Abstract

La emisión sincronizada transmite un mismo contenido de emisión utilizando una misma forma de onda desde múltiples transmisores. Los transmisores aplican cada uno un mismo código de dispersión para las transmisiones de la emisión. En un sistema de comunicación espectro-disperso que tiene un enlace delantero de división del tiempo multiplexado, una transmisión sincronizada de emisión se inserta en un espacio de emisión. Una materialización emplea una forma de onda multiplex de divisional ortogonal de la frecuencia (OFDM) para la emisión sincronizada. Un receptor OFDM entonces se utiliza para procesar la transmisión sincronizada de emisión recibida. Una materialización alternativa implementa un código de ruido seudo-aleatorio (PN) en la emisión para su uso por los transmisores múltiples. Un ecualizador entonces se emplea para estimar la transmisión sincronizada de la emisión.
