Abstract
A communication system applies impedance matching to an antenna specific to individual samples of a transmit signal. The system samples a signal and identifies the peak frequency content of each sample. Based on the peak frequency content, the system identifies an impedance match for a given antenna that provides the greatest energy transmission. The sampled portion of the signal is delayed to accommodate processing time to determine the impedance match and control settings. Control settings may be applied via discrete digital circuitry or continuous analog circuitry.
