Karma Weibull/Log-Normal Sönümlenmeli Kanalın Hata Olasılığı Analizi

Bu çalışmada, tek-girişli tek-çıkışlı (single-input single-output, SISO) sistemin karma Weibull/log-normal sönümlenmeli kanallardaki hata olasılığı incelenmiştir. Ele alınan SISO sisteminin daha gerçekçi bir kanal ortamında analizinin yapılması hedeflenmiştir. Bu yüzden, Weibull/log-normal sönümlenmeli kanalının kümülatif dağılım fonksiyonu (cumulative distribution function, CDF) kullanılarak hata olasılığı ifadesi kapalı formda elde edilmiştir. Önerilen bu ifade CDF tabanlı olup, farklı ikili sayısal modülasyon türleri için geçerlidir. Çalışmada sunulan bütün sonuçlar bilgisayar benzetimleri ile doğrulanmıştır.
