面向6G的高效率QC-LDPC码设计
High-Efficiency Quasi-Cyclic Low-Density Parity-Check Code Design for 6G
摘要
Abstract
Quasi-cyclic low-density parity-check(QC-LDPC)codes have been widely adopted as forward error correction schemes for data channels in wireless communication systems.Due to their structured construction and suitability for highly parallel decoding,QC-LDPC codes are particularly advantageous for high data rate transmission.However,sixth-generation(6G)communications impose stringent requirements on ultra-high data rates and energy efficiency.Existing fifth-generation low-density parity-check codes suffer from slow decoding convergence,resulting in high computational complexity and power consumption.To address this issue,a high-efficiency QC-LDPC code design for 6G is proposed.By reducing the number of edges in the parity-check matrix and accelerating the convergence of iterative decoding,the proposed scheme achieves reduced decoding complexity while maintaining decoding performance.As a result,an improved trade-off between performance and computational complexity is achieved.关键词
