<p>[PROBLEMS TO BE SOLVED] An adaptive array control method, device, and program, and an adaptive array processing method, device, and program are provided to precisely carry out coefficient updating control independent of frequency characteristics of a signal or its arriving direction. [MEANS FOR SOLVING THE PROBLEMS] A solution for the problems is characterized in carrying out array-processing of signals received from a plurality of differently spaced sensor pairs, and precisely estimating a disturbing power by using an obtained result of the array-processing. More concretely, a multiple blocking matrix circuit (320) is provided to carry out the array-processing of the signals received from a plurality of differently spaced sensors and, based on its output of an array-processed signal, precise coefficient updating control is executed, so that deterioration of an output signal or breathing noise is reduced and high quality array processing can be performed.</p> |
