Ushbu maqolada axborot uzatish tizimlarida xatolarga chidamlilikni oshirish maqsadida BCH va Xeming kodlarini birlashtirgan gibrid kaskadli kodlash usuli tadqiq etiladi. Tadqiqotning asosiy g'oyasi — Xeming kodining kam resurs talab qilishi va BCH kodining ko'p sonli xatolarni tuzatish imkoniyatlaridan kombinatsiyalashgan holda foydalanishdir. Maqolada kaskadli tizimning strukturaviy sxemasi ishlab chiqilgan va turli darajadagi shovqinli kanallarda xatolarni tuzatish koeffitsiyenti tahlil qilingan. Natijalar shuni ko‘rsatadiki, taklif etilayotgan gibrid usul individual kodlash usullariga qaraganda ma’lumotlarning butunligini ta’minlashda yuqori samaradorlik ko‘rsatadi.
