A New Method to Calculate Complex Cramér-Rao Bound for Line Spectrum Estimation with Multiple Measurement Vectors

A new method to calculate the complex Fisher information matrix (FIM) and the Cramér-Rao bound (CRB) is proposed for line spectrum estimation (LSE) with multiple measurement vectors (MMVs), 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.
