摘要： 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.

摘要： A processor (216) time-shares correlators (206) to process (402) pilot channels for a plurality of branches to derive pilot symbols for each of the plurality of branches before processing control and data channels. The processor and the correlators cooperate to determine (404) from the pilot symbols a timing estimate for each of the plurality of branches. A signal quality estimator (210) determines (406) from the pilot symbols a signal quality for each of the plurality of branches. Subsequently, the processor cooperates with the correlators to process (408) the control and data channels of the plurality of branches, in an order determined by a plurality of branch attributes including at least one of the signal quality and the timing estimate determined for each of the plurality of branches.
