In this letter, we investigate the tradeoff between energy efficiency (EE) and spectral efficiency (SE) in the Uplink of Distributed Antenna Systems with uniformly distributed Uts over the MIMO Rayleigh Fading Channel, and then demonstrate the derived closed-form approximation (CFA)'s accuracy when comparing with the nearly exact EE in the realistic power consumption models. Using this CFA, we get a low complexity and high efficiency approximate method to address the maximum energy-efficient power allocation policy by accurately approximating the transmit power in closed-form when considering that the aggregate number of transmitted antennas and received antennas are equal in the uplink.
