- W862408504 abstract "Microphone array can be used in sound source localization and separation. But gain, phase, and position errors can seriously influence the performance of localization algorithms such as multiple signal classification (MUSIC) algorithm. In this paper, a new calibration method for microphone array with gain, phase, and position errors is proposed. Unlike traditional calibration methods for antenna array, the proposed method can be used in the broadband and near-field signal model such as microphone array with arbitrary sensor geometries in one plane. Computer simulations are presented and simulation results show the new method having good performance. (10) . In this paper, an active-calibration method for microphone array with gain, phase, and position errors is proposed. Microphone array receives only one speech signal in different positions that is known exactly. The frequency with maximum amplitude is chosen to calibrate and locate. Gain, phase errors, and element positions can be estimated. The gain and phase errors in other frequencies can be worked out by repeating the same procedure. After calibration, the performance of MUSIC algorithm used in microphone array is highly improved." @default.
