Keywords:
MCS, signal-shovqin nisbati, IEEE 802.11, simsiz tarmoqlar, uzatish tezligini moslashtirish, kadrlar yo‘qotilishi, Markov zanjiri, kanal sifati, modulyatsiya, kodlash sxemasiAbstract
Ushbu ilmiy ishda IEEE 802.11 standart tarmoqlari samaradorligini yanada chuqurroq tahlil qilish va baholash maqsadida yangi, takomillashtirilgan IEEE 802.11n/ac kanal modeli ishlab chiqiladi. Mavjud modellarning cheklovlari va zaif tomonlari o‘rganilib, ularning asosida real sharoitlarga yaqinroq bo‘lgan, yuqori aniqlikda ishlovchi kanal modeli taklif etiladi. Yangi model yordamida turli sharoitlarda Wi-Fi tarmog‘ining ishlash ko‘rsatkichlari – ya’ni, ma’lumot uzatish tezligi, signal sifati, uzilishlar va tarmoqli kengligi samaradorligi aniq tahlil qilinadi. Model simulyatsiya orqali sinovdan o‘tkazilib, amaliy qo‘llash imkoniyatlari baholanadi. Ushbu ish natijalari IEEE 802.11 asosidagi simsiz tarmoqlarni yanada ishonchli va samarali qilishda muhim ilmiy-amaliy asos bo‘lib xizmat qiladi
