Abstract

Aspectos de la descripción objeto puede incluir, por ejemplo, recibir, por un elemento de red de un sistema de antenas distribuidas, una señal de referencia y una primera señal modulada a una primera frecuencia portadora, incluyendo la primera señal modulada primeros datos de comunicación proporcionados por una estación base y dirigidos a un dispositivo de comunicación móvil. El elemento convierte la primera señal modulada a la primera frecuencia portadora hacia la primera señal modulada en un primer segmento espectral basándose en un procesamiento de señal analógica de la primera señal modulada y utilizar la señal de referencia para reducir la distorsión durante la conversión. El elemento de red transmite de modo inalámbrico la primera señal modulada en el primer segmento espectral hacia el dispositivo de comunicación.
