digital equalizer with flexible architecture for digital optical communications systems

摘要

The present invention describes a new digital equalizer with flexible architecture for digital optical communications systems, which is an equalizer that has a flexible architecture that allows the configuration of the length of the equalizer overlap according to the channel memory, with consequent energy saving. Where the length of the overlap is adjusted, according to the characteristics of the channel, in particular the chromatic dispersion value that must be compensated by the digital equalizer, making use of variable overlap by inserting an input recorder and a digital equalizer in the digital equalizer. output recorder, both operating in queue regime, and both operating with different input and output clocks, obtaining a variation in the frequency of operation of the equalizer that changes the number of operations per second, resulting in an impact on energy consumption.
