Abstract | In this paper, a new model of broadband microphone array system is proposed, where wireless transmission is employed to relay the signals to a fast server nearby in order to find the optimal filter coefficients continuously before the filter weights are sent back to the device. By using sequences of calibration signals, we formulate a total least squares problem and transform it into an equivalent optimization problem. By exploiting the structure of the problem, analytic expressions for the optimal solution can be obtained. For illustration, two numerical results are presented. © 2012 ICIC International. |
