Study of OFDM System for Application of Wireless Communication

OFDM is Orthogonal Frequency Division Multiplexing. This multiplexing technique use for many of the latest wireless and telecommunication standards. OFDM split wideband signal into narrowband signal for transmission. The transmission of these individual narrow band signal are executed with orthogonal carriers utilize this approach achieving high data rate transmission without ISI and high spectral efficiency requirement for wireless communication. In this paper discuss basic system of OFDM is gaining a wide spread popularity within the wireless transmission. The research paper focus on basic principle of OFDM and also discuss OFDM based UWB approach. finally the paper provide a number of wireless application where OFDM used and its advantages and disadvantages.
