1. A system for processing a data stream obtained from a glucose sensor, the system comprising:

  • a signal processing module configured to monitor a data stream from a continuous glucose sensor over a period of time;

    a detection module configured to determine a severity of signal artifacts in the data stream based on an amplitude and a duration of the signal artifacts;

    a signal estimation module configured to selectively apply one or more coefficients or parameters to a signal estimation algorithm based on the severity of the signal artifacts and to apply the signal estimation algorithm to the data stream to generate an estimated signal.
