Abstract

Bir demodülatör gönderilen sembölleri tasiyan bir çok yollu (ISI) kanal üzerinde çalisir. Demodülatör gönderilen bir diziyi temsil eden bir sinyal alir ve bir senkronizasyon noktasina karsilik gelen bir seçim örnekleme fazinda bir çikis örnegi olusturulur. Bir çok varsayim dizisini temsil eden bir çok varsayim örnegi olusturulur.Çikis örnegi bir çok ölçüm belirlemek ve en iyi ölçümü üreten varsayim dizisine dayanarak gönderilen her dizi için bir orijinal tahmin olusturmak için bir çok varsayim örnegi ile karsilastirilir. Varsayim örnekleri seçilen örnekleme fazinin öncesinde bir erken örnekleme fazinda alinan ve seçilen örnekleme sonrasinda bir geç örnekleme fazinda alinan örnekle, gönderilen sembölün ikinci tahmininin orijinal tahminden daha iyi bir ölçüm üretip üretmedigini belirlemek ve daha iyi bir ölçüm üreten ikinci tahmine göre senkronizasyon noktasini ayarlamak için karsilastirilir.
