Abstract: 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.
