Abstract

Los datos son transferidos en un sistema de comunicación inalámbrica, como ser un sistema de comunicación inalámbrica espectro disperso. Los datos son codificados para producir una pluralidad de corriente de datos. Para cada pluralidad de antenas de transmisión, las corrientes de datos son utilizadas para producir un vector para su transmisión. Cada vector de transmisión transmitido por su antena de transmisión a través de una interfase aérea inalámbrica que experimenta una trayectoria múltiple.Los componentes de trayectoria múltiple de cada vector de transmisión transmitido, son recibidos por una pluralidad de antenas de recepción. Los componentes de trayectoria múltiple recibidos son ecualizados para recuperar los vectores de transmisión. Los datos son recuperados de los vectores de transmisión recuperados.
