摘要:
A system and method for performing the digital receive processing for multiple signals received over the same RF band is described. In a preferred embodiment of the invention, digital RF samples are stored in a queue which is accessed by a searcher (130) and demodulator (112). The searcher (130) and demodulator (112) are preferably located on the same integrated circuit along with the queue. The demodulator (112) demodulates a set of reverse link signals stored within the queue where each reverse link signal is received with at a particular time offset and processed using a particular channel code. The searcher (130) periodically searches for reverse link signals not being processed by the demodulator (112), and for access requests transmitted via the access channel. The searcher (130) 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 an eighth rate frame.
