The combination of binaural processing with adaptive beamforming for dual microphones in speech communications

This paper proposes a new scheme to achieve both the array processing benefits and binaural listening benefits for many application fields of speech communications. In this proposed scheme, we mainly employ two adaptive spatial processing filters. These two adaptive spatial processing filters have the same reference signal which comes from two microphones but they have the different primary signals which correspond to the right microphone signal and the left microphone signal, respectively. Furthermore, these two adaptive spatial filters have the same structure and use the same adaptive algorithm. With this scheme, we can achieve better and more effective combination of binaural processing with spatial processing than some available schemes.
