Saturation Power based Simple Energy Efficiency Maximization Schemes for MU-MISO Systems
Jaehoon Jung, Sang-Rim Lee, Inkyu Lee
In this paper, we investigate an energy efficiency (EE) maximization problem in multi-user multiple input single output downlink channels. The optimization problem in this system m…
Resource Allocation Techniques for Wireless Powered Communication Networks with Energy Storage Constraint
Hoon Lee, Kyoung-Jae Lee, Hanjin Kim +2
This paper studies multi-user wireless powered communication networks, where energy constrained users charge their energy storages by scavenging energy of the radio frequency signa…
A New Energy Efficient Beamforming Strategy for MISO Interfering Broadcast Channels based on Large Systems Analysis
Sang-Rim Lee, Jaehoon Jung, Haewook Park +1
In this paper, we propose a new beamforming design to maximize energy efficiency (EE) for multiple input single output interfering broadcast channels (IFBC). Under this model, the…
Joint Subcarrier and Power Allocation Methods in Wireless Powered Communication Network for OFDM systems
Hanjin Kim, Hoon Lee, Minki Ahn +2
In this paper, we investigate wireless powered communication network for OFDM systems, where a hybrid access point (H-AP) broadcasts energy signals to users in the downlink, and th…
