Turbo Intel® FPGA IP

Forward-error correction (FEC) channel codes commonly improve the energy efficiency of wireless communication systems. Turbo codes are suitable for 3G and 4G mobile communications and satellite communications. You can use Turbo codes in other applications that require reliable information transfer over bandwidth- or latency-constrained communication links in the presence of data-corrupting noise. The 4G Turbo-V Intel® FPGA IP comprises a downlink and uplink accelerator for vRAN and includes the Turbo Intel® FPGA IP.
