LDPC Encoder/Decoder
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
Your Benefits
- High throughput
