1. A method for compensating for variations in a receive portion of a wireless communication device including at least one of a receiver and a transceiver, the method comprising in the device the steps of:

  • generating first and second training signals that originate within the device instead of being received from a source outside the device;

    processing said first training signal through said receive portion to derive a processed training signal;

    equalizing said processed training signal in an adaptive equalizer to derive an equalized training signal;

    comparing said equalized training signal and said second training signal using an adaptive algorithm for deriving coefficients for said adaptive equalizer to compensate for the variations in said receive portion; and

    adjusting said adaptive equalizer in accordance with said coefficients to derive a compensated output signal.
