Abstract :
For mobile user equipments (UE) a careful power management is essential. Despite this fact, quite an amount of energy is wasted in todays UEs analog and digital frontends. Those 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. Knowledge about the actual environmental spectral conditions allows to reconfigure both frontends to the actual needs and to save energy. In the recent past several approaches solving this issue for Long Term Evolution systems using multiplier free multi rate low cost filter banks have been discussed. In this paper we present a co-simulation environment for an efficient hardware implementation of the proposed algorithms using Matlab and two Field Programmable Gate Array platforms. The specific hardware setup as well as the used communication protocols between hardware and software are discussed.
