Abstract
A data synchronization method is proposed to synchronize the data in microphone array non-synchronous measurements by employing the Wiener predictor derived from the minimum mean square error criterion. The Wiener predictor synchronizes the asynchronous measurement signal by harnessing the spatio-temporal correlation between the reference microphones and the array. To validate the proposed data synchronization method, extensive simulations and experiments are conducted to compare the results of non-synchronous and synchronous measurements. Both the simulation results and the experimental results confirm that the proposed method using the Wiener predictor for non-synchronous measurements is robust and reliable. Meanwhile, the results show the non-synchronous measurement method has the advantage of improving array aperture and element density.
