Abstract

cancelamento cego de interferência de enlace ascendente em rede sem fio. cancelamento de interferência cego é descrito para redes sem fio, nas quais uma estação base ou aparelho de cancelamento obtém informação semi-estática para pelo menos uma de suas células vizinhas. a estação base mede o nível de ruído de cada uma das células vizinhas com base nas amostras que recolhe das transmissões de enlace ascendente em cada uma das células vizinhas. as células vizinhas são então classificadas para cancelamento de interferência com base em seus níveis de ruído relativos. a estação base realiza a detecção de transmissão descontínua (dtx) para identificar pelo menos um equipamento de usuário interferente (ue) na célula vizinha e cancela a interferência atribuída a estes ues iterferentes identificados. a detecção dtx e o cancelamento são então repetidos para as células vizinhas restantes na ordem em que são classificadas.
