A Study of Orthogonal Frequency Division Multiplexing

Exploring the Features and Applications of Orthogonal Frequency Division Multiplexing

Abstract

The multi-carrier modulation system known as Orthogonal Frequency Division Multiplexing(OFDM) makes effective use of available bandwidth and is resistant to the effects of time-dispersedchannels. This article discusses self-interference or the corruption of the intended signal by itself inOFDM systems, and the fundamental system model for OFDM-based systems. Basically a study mainlydiscussed about Historical Perspectives of OFDM, OFDM Principle, OFDM Orthogonality, Optical-OFDM,Optical-OFDM Signal Processing, OFDM basics, Block System Representation of OFDM
