1. A method for determining reliability of a sensor, comprising:

  • receiving signal samples associated with a sensor;

    receiving an expected standard deviation value associated with the sensor;

    estimating noise standard deviation of the signal samples based at least upon a difference between the received sensor samples and predicted sensor signal values; and

    outputting a noise confidence value based at least in part on a first ratio between the estimated noise standard deviation and the expected standard deviation value.
