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.
