How to achieve Cramer-Rao Bound for the varaince of unbaised estimates?

Muhammad Amjad Iqbal @Muhammad-Amjad-Iqbal

14 June 2021 0 5K Report

I have implemented doppler centroid estimation, now The Cramer-Rao Bound (CRB) method must yield an ultimate accuracy for correlation-based doppler centroid estimation.

I need guidance in this context.
