SYSTEMS, METHODS, AND APPARATUS FOR DETECTING IRREGULAR SENSOR SIGNAL NOISE
First Claim
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.

Abstract
Certain embodiments of the invention may include systems, methods, and apparatus for detecting irregular sensor signal noise. According to an example embodiment of the invention, a method is provided for determining reliability of a sensor. The method may include receiving signal samples associated with a sensor; receiving an expected standard deviation value (508) associated with the sensor; estimating noise standard deviation of the signal samples (504) 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.
