Abstract

For mobile communication systems power efficiency is a very important issue. Especially for mobile user equipments a careful management and efficient use of the limited energy ressources is mandatory. In today's user equipments quite an amount of energy is wasted. The reason for this is, that analog and digital frontend in communication systems are engineered for extracting the wanted signal from a spectral environment, which is defined in the corresponding communication standards with strict requirements. In a real receiving process those requirements can typically be considered as less critical. Sensing the environmental transmission conditions and adapting the receiver architecture to the actual needs allows to save energy during the receiving process. An efficient architecture being able to fulfill this task for a typical Long Term Evolution scenario has been disussed recently. For the implementation of this architecture, highly efficient filter approaches had to be investigated. This paper gives an overview on the basic properties of those approaches and compares it to well known filter types.
