研究目的
To minimize the weighted sum transmit power for a full-duplex system with simultaneous wireless information and power transfer (SWIPT) and self-energy recycling.
研究成果
The proposed FD transmission structure with SWIPT and self-energy recycling significantly reduces the weighted sum transmit power compared to a half-duplex system. The optimal solutions obtained via SDR are proven to be equivalent to those of the original problem, validating the methodology. Simulations demonstrate the performance gains from self-energy recycling and beamforming.
研究不足
The study assumes perfect self-interference cancellation and CSI acquisition, which may not be feasible in practical scenarios. The complexity of the interior-point algorithm for solving the SDR problem is also a limitation.
1：Experimental Design and Method Selection:
The study involves designing a full-duplex point-to-point system with SWIPT and self-energy recycling, applying semidefinite relaxation to solve the non-convex optimization problem.
2：Sample Selection and Data Sources:

3：List of Experimental Equipment and Materials:
The setup includes M + N antennas at FD-AP and two antennas at FD-MS, with specific parameters for signal attenuation, noise, and energy conversion efficiency.
4：Experimental Procedures and Operational Workflow:
The methodology involves jointly designing the transmit beamforming vector, receive power splitting ratio, and transmit power value, followed by simulation to validate the analysis.
5：Data Analysis Methods:
The analysis includes comparing the performance of the proposed FD system with a half-duplex system under various SNR and energy targets, and investigating the impact of the number of transmit antennas and beamforming.
