Effective signal processing of modern digital communication standards requires the use of an analog-to-digital conversion with a sampling rate corresponding to the clock frequency of the analyzed communication system. Radio monitoring systems, analyzing signals from a wide range of standards, need to use an extensive set of sampling frequencies and, as a consequence, resamplers that change the sampling frequency of signals already presented in digital form. The method proposed and analyzed in this paper, based on optimizing the parameters of the interpolation polynomials and on optimizing the construction scheme, is aimed at improving the energy efficiency of the FPGA resamplers implementation, i.e. to ensure the possibility of making arbitrary changes in the sampling rate with the minimum power consumed by the resampler.
