Ushbu maqolada optik aloqa tizimlarida axborotni kodlash usullarining
samaradorligini oshirishga qaratilgan zamonaviy texnologiyalar tahlil qilinadi. Optik
tarmoqlarda ma’lumot uzatish tezligi, ishonchliligi va shovqinlarga barqarorlik
talablarining ortib borishi kodlash algoritmlarini optimallashtirishni dolzarb masalaga
aylantirmoqda. Tadqiqotda ilg‘or kanal kodlash yondashuvlari – xatolarni tuzatish
(FEC) texnologiyalari, kodlangan modulyatsiya, LDPC va polar kodlar – ko‘rib
chiqilib, ularning uzatish sifati, spektral samaradorlik va tizim sig‘imiga ta’siri tahlil
etiladi. Shuningdek, kodlash usullarining zamonaviy optik modulyatsiya texnikalari
bilan integratsiyalashuvi natijasida xatolarga chidamlilik va ishlash ko‘rsatkichlari
qanday yaxshilanishi asoslab beriladi. Tadqiqot natijalari optimallashtirilgan kodlash
strategiyalari optik aloqa tizimlari samaradorligini sezilarli darajada oshirishini
ko‘rsatadi.
