摘要

利用智能反射面（IRS），利用能够反射相移可调信号的大量低成本无源元件，实现高无源波束成形增益，从而显著提高同步无线信息与功率传输（SWIPT）系统的信息传输效率和速率能量平衡。针对多天线接入点（AP）服务于多信息解码接收机（IDRs）和能量收集接收机（EHRs）的问题，提出了一种IRS辅助多天线接入点（AP）的方法。为了解决IRS技术辅助下SWIPT系统中电子病历接收加权和功率和IDRs和速率的多目标优化问题，提出了量子沙猫群优化算法（QSCSO）。从量子启发的群体智能出发，借助量子计算设计了一种新的机制，即量子沙猫借助量子旋转门来改善最优行为。在我们的IRS辅助SWIPT系统中，为了平衡能量收集和信息传输，通过共同分配IRS处的反射相移和AP处的发射预编码器，利用新提出的QSCSO，同时最大化了idr的和速率和ehr接收的加权和功率。实验结果表明，与传统的优化算法相比，该算法显著提高了irs辅助下SWIPT系统的idr和率和ehr接收加权和功率。

Multi-objective joint resource allocation for IRS-assisted SWIPT System with Quantum Sand Cat Swarm Optimization

Through utilizing intelligent reflecting surface (IRS), high passive beamforming gain can be achieved by utilizing massive low-cost passive components capable of reflecting signals with adjustable phase shifts, and thus significantly improve information transmission efficiency and rate energy balance of simultaneous wireless information and power transfer (SWIPT) system. Aiming at providing service to multiple information decoding receivers (IDRs) and energy harvesting receivers (EHRs), multiple-antenna access point (AP) is assisted by IRS in this paper. To solve the multi-objective optimization of received weighted sum-power of EHRs and sum-rate of IDRs in SWIPT system assisted by IRS technology, we have proposed quantum sand cat swarm optimization algorithm (QSCSO). Derived from quantum-inspired swarm intelligence, a novel mechanism is newly designed by the aid of quantum computing that is quantum sand cats improve the optimal behavior with the help of quantum rotation gate. In our IRS-assisted SWIPT system, to balance between energy harvesting and information transmission, through jointly allocation of reflect phase shifts at IRS and transmit precoders at AP, the sum-rate of IDRs and weighted sum-power of EHRs reception are simultaneously maximized by utilizing the newly proposed QSCSO. Through the newly proposed algorithm, the sum-rate of IDRs and weighted sum-power of EHRs reception are significantly improved in IRS-assisted SWIPT system based on experimental results compared with previous traditional optimization algorithms.
