Abstract

Cyclic prefix is utilized to prevent inter symbol interference and inter carrier interference in multi carrier communication systems such as 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 work, the fire fly algorithm which is a new meta-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 be used in multi carrier code division multiplexing systems to determine the cyclic prefix length adaptively.

Özet

Çok taşıyıcılı kod bölmeli çoklu erişim gibi yüksek hızlarda veri iletimini sağlayan çok taşıyıcılı haberleşme sistemlerinde semboller arası girişim ve kanallar arası girişimi önlemek için çevrimsel ön takıdan faydalanılır. Bu yüzden çevrimsel ön takı uzunluğunun uygun bir şekilde belirlenmesi, sadece hata performansını artırmayacak aynı zamanda da sembol enerjisindeki azaltmaları da engelleyecektir. Bu çalışmada çevrimsel ön takı uzunluklarının belirlenmesi için yeni bir meta-sezgisel algoritma olan ateş böceği algoritması önerilmiştir. Önerilen bu algoritmayı kullanarak, Genetik Algoritmalar ve 1/8 oranlı çevrimsel ön takı kod uzunluklu sistemlere göre daha iyi bit hata oranları elde edilmiştir. Parametre sayısının az ve performansının Genetik Algoritmalara göre yüksek olması nedeniyle bu algoritma çok taşıyıcılı kod bölmeli çoklu erişim sistemlerinde çevrimsel ön takı boyutlarının adaptif olarak belirlenmesinde kullanılabilir.
