A signal enhancement method using the iterative blind deconvolution for microphone array system

This paper proposes an adaptive microphone array using blind deconvolution. The method realizes an signal enhancement based on the combination of blin d deconvolution, synchronized summation and DSA (Delay-and-Sum Array) metho d. The proposed method improves performance of estimation by the iterative operation of blind deconvolution using a cost-function based on the coheren cy function.
