In this tvork, the fire fly algorithm which is a new metu-heuristic algorithm, is proposed to determine the CP length, By using the proposed algorithm, the better bit error rate in comparison with Genetic Algorithms and 1/8 rate cyclic prefix systems was obtained. Due to the less parameters and high performance of this algorithm over Genetic Algorithms; it can he used in multi currier cock division multiplexing systems to determine the cyclic prefix length adoptively.trinfo:eu-repo/semantics/openAccessMC-CDMACyclic prefixFire fly algorithmGenetic algorithmsArticle23548649110.5505/pajes.2016.04764trdizinikyokturWOS:000443170500001N/A
