5G mobil aloqa tizimlarida ofdm texnologiyasining afzalliklari va samaradorligi
Abstract
Ushbu maqolada 5G mobil aloqa tizimlarida OFDM texnologiyasining ishlash prinsipi, uning spektral samaradorligi, ko‘p yo‘lli tarqalish sharoitidagi afzalliklari, MIMO va beamforming bilan integratsiyasi, yuqori ma’lumot uzatish tezligiga ta’siri hamda amaliy cheklovlari tahlil qilinadi. Shuningdek, radioresurslarni rejalashtirish, PAPR, sinxronlash, subtashuvchi oralig‘ini tanlash va 4G hamda 5G tarmoqlaridagi qo‘llanish xususiyatlari ham yoritiladi.
Kalit so‘zlar: mobil aloqa, 5G, LTE, OFDM, OFDMA, radioresurs, spektr samaradorligi, MIMO, beamforming, PAPR, subtashuvchi, IoT
