Detection and Estimation Theory Lecture 5 Mojtaba Soltanalian- UIC msol@uic.edu http://msol.people.uic.edu Based on ECE 531 Slides- 2011 (Prof. Natasha Devroye)
The Cramer-Rao Lower Bound ---Last Lecture • the CRLB give a lower bound on the variance of ANY UNBIASED estimator • does NOT guarantee bound can be obtained • IF find an estimator whose variance = CRLB then it’s MVUE
