Abstract

Un aparato de transmisión incluye M procesadores de señales que generan respectivamente señales moduladas dirigidas a M aparatos de recepción, M es un número entero igual a o mayor que 2, y una sección de antenas. Cada procesador de señales modula una primera secuencia de bits constituida de dos bits para generar una primera señal modulada y una segunda señal modulada y modula una segunda secuencia de bits constituida de otros dos bits para generar una tercera señal modulada y una cuarta señal modulada, en caso de transmitir múltiples corrientes a un aparato correspondiente de los M aparatos de recepción. La sección de antenas incluye una primera antena que transmite la primera señal modulada y la tercera señal modulada y una segunda antena que transmite la segunda señal modulada y la cuarta señal modulada. Por lo menos cualquiera de las señales transmitidas desde la primera antena o las señales transmitidas desde la segunda antena son señales de fase cambiada.
