چکیده
Digital Video Broadcasting Next Generation Handheld (DVB-NGH) is a hybrid terrestrial-satellite standard conceived to facilitate rich media content consumption using a variety of mobile, handheld devices. Still under drafting, the DVB-NGH specifications are to be released current 2012 with the target of offering superior performance, robustness and coverage with respect to existing solutions. The purpose of this paper is to give an overview of the physical layer of the satellite component of DVB-NGH and to give some insight on the motivation and technical choices that were made during the specification phase, with a focus on the waveform choice and on the pilot grid design. Keywords-DVB-NGH, satellite, SC-FDMA, SC-OFDM, hybrid pilot, PAPR.

Multi Antenna Techniques for Digital Video Broadcasting (DVB) Systems
In this paper we describe the potential of multi-antenna techniques (MIMO) in the context of digital video broadcasting (DVB) systems. DVB standards have been challenged by the increasing demand of high data rate applications and larger indoor coverage area. MIMO is a key technology to increase the system capacity and link reliability without any additional bandwidth or transmit signal power. T...
متن کاملUpper Layer Fec for Dvb-sh: Technical Solutions and Performance
A new system for hybrid satellite and terrestrial broadcasting of multimedia services to mobile handheld receivers has been recently standardised by DVB, namely DVB-SH. Direct mobile reception by S-band satellites is affected by obstacles (trees, buildings, bridges,..) blocking the Line-of-Sight (LoS) propagation, producing deep signal fading events lasting up-to several seconds or even more. T...

Satellite links are expected to be one important component of the next-generation Internet. New satellite system architectures are being envisaged to be fully IP based and support digital video broadcasting and return channel protocols (e.g. DVB-S, DVB-S2 and DVB-RCS). To make the upcoming satellite network systems fully realizable, meeting new services and application requirements, a complete ...
متن کاملCombined Time, Frequency and Space Diversity in Multimedia Mobile Broadcasting Systems
The combined use of diversity in the time, frequency, and space domains constitutes a powerful instrument to improve the reception of mobile broadcasting services. The improvement brought by the utilization of diversity techniques can be translated into an extended coverage of mobile services, or into a reduction of the network infrastructure. This dissertation addresses the use of diversity fo...
