Abstract: A multichannel time shared demodulator (10) is implemented in an efficient ASIC architecture that provides routing-of user voice channels and access channels to a collection of time-shared processors for rapid signal detection, tracking and demodulation. The channels are routed in a random order and then processed by a time-shared symbol synchronization processor (18) for voice channels and a time-shared detection processor for access channels. The signals are over-sampled via a time-shared interpolation filter. The interpolation process yields a ten to one over sampling ration of all signals. A synchronized clock is used to choose the phases of the interpolation filter outputs.
