面向6G的QC-LDPC码
QC-LDPC Codes for 6G
摘要
Abstract
In various wireless communication standards such as Wi-Fi,WiMAX,and 5G,quasi-cyclic low-density parity-check(QC-LDPC)codes are utilized as the error correction coding scheme for data channels.The decoding of QC-LDPC codes offers high parallelism,making it particularly suitable for communication systems with high data transmission rates.Although current 5G QC-LDPC codes meet peak rate requirements of up to 10 Gbps upstream and 20 Gbps downstream,they face unprecedented challenges as future 6G wireless mobile communication systems demand peak rates exceeding 100 Gbps.In response,we propose a new design for QC-LDPC codes based on iterative thresholds and a minimum distance bound,with a lifting size of up to 1024.The base matrix is compatible with 5G-BG1,allowing for compatibility with existing 5G decoding techniques.Simulation results demonstrate that the new LDPC codes offer higher decoding throughput and improved error-floor performance.关键词
