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.
Read moreIs OFDMA FDMA technique?
1 Comparison of FDMA and OFDM signals; (a) five FDMA channels with guard band and (b) 5 OFDM orthogonal channels. Orthogonal frequency division multiplexing (OFDM) is a communication technique that can be seen as either a modulation scheme or a multiplexing technique .
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.
