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…
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…
Transmission Schemes based on Sum Rate Analysis in Distributed Antenna Systems
Heejin Kim, Sang-Rim Lee, Kyoung-Jae Lee +1
In this paper, we study single cell multi-user downlink distributed antenna systems (DAS) where antenna ports are geographically separated in a cell. First, we derive an expression…
