TL;DR: This article concentrates on the terrestrial transmission system DVB-T as one example of the many transmission technologies DVB has developed over the last few years and explains some of the fundamental concepts behind the work of this group.
Abstract: A new kind of "wireless video" is currently entering consumers' homes-digital television. The term digital video broadcasting (DVB) is used as a synonym for digital television in many countries of the world. Whereas one may tend to think that digital television means just a new, digital, form of signal representation not necessarily affecting the information content of what one has always called TV, the truth is that digital television becomes multiple-channel data broadcasting. This article reviews some of the results of the work in the worldwide DVB Project and explains some of the fundamental concepts behind the work of this group. It then concentrates on the terrestrial transmission system (DVB-T) as one example of the many transmission technologies DVB has developed over the last few years. The COFDM modulation scheme which is a key ingredient of DVB-T is described in some detail. The performance of the system is presented. The use of DVB for data broadcasting and the accompanying return channel technologies are explained.
TL;DR: Different antenna diversity concepts, which can be easily applied to orthogonal frequency division multiplexing (OFDM) systems, are investigated and applied to the DVB-T system for error performance investigations.
Abstract: In this paper, we investigate different antenna diversity concepts, which can be easily applied to orthogonal frequency division multiplexing (OFDM) systems. The focus is to provide diversity schemes, which can be implemented to already existing OFDM systems without changing the standards. It is also possible to combine these techniques in a suitable manner. The introduced diversity techniques are applied to the DVB-T system for error performance investigations, which were done by simulation.
TL;DR: DVB-T capabilities are described with a special emphasis on mobile reception and the introduction of DVB-T in Germany is looked at using the launch of the system in this country as a case study.
Abstract: Digital video broadcasting-terrestrial (DVB-T) is the name of the terrestrial transmission system which was developed by the DVB Project. DVB-T is in operation in many countries around the world. This paper analyzes the features of the system. It describes its capabilities with a special emphasis on mobile reception and looks at the introduction of DVB-T in Germany using the launch of DVB-T in this country as a case study. In order to analyze how an MPEG transport stream at the input of a DVB-T modulator is turned into a DVB-T signal, we consider the channel coding and modulation used. Then we look at various aspects of the system performance. The next section deals with mobile reception. Network planning issues, antenna diversity concepts for mobile receivers, and handover procedures will be considered. Finally, the introduction of DVB-T in Germany is presented as a case study. In contrast to various other countries Germany decided to offer DVB-T as a means of providing the "anywhere TV" experience. This implies that DVB-T signals can be received with mobile and portable receivers. In regions with DVB-T coverage analogue terrestrial TV services were discontinued just a few months after the launch of DVB-T.
TL;DR: This paper compares the performances of the ATSC 8-VSB, the DVB-T COFDM, and the ISDB-T BST-OFDM digital television terrestrial transmission systems under different impairments and operating conditions.
Abstract: This paper compares the performances of the ATSC 8-VSB, the DVB-T COFDM, and the ISDB-T BST-OFDM digital television terrestrial transmission systems under different impairments and operating conditions First, a general system level description is presented It is followed by comparisons based on laboratory test results and theoretical analyzes The differences in the system threshold definitions are discussed In addition, a performance and implementation analysis is also presented for the three transmission systems under different network infrastructures, whenever possible, the impact on the broadcasters or consumers is discussed Possible performance improvements are also identified
TL;DR: This paper presents a comprehensive concept for target tracking in DAB/DVB-T networks accounting for the characteristics of this signal and derived algorithms will be tested with respect to numerical simulations.
