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 moreWhat is OFDM technique?
Orthogonal frequency-division multiplexing is a method of data transmission where a single information stream is split among several closely spaced narrowband subchannel frequencies instead of a single Wideband channel frequency .
Read moreIs OFDMA multiplexing technique?
Conceptually, OFDM is a specialized frequency-division multiplexing (FDM) method , with the additional constraint that all subcarrier signals within a communication channel are orthogonal to one another.
