Abstract

다중 신호 경로로부터 제공되는 신호들은 멀티 구성요소 안테나(20) 및 빔형성 네트워크(34)를 이용하여 수신 된다. 각 안테나 구성요소의 신호들은 샘플 벡터를 형성하기 위해 샘플된다. 몇개의 샘플 백터는 자동 공분산 매트릭스률 형성하기 위해 이용된다. 자동 공분산 메트릭스의 신호값 분해는 3개 매트릭스를 형성하기 위해 이용된다. 제1매트릭스는 신호 경로의 갯수를 결정하기 위해 이용되고, 제2매트릭스는 몇개의 다항식을 형성하기 위해 이용된다. 단위 범위상 또는 근처에 있는 다항식 근들은 각 신호 경로와 관련된 단위 범위상의 점을 결정하기 위해서 이용된다.
상기 단위 범위상의 각 점은 각 신호 경로에 대하여 수신 빔을 형성하는 빔 형성 네트워크(34)에 대한 가중치를 계산하기 위하여 이용된다.
