Channel coding software speeds up edge networks, reduces latency

AccelerComm announced it has developed a highly optimized LDPC software decoder in collaboration with Intel.

The solution is integrated into the Intel’s FlexRAN Reference Software resulting in increased throughput by up to 3 times over alternate implementations, according to the companies. The LDPC decoder benefits from a combination of optimized architectural and algorithmic enhancements and use of the powerful Intel Architecture and Intel Advanced Vector Instructions 512 (Intel AVX512) instruction sets.

The AccelerComm LDPC implementation takes advantage of these capabilities on Intel Xeon Scalable processor and with fewer cores delivers performance within 0.1 dB of Intel’s SDK module. FlexRAN is a reference architecture developed by Intel to implement virtualised Radio Access Networks which can be deployed on any part of the wireless infrastructure from edge to core. The LDPC software decoder can operate as an upgrade to FlexRAN or standalone and is available directly from AccelerComm.

Channel coding, also known as forward error correction, is used to correct transmission errors in mobile communications caused by noise, interference and poor signal strength. While 3G and 4G used Convolutional and Turbo codes for the control and data channels, 5G uses the much more sophisticated Polar and LDPC codes and requires the industry to look afresh at how to address error correction. An evaluation version of an optimised LDPC decoder for FlexRAN is available now to download at
