(pronounced as separate letters) Short for Orthogonal Frequency Division Multiplexing, an FDM modulation technique for transmitting large amounts of digital data over a radio wave. OFDM works by splitting the radio signal into multiple smaller sub-signals that are then transmitted simultaneously at different frequencies to the receiver. OFDM reduces the amount of crosstalk in signal transmissions. 802.11a WLAN, 802.16 and WiMAX technologies use OFDM. Compare with FHSS and DSSS.

The Suitability of OFDM As a Modulation Technique for Wireless Telecommunications This thesis investigates the effectiveness of Orthogonal Frequency Division Multiplexing (OFDM) as a modulation technique for wireless radio applications. Tools Simplify 802.11 Deployments Wireless LAN installation is tricky. The construction of a facility and silent sources of RF interference impact the propagation of radio waves, often in odd ways.
