Compensação do Efeito da Variação da SOP em Técnica de Monitoração de OSNR via DSP

The effect of variation in the state of polarization (SOP) in the non coherent signals modulated by OOK 40Gbps was considered in this work to estimate the OSNR through polarization diversity and digital signal processing technique. Through a characterization of this effect, its influence is compensated and a high accuracy is achieved for OSNR monitoring
