1. A method for wireless communication, the method comprising:

  • in a chip comprising integrated FM radio receiver and FM radio transmitter functions;

    utilizing on-chip measurement of one or more signals reflected from an antenna to determine a best impedance match between said antenna and said FM radio receiver and/or said FM radio transmitter; and

    incorporating a correction algorithm into said determination of said best impedance match between said antenna and said chip, wherein said correction algorithm is determined utilizing data from an external test set that measures FM signals transmitted by said chip via said antenna.
