Abstract

MÉTODOS E EQUIPAMENTOS PARA SELEÇçO DE DECODIFICADORES EM SISTEMAS DE COMUNICAÇçO. São descritas técnicas para escolha eficiente de um decodificador na presença de mobilidade e/ou Doppler variável. Em um aspecto, um método para a seleção de um filtro para decodificar informações de link direto (EL) em uma rede de comunicação sem fio compreende os atos de decodificação de informações de link reverso (RL) por uma pluralidade de decodificadores, cada um sendo otimizado com base em um parâmetro diferente, e comparação de uma pluralidade de saídas provenientes dos decodificadores, com base em uma métrica, para a determinação de um decodificador ou parâmetro desejado para reportar para um terminal de acesso.
