OFDM DVB T2 transmitter simulation
2011 19thTelecommunications Forum (TELFOR) Proceedings of Papers, 2011Simulation models used for DVB, with minor amendments may be applied to DVB-T2. But for the simulation of all possibilities of DVB-T2 need new modules. The simulation becomes more complex and requires the use of algebraic computer systems with the symbolic signal processing.

Evaluation of SFN gain for DVB-T2
2017 International Conference on Digital Arts, Media and Technology (ICDAMT), 2017The evaluation of power gain and modulation error ratio (MER) gain of Digital Video Broadcasting - Second Generation Terrestrial (DVB-T2) for Single Frequency Network (SFN) is very important for the performance of the receiver. The power gain and MER gain are considered based on the data measurement. However, the quality of service in the SFN area will

Coexistence of DVB-T2 and LTE in the 800 MHz Band: Analysis of DVB-T2 System Configurations
2018 IEEE International Symposium on Broadband Multimedia Systems and Broadcasting (BMSB), 2018During the last World Radiocommunication Conference it was decided that the upper frequency parts of UHF bands (700 MHz and 800 MHz) shall be released for mobile services, provided by Long Term Evolution (LTE) system. This decision has caused coexistence issues between the 2nd generation digital terrestrial video broadcasting (DVB-T2) and the LTE ...

High mobility along with multipath propagation in mobile reception results in a doubly selective channel that exhibits selectivity in both the time and frequency domain. The estimation and subsequent compensation of such a channel is a non-trivial task.

A Fast Metaheuristic for the Design of DVB-T2 Networks
2018In order to better exploit scarce radio spectrum resources, the second generation of the Digital Video Broadcasting - Terrestrial standard (DVB-T2) has been developed and is under adoption in many countries, especially in Europe, for providing digital television services.

Experimental study of DVB-T2 in Thailand
2016 International Computer Science and Engineering Conference (ICSEC), 2016This paper presents an analysis of digital television broadcasting, that used DVB-T2 standard, in Bangkok Thailand. The result of analysis has derived from signal measurement 20 location in Bangkok. The measurement location consists of several difference areas such as an urban area, high building area, open area.

An FFT core for DVB-T2 receivers
2009 16th IEEE International Conference on Electronics, Circuits and Systems - (ICECS 2009), 2009This paper presents the design and implementation of a pipeline radix-25 SDF FFT core for DVB-T2 receivers. DVB-T2 operation needs 1K/2K/4K/8K/16K/32K multiple mode FFT processors. The radix-25 SDF architecture is a new and more efficient architecture, which has been optimized for implementing a multiple mode core.

Analysis of ICI compensation for DVB-T2
2010 7th International Symposium on Wireless Communication Systems, 2010This paper analyzes the impact of inter-carrier interference (ICI) compensation on the physical layer of DVB-T2, the new digital terrestrial television standard. We compare the performance of a well-known low complexity soft demapper for different time-interleaving depths and code rates in several realistic mobile scenarios. This paper further presents

Localization using DVB-T2 Signals
2014 International Conference on Engineering and Technology (ICET), 2014The Global Navigation Satellite System (GNSS) has grown significantly in the last recent years. Unfortunately, in some environments such as dense urban or indoor areas, GNSS suffers from poor precision and lack of satellite visibility. Therefore, another positioning system is required to replace or augment GNSS in those environments. The use of Signals

Although DVB-T2 is a significantly more complex standard than other norms and hence requires more computing power in the DVB-T2 measuring receiver, the parameters measured are essentially the same, namely: RF level Bit Error Ratios (BER) Modulation Error Ratios (MER) Constellation diagram (appearance, shape) Shoulder ...
