                                        Bu çalışma, kaos kavramının haberleşme sistemleri
içerisindeki uygulama alanını ve bu alanda sıkça kullanılan kaotik modülasyon
ve demodülasyon tekniklerini içermektedir. Ayrıca bu çalışmada, kaos
karmaşıklığının sayısal modülasyon teknikleri içerisinde kullanılmasına yönelik
genel bir bakış özetlenmekle beraber bu alanda özellikle üzerinde çalışılan
modülasyon tekniklerinden: Korelasyon gecikmeli kaydırmalı anahtarlama (KGKA),
frekans modülasyonlu farksal kaos kaydırmalı anahtarlama (FM-FKKA) ve kaotik
açma-kapama anahtarlama (KAKA) yapıları Simulink ortamında modellenmiş ve
benzetilmiştir. Modellere ait benzetim sonunda elde edilen teorik ve deneysel
sonuçlar tatmin edici seviyede olup bu sonuçlar ayrıca kaos tabanlı modülasyon
tekniklerinin sayısal haberleşme sistemlerinde pratik uygulamalarda kullanılabilirliğini
destekler niteliktedir. Kaos dinamiğinin sergilediği gürültü benzeri davranış
ve mevcut karmaşıklık düşünüldüğünde bu kavramın güvenli veri iletişimine
alternatif bir yaklaşım getirdiği, Simulink ortamında gerçekleştirilen benzetim
sonuçlarıyla da değerlendirilebilir.
