PROBLEM TO BE SOLVED: To provide a transmission/reception method which performs load calculation in a digital manner while performing suppression processing of an interference wave in an analog manner, and solves the problem of circuit imbalance that may occur therewith, between a suppression processing system and a load calculation system.SOLUTION: A load of an analog adaptive filter 10 is calculated by acquiring reception signals 108 and 109 by turning off a reception signal side switch 7 and turning on a transmission signal side switch 8, and calculating a channel balance matrix by multiplying correlation vectors of the reception signals 108 and 109 by an inverse matrix of a covariance matrix of the reception signal 109, and by acquiring the reception signals 108 and 109 by turning on the reception signal side switch 7 and turning off the transmission signal side switch 8, and multiplying correlation vectors of a signal resulting from multiplying the reception signal 109 by the channel balance matrix and the reception signal 108 by an inverse matrix of a covariance matrix of the signal resulting from multiplying the reception signal 109 by the channel balance matrix. |
