Robust Microphone Array Algorithm for Reverberant Environments

In this paper, a microphone array algorithm that overcomes the problem of signal cancellation in reverberant environments is proposed. The structure presented in this paper adopts a spatial smoothing algorithm, which was originally proposed for narrowband cases, to solve the problem of a desired signal cancellation phenomenon. In order to evaluate the performance of the proposed algorithm, we build a data acquisition room that models a real living room. With real measured data from the experiment room, the proposed algorithm outperformed conventional microphone array methods.
