Abstract
Söz konusu bulus dijital alicilar ve yumusak aktarim esnasinda trafik ve pilot kanallarinin göreli kuvvetlerini ölçekleyen alma yöntemleri ile ilgilidir. Bulusa uygun olarak trafik ve pilot kanallarina ait yayili spektrum sinyalleri, trafik ve pilot kanallarindan alinan veri örnekleri kullanilarak islenirler. Alinan bu veri örneklerinden bilgi sembollerine tekabül eden istatistiksel bulgular elde edilir. Söz konusu istatiksel bulgular trafik ve pilot kanallarinin göreli kuvvetleri de hasaba katilarak Rake birlestirmesi yapilarak olusturulur.
