Abstract

"APARELHO DE RECEPçãO DE RáDIO E MéTODO PARA SUA CALIBRAçãO". Um aparelho de recepção de rádio, de acordo com a presente invenção que inclui uma antena de arranjo tendo uma pluralidade de antenas e uma unidade de recepção de antena, e obtém um valor de correção usando um sinal de calibração conhecido. O aparelho de recepção de rádio adicionalmente inclui uma unidade de recepção de diversidade que recebe as saídas de recepção da pluralidade de antenas como entrada, e executa o processamento de diversidade e fornece os resultados, uma unidade de monitoramento de qualidade de recepção de diversidade para monitorar a qualidade de recepção da recepção de diversidade, e uma unidade de monitoramento de qualidade de recepção de arranjo para monitorar a qualidade de recepção da recepção de antena de arranjo. Se a qualidade de recepção da recepção de diversidade for equivalente à qualidade de recepção da recepção de antena de arranjo, então a calibração da unidade de recepção de arranjo será executada enquanto se implementa a recepção de diversidade de modo a obter os valores de correção de flutuação de amplitude e desvio de fase da unidade de recepção de arranjo.
