Abstract
A signal extraction method is provided. In the method, signals are extracted by using K beam forming parts, wherein K is a natural number equal to or more than 2, and received signals from a plurality of antennas are applied to each beam forming part. The method includes the steps of: the received signals being processed by each beam forming part successively; a first beam forming part extracting a first signal from the received signals; and a kth beam forming part canceling, from the received signals, signal components which are extracted by beam forming parts from the first beam forming part to a (k−1)th beam forming part so as to extract a kth signal, wherein 2≦k≦K.
