1.	GPS receivers include a signal that is ____ filtered when it reaches a radio from a satellite.(a) Gaussian(b) Blackman(c) Kalman(d) SobelI have been asked this question in class test.The query is from Available Technologies for Cognitive Radio topic in portion Cognitive Radio Basics of Cognitive Radio
Answer» Correct OPTION is (c) Kalman The best explanation: Kalman filter uses observed values and provides ACCURATE estimates of unknown variables using joint probability distribution over the variables for each TIME frame. GPS receivers INCLUDE a one pulse per SECOND signal that is Kalman filtered.
