radio (NR) standard. The design is using a multi-block parallel architecture with a flooding schedule. The decoder can support any code rates and code lengths up to the lifting size Zmax= 96. To compensate for the dropped throughput associated with the smaller Z values, the design can double and quadruple its parallelism when lifting sizes Z
