Nettet13. jul. 2024 · To minimize transmission power, the beamforming vectors and the IRS phase shift matrix could be optimized. One can place the IRS at preferred locations, and line-of-sight (LoS) can be adopted for ... Nettet3. aug. 2013 · The problem of joint beamforming and power allocation for cognitive multi-input multi-output systems is studied via game theory. The objective is to maximize the sum utility of secondary users (SUs) subject to the primary user (PU) interference constraint, the transmission power constraint of SUs, and the signal-to-interference …

Joint Hybrid Beamforming and User Scheduling for Multi-Satellite ...
NettetWe consider a multiple-input multiple-output amplify-and-forward wireless multiple-hop sensor network (WMSN). The simultaneous wireless information and power transfer technology is deployed to potentially achieve an autonomous system. We investigate two practical receiver schemes, which are the power splitting (PS) and the time switching … Nettet3. jan. 2024 · The joint beamforming design is formulated as a non-convex optimization problem for striking a compelling trade-off amongst the conflicting design objectives of radar transmit beampattern, communication quality of service (QoS), and the PLS level. Nettet10. jan. 2024 · Joint Hybrid Beamforming and User Scheduling for Multi-Satellite Cooperative Networks. Xuan Zhang, Shu Sun, Meixia Tao, Qin Huang, Xiaohu Tang.
