5G-NR LDPC Decoder
5G NR is the mobile broadband standard of the 5th generation. A new rate
compatible structure for LDPC codes are employed for channel coding to
fulfill the broad applications supported by the standard. Creonic’s 5G
LDPC Decoder IP Core provides a perfect solution for this new LDPC
structure with high level of flexibility while maintaining high
throughput and low latency as required by the standard.
Applications
-
5G-NR 3GPP Rel.15 modem chipset for base station (BS) or user equipment (UE)
-
Applications with the highest demands on forward error correction
-
Applications with the need for a wide range of code rates and block length
Standard Features the Core Supports
- Support for 5G-NR LDPC decoding
- Support for base code rates from 22/68 to 22/26 for basegraph 1
- Support for base code rates from 10/52 to 10/14 for basegraph 2
- Compliant with 3GPP Release 15
