Abstract
Approaches to signal processing using tapered coherent integration time period durations. In this regard, signal processing of received signals (e.g., received satellite navigation signals) may be received at a receiver. The received signals may be processed in a coherent integration process whereby the duration of subsequent coherent integration time periods are reduced in response to errors resulting from frequency instability that grows in time. As such, relatively long durations for coherent integration times may result in improved signal to noise ratios (SNRs) for integrated signals in initial coherent integration time periods. However, as errors that are introduced into the signal processing due grow over time, the durations of subsequent coherent integration time periods may be reduced, thus reducing the effect of the error in a SNR of resulting integrated signals. In turn, receiver sensitivity may be improved.
