A method for processing signals includes generating a frequency response adjusted signal of an antenna, and adjusting a gain of the antenna by varying a gain of a programmable amplifier that amplifies the frequency response adjusted signal. The generating of the frequency response adjusted signal may take place prior to the gain adjusting. A frequency response of the antenna may be dynamically adjusted during the generating. A programmable filter used for the generating may be autonomously adjusted. The gain of the antenna may be dynamically adjusted. The gain of the programmable amplifier may be autonomously varied. The programmable filter and the programmable amplifier may be adjusted sequentially.
