This paper presents a novel array processing algorithm for noise reduction in a hands free car environment. The algorithm incorporates the spatial properties of the sound field in a car cabin and a constraint on allowable speech signal distortion. Our results indicate that the proposed algorithm gives substantial performance improvement of 15-20 dB in comparison with the conventional array processing which is based on a coherent model of the signal field.
