Abstract geometric optimization method of constellation based on genetic algorithm for multi-level mitigation of nonlinear effects.The new method of geometric optimization of constellation based on genetic algorithm for multi-level mitigation of nonlinear effects, which is applicable to the constellation multilevel m - QAM (quadrature amplitude modulation) in optical communications, based on the use of a algorit Mo optimizer and with the advantage that it can be applied to any type of channel, including nonlinear channels,As is the case of the optical fiber, after the establishment of the optical link, even before the use of channel by the user. In this proposal, the genetic algorithm varies the geometry of the constellation will be transmitted and monitors its bit error rate.In this method, after the steps of selection, crossover and mutation, the algorithm converges to an optimal solution globally, with a format of the constellation that expresses the lower BER (bit error rate or bit wrong). The objective of this solution is to optimize the constellations, especially for nonlinear channels, where the constellations and stars equally cease to be great. 1 / 1
