Covariance Matrix Reconstruction via a Subspace Method and Spatial Spectral Estimation for Robust Adaptive Beamforming

Algorithm 1

Steps of the proposed algorithm.

Step 1. Calculate the SCM applying (10), and estimate the spatial spectrum by (18).

Step 2. Construct using (15), and calculate via (16) and (17).

Step 3. Estimate the powers of interferences employing (22), and reconstruct through (27).

Step 4. Estimate vector using (29), and obtain the modified SV via (30).

Step 5. Calculate the complex vector of the proposed algorithm through (31).
