Abstract

Bir iletisim kanal bilesenlerinin, örnegin bir uydu iletisimimdeki transponderin özelliklerinin belirlenmesi için sahte bir parazit sinyali PN(t) ile temiz tasiyici bir sinyal f(t) modüle edilir ve es zamanli olarak iletisim kanali yoluyla iletilen faydali yük sinyali düzeyinin altindaki bir düzeyde iletisim kanali yoluyla iletilir. Alinan sinyal s'(t), geri kazanilmis tasiyici bir sinyal F' (t) elde etmek için ayni sahte parazit sinyaline PN(t) baglanir. Hem temiz sinyal f(t) hem de geri kazanilan tasiyici sinyal f'(t), arzu edilen özelliklerin belirlenmesi için kullanilabilir. PN ile modüle edilmis temiz tasiyici sinyal s(t), düsük seviyede iletildigi için faydali yük sinyalini kapatmadan ölçümler yapmak mümkündür.
