Abstract

"MéTODO E EQUIPAMENTO PARA REDUZIR INTERFERêNCIA COM CONTROLE DE POTêNCIA EM MALHA EXTERNA EM UM SISTEMA DE COMUNICAçãO SEM FIO". Método e equipamento para reduzir a interferência em um sistema de comunicação sem fio quando a fonte da interferência é um componente determinístico do sistema. O método compreende as etapas de receber transmissões em uma pluralidade de canais, cada um deles associado a uma taxa de erro de bloco; selecionar um canal para aplicação a um controle de potência em malha externa com base nas taxas de erro; e executar o controle de potência em malha externa com base no canal selecionado, que é o canal de controle dedicado. O método pode ser aplicado em sistemas W-CDMA.
