Son yıllarda haberleşme teknolojilerindeki hızlı gelişmeler nedeniyle kablosuz iletişim ön plana çıkmıştır ve hızla gelişmektedir. Kablosuz iletişim bütün avantajlarının yanında bazı zorluklara da sahiptir. Kablosuz haberleşmede karşılaşılan esas problem sinyalde meydana gelen sönümlü kanal etkisidir. Sönümlü kanal etkisi, sinyalde zaman ve frekans yayılmasına bağlı olarak sınıflandırılır. Bu sınıflandırma, zamansal yayılmaya bağlı olarak frekans seçici sönümlenme ve düz sönümlenme olarak meydana gelirken, frekans yayılmasına bağlı olarak da hızlı sönümlenme ve yavaş sönümlenme olarak meydana gelir. Bu çalışmada sinyal bileşenlerinde görülen zaman ve frekans yayılmasına bağlı sönümlü kanal etkisi Rayleigh ve Rician sönümlü kanal modelleri i...
