Abstract

<B>CODIFICAçãO DE BLOCO-ESPAçO E CODIFICAçãO DE CANAL COMBINADO EM UM ARRANJO DE MULTI-ANTENAS<D> Um aperfeiçoamento do desempenho é obtido pela combinação de codificação de canal com os princípios de codificação tempo-espaço. Com unidades terminais sincronizadas K transmitindo em antenas N para uma estação-base tendo M K antenas de recepção, são obtidos aumento da capacidade do sistema e melhoria do desempenho pelo uso de um esquema de codificação concatenado onde o código interno é um código de bloco tempo-espaço e o código externo é um código de correção de erro de canal convencional. Os símbolos de informação são primeiro codificados utilizando um código de canal convencional, e os sinais resultantes são codificados utilizando um código de bloco tempo-espaço. No receptor, o código de bloco tempo-espaço interno é utilizado para suprimir a interferência de outros terminais co-canais e decisões temporárias são tomadas em relação aos símbolos transmitidos. A decodificação do canal que se segue toma as decisões permanentes em relação aos símbolos transmitidos. O aumento da velocidade de dados é obtido, efetivamente dividindo-se a velocidade de dados que entram em múltiplos canais, e cada canal é transmitido através de seu próprio terminal.
