Significant knowledge about microphone arrays has been gained from years of intense research and product development. There have been numerous applications suggested for example from large arrays in the order of 100 elements for use in auditoriums to small arrays with only 2 or 3 elements for hearing aids and mobile telephones. Apart from that microphone array technology has been widely applied in speech recognition surveillance and warfare. Traditional techniques that have been used for microphone arrays include fixed spatial filters such as frequency invariant beamformers optimal and adaptive beamformers. These array techniques assume either model knowledge or calibration signal knowledge as well as localization information for their design. Thus they usually combine
