Application of CG-Lanczos algorithm to robust adaptive beamforming

One of the methods to overcome the problems associated to calibration and pointing errors of SRB's is the projection on signal subspace. Computational cost associated to projection methods is an important drawback. Application of conjugate-gradient-Lanczos method reduces the computational complexity of the overall technique and achieves an algorithm to obtain the set of weights and project onto the signal subspace in one step.
