Abstract

Kanal tahmini bir radyo sinyalinin alinmis alistirma sirasi kismi alinip, alinmis alistirma sirasi ve önceden belirlenmis bir alistirma sirasi temelinde birçok kanal modeli yapisi tahmin edilerek yapilir. Kanal modeli yapilarinin her biri için, karsilik gelen katsayilar karsilik gelen kanal modeli yapisiyla iliskili olan ve baska hiçbiriyle iliskili olmayan bir grup bir veya daha fazla kilavuzun tümü kullanilarak belirlenir. Her kanal modeli yapisi için, kanal modeli yapisi tarafindan üretilen tahmini bir deger ile alinmis bir sinyal degeri arasindaki varyansin miktarini temsil eden bir varyans ölçümü üretilir. Varyans ölçümleri temelinde kanal modeli yapilarindan bir optimum kanal modeli yapisi seçilir ve optimum kanal modeli yapisiyla iliskili durumlarin sayisi üretilir.
