A New Method to Calculate Complex Cramér-Rao Bound for Two-Dimensional Direction-of-Arrival Estimation with Multiple Measurement Vectors

A new method to calculate the complex Fisher information matrix (FIM) and the Cramer-Rao bound (CRB) is proposed for tw 0-dimensional direction-0f-arrival (2D-DOA) with multiple measurement vectors (MMVsi. The detailed theoretic calculation process is presented in the text Finally, numerical results are conducted not only to verify accuracy of the theoretical result by comparing against another method to calculate complex CRB, but also to demonstrate the effectiveness of CRB as the performance metric
