The aim of this paper is studying the Orthogonal Frequency Division Multiplexing (OFDM) system. The (OFDM) is a multi-transporter regulation system which is especially famous in new remote systems of IEEE standard, advanced TV, sound telecom and 4G portable correspondences. The principle advantage of OFDM over single-bearer plans is its capacity to manage many channels conditions without complex evening out channels. It has enhanced the nature of long-separation correspondence. The primary disadvantages of OFDM are its high crest to normal power proportion and its affectability to stage clamor and recurrence balance. This review gives a diagram of OFDM, its applications in different frameworks, for example, IEEE 802.11a, Digital Audio Broadcasting (DAB) and Digital Broadcast Services to Handheld Devices (DVB-H) along with its advantages and disadvantages
