Abstract

Bir otokorelasyon hesaplama birimi (21) bir girdi sinyalinden bir otokorelasyon RO(i) hesaplar. Bir tahmin katsayısı hesaplama birimi (23), bir katsayı wO(i) ile otokorelasyon RO(i)'nin çarpılması ile elde edilen modifiye otokorelasyon R'O(i)'yi kullanılarak doğrusal tahmin analizini gerçekleştirir. Burada, en azından bazı i derecelerinin her bir i derecesi için, i derecesine karşılık gelen wO(i) katsayısının, mevcut çerçevenin veya geçmiş bir çerçevenin girdi zaman serisi sinyalinin bir temel frekansı ile negatif bir korelasyona sahip olan bir değerdeki bir artış ile monoton olarak artan bir ilişkide içinde olduğu varsayılır.
