Determination of the cyclic prefix length in MC-CDMA using firefly algorithm

By Muhammet Nuri Seyman

Abstract

WOS: 000443170500001Cyclic prefix is utilized to prevent intermho) interference and inter currier interference M multi currier communication,systems such us multi -carrier code division multiple access that provides high speed data transmission, Therefore determination of the cyclic prefix Length properly, not only increases the error performance but also prevents the reduction in symbol energy. 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
