LDPC Intel® FPGA IP

5G Low-Density Parity-Check

Low-density parity-check (LDPC) codes are linear error correction codes that allow you to transmit messages over noisy channels. Intel's 5G Low-Density Parity Check (LDPC) Intel FPGA Intellectual Property (IP) core is a high-throughput encoder or decoder that is compliant with 3rd Generation Partnership Project (3GPP) 5G specification. LDPC codes offer better spectral efficiency and support the high throughput for 5G new radio (NR). With the flexibility of Intel FPGAs, various configurations can be designed and implemented and re-designed to support any changes to base graph, code rate, Z and LR width.
