Yardımcı Pilot Sembolleri ve Kodlama Tekniklerini Kullanan FBMC Dalga Formu Yapısı ile OFDM Sisteminin Kıyaslanması
Öz
Yeni nesil haberleşme
sistemleri olarak bilinen 5G haberleşme sistemlerinde FBMC yapısı önemli bir
gelişme göstermiş literatürde çoğunlukla tercih edilen OFDM yapısının aksine
çok daha iyi spektral özellikler sağlamaktadır. Haberleşme sistemlerinde veri
iletimi için önemli rol oynayan kanal durum bilgisi gereksiniminin giderilmesi
nedeniyle kanal tahmini yöntemlerine başvurulmaktadır. FBMC yapısı için bu
çalışmada pilot sembol destekli kanal tahmini, kodlama ve yardımcı pilot sembol
yöntemleri kullanılmıştır. Literatürde
büyük yer tutan OFDM ve FBMC yapıları kullanılarak yapılan modülasyon
işlemlerinde bu iki tekniğin birbirlerine göre avantaj ve dezavantajları
incelenmiş bit hata olasılığı, ortalama gücün tepe güce oranı, iletim güçleri,
güç spektral yoğunluğu, kapasite artışı gibi parametreler bakımından karşılaştırmaları
gerçekleştirilmiştir. Ayrıca uygulamalar farklı kanal modelleri için
yenilenerek farklı kanalların etkisi de ortaya konulmuştur.
