摘要： A receiver comprises a number of fingers, each finger providing symbols associated with a path of a received multipath signal, and a maximal ratio combiner (MRC) that activates to combine the symbols when the symbols are available. In an illustrative embodiment a receiver is a CDMA receiver and comprises a number of fingers, an interface, and an MRC. Each finger provides symbols asociated with a path of a received multipath signal for the various channels conveyed therein, the interface provides an indiction when symbols from the fingers are ready for processing to the MRC, which then activates to combine those symbols from the fingers that are asociated with the same channel. Illustratively, the interface includes a priority encoder for selecting different channels for processing by the MRC. Further, the MRC can be configured to operate with a clock rate that is greater than a chip rate. By selectively activating the MRC, or at least a portion thereof, a reduction in the number of combining circuits can be achieved within the MRC.

摘要： The disclosed embodiments relate to a method and apparatus for performing a pilot synchronization operation in a wireless communication system. The system may contain a plurality of sliding correlators (102, 106, 110, 114) that each receives a portion of a received correlation sequence and provides a partial correlation output. An absolute value block (118-124) may take the absolute value of each partial correlation output. Circuitry (126) may combine the absolute values of each of the partial correlation outputs to form a correlation output.
