Abstract

"MéTODOS E APARELHOS PARA TRANSMITIR SìMBOLOS COMPLEXOS E PARA RECEBER UM SINAL, SISTEMA COMPREENDENDO UM TRANSMISSOR E UM RECEPTOR E MATRIZ DE CóDIGO DE TRANSMISSãO". O desempenho e a taxa de símbolos em um sistema móvel sem fio são incrementados peã formação de uma matriz de código de transmissão usando códigos ortogonais transformados, de uma tal maneira que o código é robusto às estatísticas de canal e funciona bem em ambos os canais Ricean e Rayleigh (correlatos). Ademais, a invenção habilita transmissão de alta taxa de símbolos usando múltiplas antenas de transmissão e uma ou múltiplas antenas de recepção, e obtém simultaneamente alta ordem de diversidade e altas taxa de símbolos ou dados.
