Abstract

Bu buluşta, kaynak sayısı ve bunlara ait geliş açısını (DOA) ortak bir şekilde alıcı dizileriyle sezmek ve kestirmek içın yöntem ve ona ait aygıt açıklanmaktadır. Yöntem, DOA'lan verilen bir derece n için MUSIC, root-MUSIC veya ESPRIT algontmaları gibi uygun bir algoritma vasıtasıyla bulmaktadır. Ardından dizi manifold matrisi oluşturulmakta ve seçilmiş olan kaynak sayısı için bir hata bulunmaktadır, n için n=l, ,nmax olmak üzere değerier verilmekte ve hata e(n) her seferinde hesaplanmaktadır. Hata terimi deterministik veya istatistiksel en büyük olabilirlik fonksiyonu kullanılarak hesaplanmaktadır. Kaynak sayısı, hata fonksiyonunun f(e(n)) aldığı en küçük değere karşı gelen n değeri olarak bulunmaktadır. DOA'lar daha once bulunduğu için, hem kaynak sayısı hem de bunlara ait DOA'lar ortak olarak bulunmaktadır.
