Abstract
"CODIFICAçãO DE BLOCOS EM ESPAçO-TEMPO DIFERENCIAL". Um codificador de blocos de espaço-tempo diferencial produz blocos sucessivos espaço-tempo de símbolos de M-PSK símbolos para serem codificados, de acordo com uma matriz ortogonal e um fator de normalização. Blocos de saída de espaço-tempo codificados diferencialmente, para transmissão através de uma pluralidade de antenas de transmissão (16, 18) de um sistema de comunicação sem fio, são produzidos pela multiplicação (42) de cada bloco de espaço-tempo do codificador de blocos de espaço-tempo (40) pelo respectivo bloco de saída de espaço-tempo codificado diferencialmente anterior (44). A decodificação é independente da estimação do canal, e a disposição é simples, evita a propagação de erros, e é aplicada a números diferentes de antenas de transmissão.
