Area spectral efficiency of infrastructure relay enhanced cellular systems
( Institution of Engineering and Technology , 2016 , Article)In this study, the authors investigate the downlink area spectral efficiency (ASE) of infrastructure relay enhanced cellular systems. ASE for cellular systems is defined as the maximum achievable data rate per unit bandwidth ... -
Contract and lyapunov optimization-based load scheduling and energy management for UAV charging stations
( Institute of Electrical and Electronics Engineers Inc. , 2021 , Article)Nowadays, a large number of civilian unmanned aerial vehicles (UAVs) are increasingly being used in many of our daily applications. However, there are many kinds of UAVs that need to enhance their endurance due to their ... -
Generalized area spectral efficiency: An effective performance metric for green wireless communications
( IEEE , 2014 , Article)Area spectral efficiency (ASE) was introduced as a metric to quantify the spectral utilization efficiency of cellular systems. Unlike other performance metrics, ASE takes into account the spatial property of cellular ...
