In the recent past several approaches about energy efficient user equipments (UE) using intelligent analog and digital frontends (AFE/DFE) have been discussed. Those, which will be referred to in this paper, face the fact, that although efficient energy budget management is an important issue in mobile communication systems, typically quite an amount of energy is wasted in todays UEs. The reason for this is, that both AFEs and DFEs in communication systems are engineered for extracting the wanted signal from a spectral environment defined in the corresponding communication standards with their extremely tough requirements. In a real receiving process those requirements can typically be considered as dramatically less critical. Capturing the environmental transmission conditions and adapting the receiver architecture to the actual needs allows to save energy during the receiving process. In order to face this problem and provide solutions to the given issue, a flexible simulation environment (SE) has been implemented using Matlab. This SE focuses on the Long Term Evolution test case, but is not limited to it. In this paper the structure and configuration abilities of the implemented SE will be described. References to simulation results achieved by using the system will be provided to demonstrate the possibilities of the given architecture.
