Researchers from the Skolkovo Institute of Science and Technology (Skoltech) have recently proposed an innovative Generalized Low-Density Parity-Check (GLDPC) code. This new coding scheme outperforms the existing solutions in 5G standards in terms of operating speed while maintaining the reliability of data transmission. As a new advancement in coding technology, GLDPC codes are of critical importance for advancing the design of next-generation wireless systems, particularly in reducing communication latency and ensuring reliable data transmission.

Although traditional LDPC codes can effectively detect and correct errors in data transmission, the latency caused by multiple iterations has become a barrier to their application in next-generation systems. In contrast, GLDPC codes demonstrate superior performance, with their fast convergence characteristics meaning that fewer iterations are required to achieve error correction. Addressing the challenge of high decoding complexity in GLDPC codes, the Skoltech research team proposed a new family of GLDPC codes based on the dual of the Cordaro-Wagner code and developed an efficient decoding algorithm to accompany it. The study shows that the newly proposed GLDPC codes not only match the performance of 5G standard LDPC codes at high iteration counts but also exhibit better error correction capability and faster convergence at low iteration counts.

"The research results show that the new code achieves error correction performance comparable to 5G LDPC codes at 50 iterations, while at only 10 iterations, its performance significantly surpasses that of the classic 5G codes. It can correct more errors in a shorter time, directly reducing communication latency," said Professor Alexey Frolov, Director of the Next-Generation Wireless and IoT Project Center at Skoltech. The research team is strong, including Dawit Simegn and Dmitry Artemasov, research engineers from the 6G Technology Laboratory, as well as Kirill Andreev, Assistant Professor, Pavel Rybin, Chief Research Scientist, and Professor Alexey Frolov, Head of the Next-Generation Wireless and IoT Project Center at Skoltech.
