LDPC channel encoding reduces 5G latency up to 16 times

Channel coding is used to correct transmission errors caused by noise, interference and low signal power

UK tech company AccelerComm has been focused on helping 5G meet its latency claims by providing Low Density (LDPC), Polar and Turbo Forward Error Correction parity check solutions that address challenges that would otherwise limit speed. 5G, including the error correction decoding necessary to overcome the effects of noise, interference and low signal power. And now, after more than 15 years of research that started at the University of Southampton, the company has released the 5G NR LDPC version of its error correction software, which it claims reduces latency by up to 16x .

AccelerComm CEO Tom Cronk further explained why reducing 5G latency is so critical: “For all the hype around 5G, the simple fact is that ‘ping time’ remains a problem. problem, stifling new revenue opportunities for operators of services such as games or virtual reality before they ”I had the opportunity to monetize them.

In mobile communication, channel coding or forward error correction (FEC) is used to correct transmission errors caused by noise, interference and low signal power. Unlike 3G and 4G, which use convolutional and turbo codes for control and data channels, 5G uses “much more sophisticated” Polar and LDPC codes. This change means that the industry must approach the correction of transmission errors in a completely new way. When channel coding does not work properly, mobile networks can experience poor capacity, data rates, coverage and quality of service.

Beyond reducing latency, AccelerComm claims that the software solution also results in significant energy savings for mobile networks with lower order numerology networks, and the company’s LDPC IP is optimized. and configurable to support high performance base station solutions or low power (small size) mobile terminals. solutions.

In addition, the software is fully compliant with the 3GPP NR standard for PDSCH, PUSCH and supports the full range of uncoded and encoded block sizes.

As the New Year approaches, many are wondering exactly what value 5G will really deliver. Solutions like AccelerComm’s, which reduce 5G network latency and improve capacity and coverage, can boost 5G’s chances of living up to the hype.
