Method of pre filtering to optimize spectral optical multichannel

摘要

Method of pre filtering optical multichannel spectral optimization.New method of pre filtering optical multichannel spectral optimization, which proposes that the profile of the filter using the pre emphasis signal is determined through a genetic algorithm, where the cost function to be minimized in the receipt is the BER (bit error rate. RRO of bit), and a programmable optical filter which is used in the filtering of signals.This method to optimize the detection signal the end of a link is mainly applied in optical links without repetition, not restricted to these; in the case of a method of reformatting of the spectrum of the signal so as to reduce the impact of non-linear effects in the signal via You 're the use of flexible optical filtering.By using an optical filter programmed to evaluate the performance of the system and a genetic algorithm that uses the BER in the reception function of cost to obtain the profile of the filter to optimize reception, where the use of genetic algorithm and realizes the otimizau00e7 multiobjetivo multidimensional With simultaneous multiple channels.In such a way, the optimization of multiple channels by means of a given sequence of individual optimizations is performed through the genetic algorithm for multidimensional and multiobjetivo in a sequence of optimization for individual channel specific.
