Abstract
In this letter, a new design method for broadband microphone arrays is presented. Using sequences of calibration signals, the method is able to design finite-impluse response (FIR) filters with specific performance. The method can control and adjust the speech distortion, noise suppression, and echo cancellation directly. It turns out that significantly shorter filter length can be applied to achieve better overall performance than the least-squares method or the signal-to-noise plus interference method.
