Optimization of the Digital Terrestrial Television Transmission Mode of DVB-T2 in Colombia [PDF]
In December 2011, Colombia updated its national Digital Terrestrial Television (DTT) standard from DVB-T to DVB-T2, the second generation of the DVB (Digital Video Broadcasting) project. DVB-T2 is the current state-of-the art DTT system in the world, and

This study investigated the changes of the volatile compounds in orange and tangor peels and the essential oils prepared using different extraction methods: hydrodistillation and cold pressing. We provide comprehensive data on essential oils, especially those derived from oranges and tangors, to aid in selection of the appropriate extraction method for

Spectral Overlap Optimization for DVB-T2 and LTE Coexistence [PDF]
In this paper, we analyze the spectral coexistence between the second generation terrestrial digital video broadcasting (DVB) and the long term evolution (LTE) networks. In particular, the global spectral efficiency (SE) of both systems is investigated when a partial spectral overlap between DVB and LTE signals occurs. Our contribution lies in twofold:

OFDM comparison with FFT and DWT processing for DVB-T2 wireless channels
Introduction: Recent studies on the FFT processing (Fast Fourier Transform) or DWT (Discrete Wavelet Transform) of the OFDM signal (Orthogonal Frequency Division Multiplexing) have shown pros and cons for DVB-T2 (Digital Video Broadcasting-Second ...
