Abstract

In this chapter, different references for the G-MWF are presented. In [6], the magnitude of the response \( \tilde{H}_{d} \) was designed to improve the broadband output SNR, whereas the phase term of \( \tilde{H}_{d} \) was set equal to the phase of the ATF in the reference microphone. In [7], an MWF formulation with partial equalization (P-MWF) was introduced, where the overall transfer function was chosen as the envelope of the individual ATFs with the phase of an arbitrary reference microphone. This results in a partial equalization of the acoustic system and an improved broadband output SNR.
