Abstract

"MéTODO E APARELHO PARA MEDIçõES DE INTERFERêNCIA CO-CANAL E SEPARAçãO DE COMPONENTE DE INTERFERêNCIA BASEADO EM PROCESSAMENTO DE SINAL ESTATìSTICO EM áREA DE TESTE DE DIREçãO". Um método e aparelho para exclusivamente identificar fontes de sinal em um sinal de múltiplas fontes. Níveis verdadeiros de componentes de sinal transmitidos por cada uma das estações base de co-canal na área sob teste em uma rede sem fio são medidos e associados à estação base apropriada (original) na presença de interferência de canal adjacente e co-canal sem serviço de interrupção. A presente invenção é baseada em uma aproximação e conta com medições de tempo de chegada relativo (RTOA) dos componentes de sinal impenetrável à existência de desvio de fase entre o digitalizador e estações base.
