Abstract
Bir dogrudan dizi CDMA alicisi, örneklenmis bir sinyali alir. Alt-örnekleme ünitesi, yonga-örneklemli bir sinyalin üretilmesi için zamanlama bilgisine uygun olarak örneklenmis sinyalin alt-örneklemini saglar. Bir esdeger kod üretici, zamanlama bilgisini ve kullanicinin yayilma kodlarina iliskin bilgiyi kullanarak esdeger kodlar üretir. Bir islemci, dikeylestirilmis bir kodun üretilmesi için esdeger kodlari islemden geçirir ve bir korelatör, bir yayilma giderme degerinin üretilmesi için yonga-örneklemli sinyal ile dikeylestirilmis kod arasinda korelasyon saglar.
