Transmissão de Sinais Ópticos em Banda Lateral Única, com Igualação no Domínio ...
Edgardo Costa; António Pinho; Paulo Monteiro; Rui Ribeiro; J. Ferreira da Rocha; Tiago MaiaIn this article is investigated an optical single sideband transmission system at 10 Gbit/s with electrical equalization, using the zero forcing criteria, to compensate the chromatic dispersion. The optical transmission of single sideband signals increases the transmission distances relative to the transmission in double sideband (DSB) form.Simulation results also showed that using this...
Optimization of an Optical Single Sideband Transmitter
Tiago Maia; Rui Ribeiro; Paulo MonteiroThe interest in single sideband modulation for transmission of digital data along optical fibers is growing, since it allows an improvement on the signal spectral efficiency and a reduction on the distortion produced by the fiber chromatic dispersion.In the optical single sideband transmitter the influence of the Hilbert filter configuration and the modulation depth were analysed i...

The post-transcriptional gene silencing pathway in Eucalyptus
Sassaki,Flávio Tetsuo; Campos-Pereira,Tiago; Maia,Ivan de GodoyPost-transcriptional gene silencing (PTGS) is a conserved surveillance mechanism that identifies and cleaves double-stranded RNA molecules and their cellular cognate transcripts. The RNA silencing response is actually used as a powerful technique (named RNA interference) for potent and specific inhibition of gene expression in several organisms. To identify gene products in Eucalyptus sharing similarities with ...
