Ushbu maqolada radiokanallardagi shovqin tufayli signal sifatining pasayishi va bit xato darajasi ning oshishi muammosi tahlil qilindi. Shovqin manbalari sifatida termik shovqin, atmosferik shovqin, interferensiya va ko‘p yo‘lli tarqalish effekti ko‘rib chiqilgan. Muammoni yechish uchun matematik modellashtirish, filtrlar va sun’iy intellekt modellaridan foydalanish asosida shovqinli nochiziqli signalini tozalash va original signalni tiklash jarayoni tahlil qilingan. Shovqinli raqamli signalni qayta ishlash va uning sifat ko‘rsatkichlarini yaxshilash maqsadida 1D CNN modeliga asoslangan dasturiy yechim ishlab chiqilgan. Modelning tuzilishi, o‘qitish bosqichlari hamda signalni filtrlash jarayonidagi vizual va miqdoriy natijalari tahlil qilingan. O‘tkazilgan tajribalar asosida taklif etilgan yondashuv bit xato darajasini sezilarli kamaytirishi va radio, mobil aloqa tizimlarida signal sifati oshishiga xizmat qilishimumkinligini keltirilgan.
