Second-Order Statistics Blind Source Separation

Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 3)

The adaptive LCMV beamforming methods discussed in Chap. 4 are based on the constrained minimization of the output power as an optimization criterion. In practice, their performance is subjected to two contradictory constraints. On the one hand, the microphones should be placed as close as possible to the desired source for a good acoustic capture. On the other hand, any leakage of the desired signal in the interferer reference results in a cancelation of the desired signal at the beamformer output and in a poor SIR improvement.
