Abstract

Bir iletisim sisteminde ortogonal hiza bagimli walsh gizleme kodlarini kullanarak hiz belirlemesi için bir yöntem ve tertibat. Ortogonal hiza bagimli walsh kodlari bir iletisim hatti üzerinden iletilmeden önce yinelenen kod simgelerini gizlemek için kullanilir. Walsh kodlari sistemdeki her veri hizi için iki üssü artan ortogonal ikili kodlardan olusur. Kod simgeleri yinelenir ve sonra bulusun walsh kodlari kullanilarak simge hizinda gizlenir. Simge hata orani (SER) bloklari aday hizlarin her biri için hiza bagimli SER ölçütleri üretmek için kullanilir. Yanlis veri hizi hipotezlerini kullanan yumusak birlestiricilerle iliskili SER tahmincileri, dogru hiz hipotezini kullanan yumusak birlestiriciyle iliskili SER tahmincisi tarafindan üretilen simge hata oranindan yüksek simge hata oranlari üretir.
