An approach that predicts the propagation, models the terrestrial receivers and optimizes the performance of single frequency networks (SFN) for digital video broadcasting in terms of the final coverage achieved over any geographical region, enhancing the most populated areas, is proposed in this paper. The effective coverage improvement and thus, the self-interference reduction in the SFN is accomplished...
This paper presents and compares different configurations of several heuristic optimization methods with the aim of seeking the one with the best performance when applied to phase synthesis of reflectarray antennas. This phase synthesis is a hard task and improving the synthesis method can result in significant reductions in the associated computational cost. The performance of algorithms such as...
Terrestrial digital broadcasting networks for digital video broadcasting (DVB) systems, such as DVB-T or DVB-T2, can be either multi-frequency (MFN) or single frequency (SFN). Regarding the SFN, the use of the spectrum is more efficient, and receiving locations can be served by several transmitters working at the same frequency. Moreover, DVB receivers based on OFDM modulation schemes can succeed...
