Abstract

"SISTEMA DE MúLTIPLAS ENTRADAS E MúLTIPLAS SAìDAS EFICIENTE PARA CANAIS COM FADING POR MúLTIPLOS TRAJETOS". Dados são transferidos em um sistema de comunicação sem fio, tal como um sistema de comunicação de espectro de difusão sem fio. Os dados são codificados para produzir uma série de fluxos de dados (Fig. 2). Para cada uma dentre uma série de antenas de transmissão (34), os fluxos de dados são utilizados para produzir um vetor para transmissão. Cada vetor de transmissão é emitido pela sua antena de transmissão através de interface de ar sem fio que experimenta trajetos múltiplos. Componentes de múltiplos trajetos de cada vetor de transmissão emitido são recebidos por uma série de antenas de recepção (36). Os componentes de múltiplos trajetos recebidos são equalizados para recuperar os vetores de transmissão. Os dados são recuperados dos vetores de transmissão recuperados.
