System and method for adaptive multi-sensor arrays

摘要

An adaptive differential microphone array method comprises receiving a signal X, estimating a measured signal spectral covariance matrix of the signal (101), and estimating a direction of arrival of the signal based on the measured signal spectral covariance matrix of the signal (102). The method further comprises determining a fractional delay, and applying a differential microphone array filter to the signal based on the direction of arrival and the fractional delay (103) .
