3.7- rasmlarda OFDM texnologiyasining natijalari

III-Bob bo‘yicha xulosa
Simsiz tarmoqlarda fizik ma'lumotlarni uzatish tezligini oshirishning muhim vositasi spektral kanallarning kengligini kengaytirishdir. Multiphoning (MURDM) ma'lumotlarni uzatishning ortogonal chastotali bo'linish bilan ajratilgan kengroq kanaldan foydalanish orqali maksimal ko'rsatkichlar bilan amalga oshiriladi. OFDM - bu WiMax / WiFi tarmoqlarida bayririylik sarmoyaviy ravishda simsiz simsiz ma'lumotlarni uzatish vositasi sifatida juda yaxshi isbotlangan raqamli mododlam. Kanallarning o'tkazish qobiliyatini kengaytirish usuli iqtisodiy jihatdan samarali va raqamli signalni qayta ishlash (DSP) ning o'rtacha o'sishi bilan adolatli amalga oshiriladi. To'g'ri foydalanish bilan siz Wi-Fi 802.11 standartini 40 MGts kanalidan 40 MGts-ga etkazish chastotasini ikki baravar oshirishingiz mumkin, siz hozirda ishlatilgan kanallarning kuchli tomonlaridan ko'proq narsani ta'minlashingiz mumkin. MIMO arxitekturasining keng kanalli keng kanalli keng kanalli va jismoniy uzatish stavkasini oshirishga juda kuchli va iqtisodiy munosib yondashuvga sabab bo'ladi.
