Abstract

"PROCESSO PARA REDUZIR UM COMPONENTE DE INTERFERêNCIA DE UM SINAL DE DADOS, RECEPTOR QUE REDUZ UM COMPONENTE DE INTERFERêNCIA DE UM SINAL DE DADOS, RECEPTOR MóVEL QUE REDUZ UM COMPONENTE DE INTERFERêNCIA DE UM SINAL DE DADOS, E, ACESSóRIO PARA O TERMINAL DE USUáRIO MóVEL" Um processo para reduzir interferência combina símbolos temporários usando dispositivos de processamento existentes. Em particular, sinais de dados transmitidos são recebidos sobre uma pluralidade de vias. O sinal de dados recebido inclui um componente de interferência. Os sinais de dados recebidos são processados para prover uma pluralidade de símbolos temporários que corresponda ao sinal de dados transmitido. A pluralidade de símbolos temporários é combinada para reduzir o componente de interferência do sinal de dados e sinal de saída provido que corresponde ao sinal de dados transmitido. Conseq³entemente, equalizadores e combinadores existentes podem ser usados para reduzir a interferência. Terminal de usuário móvel e receptores relacionados são revelados.
