Abstract

<B>MéTODO E APARELHO PARA RESOLUçãO DE COLISãO EM UM SISTEMA DE RADIO-TELECOMUNICAçãO DE RETARDO-CRìTICO<D> Em um canal PRACH, sinais em colisão são resolvidos pelo uso de um número de símbolos semelhantes em treinamento nas carga úteis de dados em colisão. Os sinais são avaliados por filtros espaço-temporais operando em um algoritmo semi-oculto ou baseado em treinamento, e um critério de seleção é aplicado aos sinais estimados, tal como distância do alfabeto finito ou erro médio quadrático.
