Energy efficiency (EE) has caught more and more attention in future wireless
communications due to steadily rising energy costs and environmental concerns. In this …

This letter investigates the tradeoff between energy efficiency (EE) and spectral efficiency
(SE) in downlink multiuser distributed antenna systems (DAS). Given the SE requirement …

In this paper, we propose a transmit covariance optimization method to maximize the energy
efficiency (EE) for a single-user distributed antenna system, where both the remote access …

In this paper, we present a power allocation method for a distributed antenna system (DAS)
to maximize energy efficiency (EE), which is defined as the ratio of the transmission rate to …

In this paper, we develop an energy-efficient resource-allocation scheme with proportional
fairness for downlink multiuser orthogonal frequency-division multiplexing (OFDM) systems …

In this paper, we study energy-efficient power allocation in distributed antenna systems
(DASs). Unlike previous works that assumed perfect channel-state information (CSI) at the …

In this paper, the trade-off between energy efficiency (EE) and spectral efficiency (SE) is
analyzed for both the uplink and downlink of the distributed multiple-input multiple-output …

Spectral efficiency (SE) and energy efficiency (EE) are the main metrics for designing
wireless networks. Rather than focusing on either SE or EE separately, recent works have …

In recent years, a lot of power allocation algorithms have been proposed to maximize
spectral efficiency (SE) and energy efficiency (EE) for the distributed antenna systems …

Conventional design of wireless networks mainly focuses on system capacity and spectral
efficiency (SE). As green radio (GR) becomes an inevitable trend, energy-efficient design is …
