Abstract

Un metodo que incluye determinar ponderaciones correspondientes a cada una de la pluralidad de antenas utilizadas para transmitir senales de datos, cada ponderacion es adecuada para modificar una de las senales de datos, correspondiente antes de la transmision utilizando una de las antenas, correspondiente; y transmitir informacion correspondiente al menos a una de las ponderaciones, la informacion permite que se determine al menos una ponderacion. Otro metodo incluye recibir informacion que corresponde al menos a una de una pluralidad de ponderaciones, la pluralidad de ponderaciones corresponde a una pluralidad de primeras antenas utilizadas para transmitir primeras senales de datos, en donde cada ponderacion se utilizo para modificar una de las primeras senales de datos, correspondiente, antes de la transmision utilizando una de las primeras antenas, correspondiente; utilizar la informacion recibida, determinar la pluralidad de ponderaciones correspondientes a la pluralidad de primeras antenas; y utilizar al menos la pluralidad de ponderaciones; y decodificar segundas senales de datos recibidas utilizando una pluralidad de segundas antenas para crear al menos una senal de salida.
