In the OFDM (Orthogonal Frequency Division Multiplexing) system, the fast synchronization is required which in general could be achieved using the preamble located in the header part of the data packet. The modulated and transmitted signal experiences the frequency selective fading due to the multipath channel. As the recent OFDM systems have been applied to the various application areas, the coverage increases which can be translated into the wide range of the signal power variation observed at the receiver side.
