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 may relate to a method and apparatus for performing a correlation with respect to a received signal. A first correlator (108) may correlate for a real part of a first characteristic of the received signal to produce a first real correlated signal. A second correlator (110) may correlate for an imaginary part of the first characteristic of the received signal to produce a first imaginary correlated signal. A third correlator (114) may correlate for a real part of a second characteristic of the received signal to produce a second real correlated signal. A fourth correlator (116) may correlate for an imaginary part of the second characteristic of the received signal to produce a second imaginary correlated signal. Logic (118) may combine a signal that corresponds to the first real correlated signal, a signal that corresponds to the first imaginary correlated signal, the second real correlated signal and the second imaginary correlated signal to produce a real part of a frequency adjusted signal and an imaginary part of the frequency adjusted signal.
