## Normalized CRLB – an alternate form of CRLB and its relation to estimator sensitivity

The variance of an estimate is always greater than or equal to Cramer Rao Lower Bound of the estimate. The CRLB is in turn given by inverse of Fisher...

## Cramer Rao Lower Bound for Phase Estimation

Consider the DSB carrier frequency estimation problem given in the introductory chapter to estimation theory. A message is sent across a channel modulated by a sinusoidal carrier with carrier...

## Efficient Estimators and CRLB

It has been reiterated that not all estimators are efficient. Even not all the MVUE are efficient. Then how do we quantify whether the estimator designed by us is...
