After 15 years of research that first began at the University of Southampton, AccelerComm Ltd, a University of Southampton spin-off, has announced the general availability of its 5G NR low-density parity-check (LDPC) version of its error correction software. This software reduces latency up to 16x to support numerology 4 in 3GPP 38.211 and also results in power savings for mobile networks with lower-order numerology networks.
Helping 5G Achieve its Latency Claims
AccelerComm has been focused on helping 5G achieve its low latency claims by providing LDPC, polar, and turbo forward error correction solutions that address challenges that would limit the speed of 5G, notable error correction decoding that is necessary to overcome noise, interference, and poor signal strength.
In mobile communication, forward error correction (FEC) is used to correct transmission errors that are caused by the above. Unlike 3G and 4G, which use convolutional and turbo codes, 5G uses polar and LDPC codes. This change means that the industry must approach error correction in a new way. When channel coding does not work as intended, networks can experience poor coverage, quality of service, and data rates.
AccelerComm claims that their software solution does more beyond latency reduction, such as a significant boost in power savings for mobile networks with lower-order numerology. The company’s LDPC IP is also optimized and configurable to support high-performance base station solutions or low power mobile terminal solutions.
3GPP Standards Complaint
The software is fully compliant with the 3GPP NR standard for PDSCH, PUSCH, and also supports a full range of uncoded and encoded block sizes. It implements the entire LDPC encoding and decoding chain in 3GPP TS38.212 with superior error correction performance and hardware efficiency.
AccelerComm CEO, Tom Cronk, commented, “For all the hype around 5G, the simple fact is ‘ping time’ remains an issue, stifling new revenue opportunities for operators from services such as gaming or VR before they’ve had an opportunity to monetise them. After more than 15 years of research by the team, first at the University of Southampton and now at AccelerComm, we’re able to deliver on the 5G promise of a low latency, high throughput experience.”
AccelerComm’s solutions are 3GPP standards-compliant and cover the full processing chain.
