Abstract

"MéTODO, APARELHO E SISTEMA PARA SUPRIMIR A INTERFERêNCIA CO-CANAL NO RECEPTOR". Método de operação de um filtro (12) do receptor (10) da estação móvel ou da estação base da rede de acesso de rádio e um equipamento correspondente, o método para uso na supressão de interferência co-canal e baseado na separação dos componentes em fase (I) e em fase de quadratura (Q) do sinal recebido, executa então o branqueamento com base em símbolo-por-símbolo, isto é, a operação de branqueamento é feita dentro de um símbolo. A invenção provê um filtro (12) incluindo um módulo (12b) para executar o branqueamento IQ (de acordo com a invenção ou por outro lado), e também provê um comutador (12a) que pode ser usado para habilitar ou desabilitar o branqueamento IQ, dependendo do caracter do sinal recebido, e em particular baseado na matriz <sym>~ ii~ de correlação de interferência-ruído.
