Abstract

"SISTEMA SEM FIOS E PROCESSO PARA CáLCULO DE SINAIS DE INTERLIGAçãO DE ENVIO TRANSMITIDOS DE UMA PLURALIDADE DE TERMINAIS REMOTOS". Trata-se de um sistema sem fios compreendendo uma rede de estações de base (1) para recepção de sinais de interligação de envio transmitidos de uma pluralidade de terminais remotos e para transmissão de sinais de interligação de recepção para os terminais remotos utilizando uma pluralidade de canais incluindo uma pluralidade de elementos de antena (19) em cada estação de base para recepção dos sinais de interligação de envio, uma pluralidade de elementos de antena (18) em cada estação de base para transmissão de sinais de interligação de recepção, um processador de sinais (13) em cada estação de base ligado aos elementos de antena de recepção (19) e aos elementos de antena de transmissão (18) para determinação de funções de multiplexação de desmultiplexação espaciais-temporais para cada antena remota para cada canal, e um dispositivo controlador de rede de múltiplas estações de base para otimização de desempenho da rede, em que dessa forma a comunicação entre as estações de base e os terminais remotos pode ocorrer simultaneamente em cada canal.
