Abstract
Un aparato de estación base incluye: una pluralidad de antenas; primer medio de procesamiento de pre-codificación para multiplicar un canal piloto común por una primera ponderación; el segundo medio de procesamiento de pre-codificación para multiplicar el canal piloto común por una segunda ponderación que es ortogonal a la primera ponderación; y el medio de síntesis que sintetiza el canal piloto común multiplicado por la primera ponderación, y el canal piloto común multiplicado por la segunda ponderación. El canal piloto común sintetizado es transmitido desde la pluralidad de antenas.
