Open AccessEnergy-efficiency maximization bidirectional direct and relay transmission
Energy-efficient transmission (EET) has become a very important problem in wireless communication. Optimal power allocation (OPA) is one of the general methods to achieve EET. But when OPA is only considered i...

Open AccessAdaptive wireless transmission strategy for maximizing energy efficiency
In a traditional wireless transmission system, studies about energy efficiency (EE) are usually for a fixed transmission mode. In this paper, we propose an adaptive wireless transmission (AWT) strategy with co...
