摘要：
In this paper, a robust adaptive microphone array system which has a cone-shaped directionality pattern is presented. The array consists of two linear microphone arrays, arranged in a cross fashion, and incorporates the CCAF-NCAF robust beamformer scheme of Hoshuyama, et al. As indicated in the simulation results, the proposed cross microphone array overcomes problem of spatial ambiguity (unlike a conventional linear array), and has the added advantage of 3-Dimensional interference cancellation. In addition, the system also benefits from the accelerated convergence speed due to a reduced allowable capture region.
