Abstract

Son transferidos datos en un sistema de comunicacion inalambrico tal como un sistema de comunicacion inalambrico de espectro difundido. Los datos son codificados para producir una pluralidad de corrientes de datos (figura 2). Para cada una de una pluralidad de antenas transmisoras 34, las corrientes de datos son utilizadas para producir un vector para la transmision. Cada vector de transmision a traves de una interconexion de aire inalambrica que experimenta trayectorias multiple a partir de cada vector de transmision transmitido, son recibidos por una pluralidad de antenas receptoras 36. Los componentes de trayectorias multiples recibidos son igualados para recuperar los vectores de transmision. Los datos son recuperados a partir de los vectores de transmision recuperados.
