Dynamic Energy Harvesting Based Semidefinite Relaxation Beamforming Optimization for Near-Field SWIPT in IoT Networks

This paper proposes a dynamic power splitting for near-field simultaneous wireless information and power transfer (SWIPT) using semidefinite relaxation (SDR) for efficient energy harvesting (D-SR-EH) in energy-constrained internet of things (IoT) networks. The near-field spherical propagation beamforming design is form...

On the Performance of Quantum Approximate Optimization-Based User Grouping for Rate-Splitting Multiple Access

This letter investigates quantum approximate optimization algorithm (QAOA)-based user grouping for clustered rate-splitting multiple access (RSMA) with imperfect channel state information (CSI). In each local group, one common stream and multiple private streams are jointly transmitted. Hence, the grouping decision det...
