Abstract

"MéTODOS DE OPERAR UM SISTEMA DE COMUNICAçãO DE RáDIO-TELEFONE DE SATéLITE E DE OPERAR UM PRIMEIRO SISTEMA DE COMUNICAçãO DE RáDIO-TELEFONE DE SATéLITE PARA REDUZIR INTERFERêNCIA DE UM SEGUNDO SISTEMA DE COMUNICAçãO POR SATéLITE, SISTEMA, E, APARELHO". Um primeiro sinal de rádio é recebido por um primeiro caminho de recepção de satélite, por exemplo, uma antena ou feixe pontual, que serve uma célula de satélite. O primeiro sinal de rádio recebido inclui um sinal de ligação superior de satélite desejado transmitido de uma primeira fonte usando uma freqüência designada à célula de satélite e um sinal interferente transmitido de uma segunda fonte usando a freqüência designada à célula de satélite. Um segundo sinal de rádio é recebido por um segundo caminho de recepção de satélite, por exemplo, por outra antena ou feixe pontual do sistema e/ou por um feixe de antena de satélite de outro de sistema. O segundo sinal de rádio inclui o sinal interferente. O primeiro e segundo sinais de rádio são processados para recuperar o sinal de ligação superior de satélite desejado.
