Abstract: A generator (304) generates first and second training signals (320, 318) that originate within a wireless communication device (FIG. 3) instead of being received from a source outside the device. A receive portion (212, 214, 216) of the device processes the first training signal to derive a processed training signal. An adaptive equalizer (310) equalizes the processed training signal to derive an equalized training signal. A processor (312) compares the equalized training signal and the second training signal using an adaptive algorithm to derive coefficients for the adaptive equalizer to compensate for variations in the receive portion, and adjusts the adaptive equalizer in accordance with the coefficients to derive a compensated output signal.
