 مضاعفة الانقسام الترددي المتعامد Explanation:there should be a (dash) frequency-division Orthogonal frequency-division multiplexing (OFDM): تعريف (1) a method of digital modulation in which a signal is split into several narrowband channels at different frequencies (2) Orthogonal FDM's (OFDM) spread spectrum technique distributes the data over a large number of carriers that are spaced apart at precise frequencies. This spacing provides the "orthogonality" in this technique which prevents the demodulators from seeing frequencies other than their own http://searchnetworking.techtarget.com/sDefinition/0,,sid7_g... http://www.wave-report.com/tutorials/OFDM.htm

(تقسيم قناة الاتصال إلى حزم تردد مستقلة)

Orthogonal frequency division multiplexing (OFDM) is a communications technique that divides a communications channel into a number of equally spaced frequency bands. A subcarrier carrying a portion of the user information is transmitted in each band. Each subcarrier is orthogonal (independent of each other) with every other subcarrier, differentiating OFDM from the commonly used frequency division multiplexing (FDM). orthogonal frequency division multiplexing is a very effective way of protecting data transmitted over a communications channel that experiences narrow-band fading.

Orthogonal frequency-division multiplexing (OFDM): تعريف
(1) a method of digital modulation in which a signal is split into several narrowband channels at different frequencies

(2) Orthogonal FDM's (OFDM) spread spectrum technique distributes the data over a large number of carriers that are spaced apart at precise frequencies. This spacing provides the "orthogonality" in this technique which prevents the demodulators from seeing frequencies other than their own
