What does OFDM stand for?
Orthogonal Frequency Division Multiplexing (OFDM) is a digital transmission techniques that ultilizes large numbers of carriesr spaced apart at slightly different frequencies. OFDM is used in many wireless application including Wi-Fi, digital radio and TV broadcasting in Europe and Japan and UWB. (Souce: EE Times)
