The method, which operates in a code division multiple access wireless communication system including a base site having a first and second antenna for receiving communication signals from a mobile unit and a base site receiver for demodulating the communications, includes receiving at a first antenna a first set of signals of the communication signals; processing, by a searcher, the first set of signals to produce an output indicative of a winning correlation energy and an associated pn-offset for at least one of the first set of signals; receiving at a second antenna a second set of signals of the communication signals; and using the output to coordinate demodulation of the at least one of the first set of signals of the communication signals, as a function of its pn-offset, while simultaneously processing, by the searcher, the second set of signals.

[ What we claim is:] [1.] A method for performing a signal search in a code division multiple access wireless communication system, the method comprising the steps of:receiving a communication signal at a first antenna to produce a first received signal;inputting, at a first time offset, at least a first portion of the first received signal to a demodulator having a plurality of outputs to produce a first set of outputs;selecting an output from the first set of outputs to produce a first selected output;inputting, at a second time offset, at least a second portion of the first received signal to a demodulator to produce a second set of outputs;selecting an output from the second set of outputs to produce a second selected output;after selecting the first selected output and the second selected output, re-assigning a RAKE receiver finger for receiving the communication signal at the first antenna;after re-assigning the RAKE receiver finger, receiving the communication signal at a second antenna to produce a second received signal;inputting, at a first time offset, at least a first portion of the second received signal to the demodulator to produce a third set of outputs;selecting an output from the third set of outputs to produce a third selected output;inputting, at the second time offset, at least a second portion of the second received signal to the demodulator to produce a fourth set of outputs;selecting an output from the fourth set of outputs to produce a forth selected output; andafter selecting the third selected output and the fourth selected output, re-assigning the RAKE receiver finger for receiving the communication signal at the second antenna.
