Bu çalışmada, frekans çözünürlüğünün (yankı çözünürlüğünün) R-MUSIC (Root-MUSIC, Çoklu Sinyal Sınıflandırma) ve ESPRIT (Rotasyonel Değişmezlik Tekniği ile İşaret Parametrelerinin Kestirimi) yöntemleri kullanılarak nasıl değiştiği incelenmiştir. Bu yöntemler, girişimli kanal verisine uygulanmıştır [1]. Az yankılı ve orta yankılı iki kanal verisi yöntemlerin başarımını incelemek için seçilmiştir. Aynı model değişkenleri için R-MUSIC yönteminin, ESPRIT yöntemine göre daha iyi sonuç verdiği ve 1.5 katlık yankı çözünürlüğü iyileşmesi sağladığı görülmüştür.
