面向6G的高效率QC-LDPC码设计OA
High-Efficiency Quasi-Cyclic Low-Density Parity-Check Code Design for 6G
在各类无线移动通信中,QC-LDPC(Quasi-Cyclic Low-Density Parity-Check)码被广泛用作数据信道的前向纠错编码方案.由于其结构规则且易于实现高并行译码,QC-LDPC码特别适用于高数据速率传输.然而,6G通信要求超高的数据速率与超高的能效,而现有5G LDPC码存在译码收敛速度较慢问题,从而导致其译码的计算复杂度高并且功耗较大.因此,提出一种面向6G的高效率QC-LDPC码设计.通过减少LDPC译码的奇偶校验矩阵的边数并且提升迭代译码的收敛速度,所提出的方案能够在保持译码性能的同时降低LDPC译码的计算复杂度,从而可以在性能与复杂度之间实现最佳平衡.
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.
