Combined Time and Space Diversity: Mobile Reception in DVB-T and DVB-T2 Systems

Gozálvez Serrano, David; López Sánchez, Jaime; Gómez Barquero, David; Giménez Gandia, Jordi Joan; Cardona Marcet, Narciso (2012-12)

The simultaneous delivery of fixed and mobile services in digital terrestrial TV (DTT) networks is a very attractive concept, as it allows the reuse of content, spectrum, and infrastructure. However, the provision of mobile ...
Fading Margin Reduction due to Inter-Burst Upper Layer FEC in Terrestrial Mobile Broadcast Systems

Gómez Barquero, David; Gozálvez Serrano, David; Gómez Molina, Pedro Fernando; Cardona Marcet, Narciso (Institute of Electrical and Electronics Engineers (IEEE), 2011-09)

In this paper, we investigate the reduction of the shadowing fading margin that can be achieved with interburst upper layer forward error correction (UL-FEC) in terrestrial mobile broadcast systems with time slicing (i.e., ...
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 ...
Layer-Aware Forward Error Correction for Mobile Broadcast of Layered Media

Hellge, Cornelius; Gómez Barquero, David; Schierl, Thomas; Wiegand, Thomas (Institute of Electrical and Electronics Engineers (IEEE), 2011-06)

The bitstream structure of layered media formats such as scalable video coding (SVC) or multiview video coding (MVC) opens up new opportunities for their distribution in Mobile TV services. Features like graceful degradation ...
WiB a new system concept for digital terrestrial television (DTT)

Stare, E.; Giménez Gandia, Jordi Joan; Klenner, P. (Institution of Engineering and Technology, 2016)

[EN] A new system concept for DTT, called WiB , is presented, where potentially all frequencies within the Ultra High Frequency (UHF) band are used on all transmitter (TX) sites (i.e. reuse-1). The interference, especially ...
Wideband planar slotted radiating ground plane antenna for portable devices

Tapani Sonkki, Marko; Antonino Daviu, Eva; Ferrando Bataller, Miguel; Salonen, Erkki T. (Wiley-Blackwell, 2011-12)

A method for exciting currents in a radiating ground plane over a wide frequency bandwidth is presented. Using a complementary slot in the ground plane excited by a closely spaced monopole (0.008-0.05¿) with 50 Î© input ...
