摘要

The use of genetic algorithms to explore the finite precision in algorithms for coherent optical systems, which refers to a methodology based on meta heuristic for the definition of the finite representation of algorithms of digital signal processing applied to systems. Optical.In the stage of search, these algorithms are designed with the aim of increasing the spectral efficiency, the margin systemic and mitigate the effects associated to the channel, in case the optical fiber. During its design, usually uses a language with a high degree of abstraction with the resources to describe mathematical operations necessary to the treatment of the data.To solve the problem of optimization to find the minimum size of the variables of an algorithm keeping their systemic response, at a time, proposed the use of genetic algorithm (GA).This approach considers that has already been carried out a preliminary study considering several other factors, such as area, power dissipation, latency and others, so that they are not in the scope of the present invention another metric that is not the reduction of quantization and restored In the system, and thus the time to find an optimal solution or near optimal will be reduced.
