Abstract:
1. A receiver for receiving a signal having epochs of a repeating signal code, comprising: a first channel having a first carrier frequency leveler for providing first frequency leveled signal samples, a signal memory for accumulating said first frequency leveled samples over two or more said epochs according to positions within said epochs for providing supersamples for a signal acquisition mode, and first code correlators for correlating said supersamples with first locally generated code samples for providing acquisition correlation data; at least one second channel having a second carrier frequency leveler for providing second frequency leveled signal samples and second code correlators for correlating said second frequency leveled samples with second locally generated code samples for a signal tracking mode for providing tracking correlation data; and an acquisition/tracking (A/T) switch for switching said second code correlators from the second channel to the first channel for said acquisition mode for augmenting said first code correlators for correlating said supersamples and providing further acquisition correlation data.
