Abstract

"SISTEMA RECEPTOR (RRC), E, MéTODO DE RECEPçãO DE RáDIO" A presente invenção refere-se a sistemas de rádio e, mais particularmente, a um método e aparelho para recepção de sinais de rádio com o auxílio de feixes gerados por conjuntos de antenas. Para cada um dos feixes em um primeiro dos conjuntos de antena, existe um feixe no segundo dos conjuntos de antena que cobre a mesma área espacial. Os sinais recebidos pelo segundo são retardados com relação aos sinais recebidos pelo primeiro dos conjuntos de antena. Então, os sinais do primeiro conjunto de antena são combinados com os sinais do segundo dos conjuntos de antena. Os sinais combinados derivam de feixes que cobrem a mesma área espacial. Cada sinal combinado é, então, recebido por rádio em um receptor articulado de rádio. A estimativa-DOA pode ser calculada com base nos sinais de rádio recebidos derivados de todos os feixes.
