The 5G Polar Intel® FPGA IP implements a forward error correction (FEC) encoder and decoder based on polar codes compliant with the 3rd Generation Partnership Project (3GPP) 5G specification for integration into your wireless design. Polar codes represent an emerging class of error correction supporting the high throughput requirements for 5G new radio (NR).
