An iterative implementation of eigenspace-based beamforming is introduced. An approximate expression of signal subspace projection is first derived, and then the eigenspace-based beamformer is innovatively implemented with a two-stage beamforming scheme. The proposed method is capable of avoiding the source number estimation or subspace projection operation, which are indispensable for existing solutions. Hence, it can be fast and conveniently applied in programming. The effectiveness of the proposed technique is demonstrated by simulations.
