The main advantage of OFDM over single-carrier schemes is its ability to cope with severe channel conditions (for example, attenuation of high frequencies in a long copper wire, narrowband interference and frequency-selective fading due to multipath) without the need for complex equalization filters.
Read moreWhy OFDM is used in LTE?
Using multiple carriers, each carrying a low data rate, OFDM is ideal for high speed data transmission because it provides resilience against narrow band fading that occurs as a result of reflections and the general propagation properties at these frequencies .

OFDMA , “ODFM” adı verilen dijital modülasyon teknolojisinin çok kullanıcılı versiyonudur. Wi-Fi 6’da (802.11ax), OFDMA ağ performansını geliştiren en önemli özelliklerden biridir. OFDM ve OFDMA , aktarılan verileri birkaç küçük pakete bölerek küçük miktarda bilgilerin basit bir şekilde iletilmesini sağlar.
Read moreOFDM nedir ne amaçla kullanılır?
OFDM (Orthogonal Frequency Division Multiplexing) – Ortogonal Frekans Bölmeli Çoklama, Yayılı Spektrum’dan daha verimli bir teknolojidir. Bir sinyalin, birçok küçük sinyale bölünerek farklı frekanslarda ve eş zamanlı olarak gönderilmesidir. Yüksek aktarım kapasitesine ihtiyaç duyulan durumlarda kullanılır .
Read moreIs OFDMA a modulation?
Unsourced material may be challenged and removed. Orthogonal frequency-division multiple access (OFDMA) is a multi-user version of the popular orthogonal frequency-division multiplexing (OFDM) digital modulation scheme . Multiple access is achieved in OFDMA by assigning subsets of subcarriers to individual users.
