A MIMO-Channel-Precoding Scheme for Next Generation Terrestrial Broadcast TV Systems

Vargas, D.; Kim, Y.J.D.; Bajcsy, J.; Gómez Barquero, David; Cardona Marcet, Narciso (Institute of Electrical and Electronics Engineers (IEEE), 2015-09)

To cope with increasing demands for spectral efficiency, multiple-input multiple-output (MIMO) technology is being considered for next generation terrestrial broadcasting television systems. In this paper, we propose a ...
A Novel Physical Layer Split FEC Scheme for Long Time Interleaving with Fast Zapping Support

Gómez Barquero, David; Gómez Molina, Pedro Fernando; Gozálvez Serrano, David; Sayadi, Bessem; Roullet, Laurent (Institute of Electrical and Electronics Engineers (IEEE), 2012-06)

This paper describes a novel forward error correction (FEC) and time interleaving scheme, known as BB-iFEC (Base Band inter-burst FEC), aimed to provide long time interleaving with fast zapping support. BB-iFEC is a split ...
Advanced Network Planning for Time Frequency Slicing (TFS) Toward Enhanced Efficiency of the Next-Generation Terrestrial Broadcast Networks

Giménez Gandia, Jordi Joan; Stare, Erik; Bergsmark, Staffan; Gómez Barquero, David (Institute of Electrical and Electronics Engineers (IEEE), 2015-06)

The allocation of frequencies traditionally used by terrestrial broadcasting (digital dividend) to International Mobile Telecommunication is limiting the evolution of the digital terrestrial television (DTT) networks for ...
Combined time, frequency and space diversity in DVB-NGH

Gozálvez Serrano, David; Gómez Barquero, David; Vargas Paredero, David Eduardo; Cardona Marcet, Narciso (Institute of Electrical and Electronics Engineers (IEEE), 2013-12)

In this paper, we investigate the combined use of time, frequency, and space diversity in DVB-NGH, the next generation mobile broadcasting standard. Compared to current standards like DVB-H or DVB-SH, the largest improvement ...
Improved Spectrum Usage with Multi-RF Channel Aggregation Technologies for the Next-Generation Terrestrial Broadcasting

Giménez Gandia, Jordi Joan (Universitat Politècnica de València, 2015-07-01)

[EN] Next-generation terrestrial broadcasting targets at enhancing spectral efficiency to overcome the challenges derived from the spectrum shortage as a result of the progressive allocation of frequencies - the so-called ...
Non-Uniform Constellations for Next-Generation Digital Terrestrial Broadcast Systems

Fuentes Muela, Manuel (Universitat Politècnica de València, 2017-07-07)

Nowadays, the digital terrestrial television (DTT) market is characterized by the high capacity needed for high definition TV services. There is a need for an efficient use of the broadcast spectrum, which requires new ...
Rotated constellations for improved time and frequency diversity in DVB-NGH

Gozálvez Serrano, David; Giménez Gandia, Jordi Joan; Gómez Barquero, David; Cardona Marcet, Narciso (Institute of Electrical and Electronics Engineers (IEEE), 2013-06)

In this paper, we investigate the potential gains that can be obtained with rotated constellations in DVB-NGH, the next-generation mobile broadcasting standard. Rotated constellations exploit the concept of signal-space ...
Single Carrier OFDM for the Next Generation Mobile TV Standard DVB-NGH

Sánchez Palomino, Guillermo (Universitat Politècnica de València, 2013-06-13)

[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.
Technical Solutions for Local Service Insertion in DVB-NGH Single Frequency Networks

López Sánchez, Jaime; Zöllner, Jan; Atungsiri, Samuel; Stare, Erik; Gómez Barquero, David (Institute of Electrical and Electronics Engineers (IEEE), 2014-06)

Current digital terrestrial television networks make use of either single frequency networks (SFN) or multifrequency networks (MFN). These network topologies are not ideally suited for delivery of both global and local ...
Transmit and Receive Signal Processing for MIMO Terrestrial Broadcast Systems

Vargas Paredero, David Eduardo (Universitat Politècnica de València, 2016-06-17)

[EN] Multiple-Input Multiple-Output (MIMO) technology in Digital Terrestrial Television (DTT) networks has the potential to increase the spectral efficiency and improve network coverage to cope with the competition of ...
