Abstract

Bu çalışmada, ikili haberleşme sistemleri simetrik Gauss karışım gürültülü kanal için çalışılmaktadır. Tek eşik sezici ile optimal olan ML kurallı sezici hata olasılıkları açısından karşılaştırılmaktadır. İlk olarak, tek eşik sezicinin optimal olduğu yeter koşul elde edilmektedir. Tek eşik sezici gürültüsüz koşullarda bile düşük performans gösterebileceğinden, ortalama hata olasılığının sıfır olduğu ML sezici için yeterli koşullar sunulmaktadır. Kuramsal sonuçları doğrulamak amacıyla çeşitli senaryolar için sayısal örnekler sunulmaktadır.
