The transmitter stage of an OFDM transceiver takes data from a source, converts and encodes it into a serial stream before modulation. A combination of the long symbol period and a guard interval between symbols reduces any Inter Symbol Interference to very insignificant proportions. It is a form of a multi-carrier modulation (MCM) where a sub-carrier within each frequency band is modulated separately to carry a portion of the user information. OFDM is a method that allows transmitting high data rates over extremely hostile channels at a relatively low complexity. It has been adopted as the transmission technology for various wireless standards. Orthogonal Frequency Division Multiplex (OFDM) has gained considerable attention in recent years.
