Abstract
Birçok sembol içeren radyo frekansi sinyal burstunu alan ve her bir sinyal burstunun en az bir kompleks baz bandi sinyalini (I ve Q) olusturan bir homodin radyo alicisi düzenegidir. Bir DC dengeleyicisi, bahsedilen örneklerin bir ortalama DC-seviyesini belirleyen bir ortalama hesaplayicisi (8, 8') ve bahsedilen örneklerin birçogunun bir isaretli kare toplamini hesaplayan ve kare toplaminin bir dengeleme faktörü ile agirlikli bir kare toplami alan bir isaretli kare toplami hesaplayicisi (9, 9') içerir. Düzeltme araçlari (10, 10') bahsedilen ortalama hesaplayicisinin bir çiktisindan kare toplamini DC-seviyesi tahminini olusturmak için çikarir.
