What is OFDM? Orthogonal frequency-division multiplexing ( OFDM ) is a method of encoding digital data on multiple carrier frequencies. OFDM has developed into a popular scheme for wide band digital communication , used in applications such as digital television and audio broadcasting, DSL Internet access , wireless networks , power line network , and 4G mobile communications. Orthogonal Frequency Division Multiplexing or OFDM is a modulation format that is being used for many of the latest wireless and telecommunications standards. OFDM has been adopted in the Wi-Fi arena where the standards like 802.11a, 802.11n, 802.11ac and more. It has also been chosen for the cellular telecommunications standard LTE / LTE-A, and in addition to this it has been adopted by other standards such as WiMAX and many more. Although OFDM, orthogonal frequency division multiplexing is more comp...
