1. A method for gain compensation comprising:

  • (A) detecting a strength of an output signal generated by a power amplifier of a transmitter in response to a commanded transmission signal;

    (B) comparing the detected strength of the output signal to a detected strength of the commanded transmission signal to obtain an error signal;

    (C) compensating for gain drop of the output signal by adjusting a gain of the transmitter based on the error signal,wherein (A), (B) and (C) are performed during a transmission of a single packet.
