The energy efficiency (EE) problem of a two-way decode-and-forward relay system with three nodes is studied. The maximization of the EE is done by jointly optimizing the transmission time and power of each node, assuming non-ideal power amplifiers (PAs) and considering that data to be delivered is d...
