Russian scientists from Skoltech have created an innovative method of data coding for wireless communication systems. This approach will significantly speed up the operation of algorithms for correcting random errors that occur when transmitting data over wireless channels. The development will help improve the functioning of future sixth generation (6G) networks.
Experts have developed an improved version of low-density parity check (LDPC) codes, actively used in wireless communication systems, including modern 5G and promising 6G, to correct inevitable errors caused by interference or a weak signal.
The results of our calculations showed that after 50 iterations, the new codes show noise immunity comparable to the codes used in 5G networks, and after only ten iterations, the new approach significantly outperforms the classic 5G codes, correcting more errors in less time. This directly leads to a reduction in communication latency.
According to researchers, these algorithms effectively eliminate errors, but to achieve optimal performance, they need to perform many iterations and data processing cycles, which leads to delays and a decrease in response speed. Delays were acceptable in previous generations of networks, but the sixth generation of wireless networks requires new, faster, and more efficient error correction methods.
Russian scientists have proposed a modification of LDPC codes with more efficient decoding algorithms and alternatives to parity bits. Comparison with existing algorithms showed that the new development provides similar quality of work with higher speed and improved error correction, which will reduce delays in new generation networks.
