Abstract

MéTODO DE COMUNICAçãO DE RáDIO, SISTEMA DE COMUNICAçãO DE RáDIO E DISPOSITIVO DE COMUNICAçãO DE RáDIO. A invenção refere-se a um dispositivo de comunicação de rádio e outras capazes de gerar, em um curto período de tempo, um código secreto comum a uma estação de base e a uma estação móvel em um sistema de comunicação sem fio que usa a técnica MIMO, e de dar inicio à comunicação criptografada em um estágio prematuro. Neste dispositivo, na etapa ST545, quando uma unidade de julgamento de coincidência de canal (105) e uma unidade de processamento de julgamento de coincidência de canal (205) julgarem, respectivamente, que a matriz de canal gerada pela estação de base coincide por completo com a matriz de canal gerada pela estação móvel ou que elas não coincidem por completo, mas podem enfim coincidir com a correção de erro do código secreto ou similar, de acordo com o resultado de julgamento indicado no sinal de julgamento de coincidência de canal gerado na etapa ST540-2, a etapa ST545 será seguida pela etapa ST550. Por outro lado, quando a matriz de canal gerada pela estação móvel não coincidir completamente com a matriz de canal gerada pela estação de base e elas enfim não coincidirem, mesmo depois da correção de erro do código secreto, a etapa ST510 será novamente executada depois da etapa ST545.
