Abstract
Konfor gürültüsü fonksiyonlari, radyoiletisim sistemlerinde mikrofonlarin aldigi zemin gürültüsünü izler. Bu fonksiyonlar, sessizlik sürelerinde uzak üniteler tarafindan iletilen konfor gürültüsü bilgisini saglar, bu sekilde alici tarafin donanimi, uygun zemin gürültüsünün çikisini yaparken, verici taraf, güç korunumunun saglanmasi için iletim devresini çalismaz hale getirebilir. Ses kisma fonksiyonlarinin uyumu, zemin gürültüsünün sürekli olarak izlenmesini saglayacak sekilde konfor gürültüsü fonksiyonlarina sinyaller saglamayi sürdürerek saglanir. Uzak ünitenin ses kisma modu çalistirildiginda, verici, bir ses (konusma) kodlayicisindan çikan bilgi çikisi yerine konfor gürültüsü kayit birimlerini veya sessizlik kayit birimlerini alir.
