IPC: H04B7/08
Filed: 2002-03-22
Abstract: <P>PROBLEM TO BE SOLVED: To change the directional characteristics of an array antenna without referring to learning sequence signals.  <P>SOLUTION: In a method of controlling the array antenna, three steps are repeated. In the first step, signals received by means of the antenna elements 1-1 to 1-N of the array antenna 100 are multiplied by prescribed weighting factors and an output signal z obtained by summing the multiplied results is outputted. In the second step, in a cumulant of degree 2m having m (m: an integer of ≥2) first variables, (m-1) second variables, and one third variable, a cumulant vector d which includes m identical output signal z as the first variables, (m-1) identical signal z* (complex conjugate of the output signal z) as the second variables, and the complex conjugate vector x* of a received signal vector having each received signal as the third variable, is calculated. In the third step, a weighting factor vector c containing weighting factors as components is calculated based on the autocorrelation matrices R of the received signal vectors x and the cumulant vector d.  <P>COPYRIGHT: (C)2004,JPO
