Orthogonal frequency division multiplexing (OFDM) has grown to be the most popular communications system in high-speed communications in the last decade. In fact, it has been said by many industry leaders that OFDM technology is the future of wireless communications, as we know it. This paper will give a brief history of the evolution of OFDM, highlighting the specific advantages of this technology in high-speed, two-way communications. It will explain the common implementations of OFDM and discuss OFDM's potential as a standard for various high-speed applications.
