Artigo Completo:

Esse artigo apresenta uma abordagem multiobjetivo e multirestrição para a otimização de sistemas de transmissão de vídeo digital, baseados em Redes de FrequÊncia Única. O método proposto é capaz de prover curvas de compromisso para a cobertura, custos e interferências, entre outros como nível de exposição à radiação. O método de otimização de cobertura geral proposto pode ser estendido a outras redes sem fio, como sistemas de celular.

Artigo Completo:

This paper presents a multi-objective multi-constraint approach for optimization of Digital Video Broadcasting (DVB) systems based on Single Frequency Networks (SFN). The proposed method is capable of providing the trade-off curves of coverage, costs, and interference, besides others as exposure to radiation level. The proposed general coverage optimization method can be extended to other wireless networks, such as cellular systems.
