Physical Layer Signaling for the Next Generation Mobile TV Standard DVB-NGH

Abstract

[ES] Esta tesina tiene como objetivo investigar, estudiar y desarrollar la nueva capa física para la nueva generación TV digital móvil DVB-NGH. Esta nueva capa física se basa en las especificaciones de la capa física de DVB-T2, pero introduce una serie de mecanismos avanzados que permiten la transmisión de servicios HDTV en entornos móviles.

[EN] The next generation mobile broadcasting standard DVB-NGH (Next Generation Handheld) has enhanced the physical layer signaling of DVB-T2 (Second Generation Terrestrial) in several aspects: higher signaling capacity, improved transmission robustness, reduced signaling overhead, and reduced peak-to-average-power ratio (PAPR). The physical layer signaling of DVB-T2 and DVB-NGH is transmitted in preamble OFDM symbols at the beginning of each frame. The preamble provides a means for fast signal detection, enabling fast signal scanning, and it carries a limited amount of signaling data in a robust way that allows accessing the physical layer pipes within the frame. This thesis provides an overview of the physical layer signaling in DVB-NGH. Results are compared with DVB-T2.
