14. A method for combining multipath components in a rake receiver for code division multiple access (CDMA) communication, the method comprising:
receiving a signal comprising a plurality of symbols;
demodulating the received signal with a plurality of finger correlators in a location corresponding each of a plurality of strong multipath components of the received signal to generate a finger correlator output;
demodulating the received signal with a plurality of escort correlators in a location within a predetermined distance from the location of a corresponding finger correlator to generate an escort correlator output;
applying a weight vector to outputs from the finger correlators and the escort correlators; and
combining the weighted outputs for symbol detection.
