Abstract
Equipo de usuario que utiliza un esquema de diversidad en un sistema de telecomunicaciones de acceso maltiple por division de códigos, CDMA, que comprende: medios de recepciÓn (26) para recibir datos que se transmiten espacialmente incluyendo una primers rafaga decomunicación transmitida por un primer medio de transmisión y una segunda rafaga de comunicación transmitida por un segundo medio de transmisión, en el que se proporcionan los mismos datos pare la primera y la segunda Wage de comunicación, dichos datos comprendiendo dos campos de datos, produciendose la primera y la segunda rafaga de comunicación utilizando tin primer y un segundo código de canalizado en dichos, campos de datos, respectivamente, cada código de canalizado estando asociado unicamente con uno de dichos primero y segundo medios de transmision, transmitiendose la primera y la segunda ráfaga de comunicación desde una misma estacion base en un mismo segmento de tiempo y cada una de la primera y la segunda rafaga de comunicación teniendo una secuencia de entrenamiento intermedia insertada, asociada con los medios de transmision, utilizada para estimar una respuesta de canal, y on codigo de aleatorizacion asociado con la estación base transmisora; medios de deteccion (24) pars detectar los simbolos de dicha primera y segunda ráfaga de comunicación mediante el uso del primer y el segundo codigo de canalización; medios de descodificación (22) para descodificar dichos simbolos detectados de la primera y la segunda ráfaga de comunicación para generar un unico campo de datos de simbolos detectados; y medios de estimacion (23) pars estimar la respuesta del canal de la primera ráfaga de comunicación como una primera respuesta de canal utilizando la secuencia de entrenamiento intermedia de la primera rafaga de comunicación y para estimar la respuesta del canal de la segunda ráfaga de comunicación coma una segunda respuesta de canal utilizando la secuencia de entrenamiento intermedia de Is segunda ráfaga de comunicacion, y en el que el primer y el segundo código de canalización son diferentes entre si y el primer codigo de canalización se utilize exclusivamente para la transmision sobre el primer medio de transmision y el segundo código de canalización se utilize exclusivamente para la transmision sobre el segundo medio de transmisión.
