Single Carrier OFDM for the Next Generation Mobile TV Standard DVB-NGH

Abstract

[ES] En esta Tesis se ha estudiado la modulación de portadora única SC-OFDM para el estándar de nueva generación DVB-NGH. Se ha hecho un estudio de las mejoras aportadas por esta modulación con respecto a técnicas previas.

[EN] The deployment of a TV network is always a challenging task. Legislators usually request operators to guarantee a fair access to the service to a given percentage of the population. These requirements may be costly to satisfy with a terrestrial network, especially in wide areas with low population density. The use of a satellite may also result expensive for a low number of users, and not robust enough to guarantee a good reception for all users. The combination of both components appears as a solution to cover large but sparsely populated areas. The Digital Video Broadcasting-Next Generation Handheld (DVB-NGH) system, currently under standardization, has adopted an optional satellite component. Due to long propagation distances and power limitations, satellite links require modulations robust to saturation for operating power amplifiers with small input back-offs.
