为了提高室内电力线通信和可见光通信(PLC-VLC)系统的吞吐量和用户体验的公平性,该文提出一种改进遗传算法优化用户配对联合子载波分配(IGA-JUPSA)方法.在IGA-JUPSA的用户配对阶段,设计了最优的非正交多址技术(NOMA)用户配对方法,提高PLC-VLC系统的吞吐量;在IGA-JUPSA的子载波分配阶段,设计NOMA与正交多址技术结合的子载波分配策略,设计改进的遗传算法优化不同NOMA组的子载波分配,提高系统的吞吐量和用户体验的公平性.仿真结果表明,所提的用户配对和子载波联合方法可以提高PLC-VLC系统的吞吐量和用户体验的公平性. |

For improving the throughput and the fairness of user experience of indoor power line communications-visible light communications (PLC-VLC) system, an improved genetic algorithm based joint user pairing and subcarrier allocation (IGA-JUPSA) method is proposed in the paper. In the user pairing stage, a method of optimal non-orthogonal multiple access (NOMA) user pairing is designed to improve the throughput of PLC-VLC system. During the process of subcarrier allocation, the subcarrier allocation scheme combined NOMA with orthogonal multiple access (OMA) is proposed, and the improved genetic algorithm is used to optimize the subcarrier allocation for different NOMA groups for improving the system throughput and user fairness. Simulation results show that the proposed IGA-JUPSA can improve the throughput of PLC-VLC cascaded system and the fairness experience of users. |
