PROBLEM TO BE SOLVED: To provide a system and a method for performing the digital receive processing for multiple signals received over the same RF band. SOLUTION: Digital RF samples are stored in a RAM queue which is accessed by a searcher and a demodulator. The searcher and the demodulator are preferably located on the same integrated circuit along with the RAM queue. The demodulator demodulates a set of reverse link signals stored within the RAM queue where each reverse link signal is received with a particular time offset and processed using a particular channel code. The searcher periodically searches for reverse link signals not being processed by the demodulator, and for access requests transmitted via the access channel. The searcher preferably searches during the worthy power control groups of each reverse link signal, which corresponds to the two of sixteen power control groups transmitted during a 1/8 rate frame.
