In this work, we propose a threshold allocation optimization process carried out by a genetic algorithm (GA) in order to optimize the CPWL model (GA-CPWL). Firstly, experiments show how the CPWL model outperforms the classical memory polynomial DPD in an intensity modulation/direct detection (IM/DD) RoF link. Then, the GA-CPWL predistorter is compared with the CPWL model in several scenarios, in order to verify that the proposed DPD offers better performance in different optical transmission conditions. Experimental results reveal that with a proper threshold allocation, the GA-CPWL predistorter offers very promising outcomes. 000060717 536__ $$9info:eu-repo/grantAgreement/ES/DGA/GCM-T97$$9info:eu-repo/grantAgreement/ES/MINECO/TEC2014-58341-C4-2-R 000060717 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000060717 590__ $$a3.356$$b2017 000060717 591__ $$aOPTICS$$b19 / 93 = 0.204$$c2017$$dQ1$$eT1 000060717 592__ $$a1.519$$b2017 000060717 593__ $$aAtomic and Molecular Physics, and Optics$$c2017$$dQ1 000060717 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000060717 700__ $$0(orcid)0000-0001-5849-5198$$aCarro, P.L.$$uUniversidad de Zaragoza 000060717 700__ $$0(orcid)0000-0002-7452-446X$$aGarcía-Dúcar, P.$$uUniversidad de Zaragoza 000060717 700__ $$0(orcid)0000-0002-2796-5916$$aMingo, J. de$$uUniversidad de Zaragoza 000060717 700__ $$0(orcid)0000-0002-6144-7928$$aSalinas, I.$$uUniversidad de Zaragoza 000060717 7102_ $$15008$$2800$$aUniversidad de Zaragoza$$bDpto.
