Abstract
COMUNICAçãO DE DADOS EM UM SISTEMA DE COMUNICAçãO SEM FIO USANDO CODIFICAçãO DE ESPAçO-TEMPO é descrito um método para controlar a comunicação de dados em um sistema de comunicação sem fio compreendendo medir a qualidade do canal dos dados recebidos de uma estação base tendo múltiplas antenas, onde a estação base e uma estação móvel estão em uma comunicação de codificação de espaço-tempo (CET) de malha fechada. O método também compreende determinar uma primeira matriz de peso baseado no número de antenas múltiplas da estação base, a matriz de peso compreendendo elementos de peso. O método também compreende determinar uma segunda matriz de peso a partir da primeira matriz de peso em resposta a uma condição pré-determinada, onde a segunda matriz de peso está associada com o controle da saída de dados usando as múltiplas antenas da estação base, para transmissão subseqüente. O método também compreende prover o número de saldas de CET para a estação base, onde o número de saídas de CET está associado com a segunda matriz de peso.
