5G-NR LDPC Decoder and Encoder
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 and Encoder IP cores provide 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.
