Abstract

Un transmisor utilizado en un sistema de comunicación móvil, que emplea un sistema de portador único en el enlace ascendente, comprende un medio de multiplexión que multiplexa un canal piloto, un canal de control y un canal de datos y un medio de transmisión que envía un símbolo de transmisión que incluye al menos el canal piloto y el canal de control en el enlace ascendente. Un primer canal piloto que mide el estado del canal de enlace ascendente con un receptor es transmitido en una banda de frecuencia a través de una pluralidad de bloques de recurso. Un segundo canal piloto que compensa el canal transmitido en el enlace ascendente es enviado a través de un bloque de recurso distribuido a la estación. Los canales de control de la estación local y otra estación son generados para interceptarse entre sí en ángulos rectos en un sistema FDM.
