چکیده
In this work, Orthogonal Frequency Division Multiplexing’s (OFDM) principles, implementation design or high-level system architecture and application were reviewed. The condition for orthogonality, frequency spacing between consecutive subcarriers (called spacing) was established analytically with practical instance highlighted. review also covers Fast Fourier Transform (FFT) which serves as a bank of demodulators while Inverse (IFFT) modulators in an OFDM system, advancement OFDM, Quadrature modulation types (Binary Phase Shift Keying, 4-Quadrature Amplitude Modulation, 8-Quadrature 16-Quadrature 64-Quadrature Modulation QAM) spectrum efficiency covered. Several technologies that use mentioned but attention given to its usage Wireless LAN 802.11a.

Orthogonal Frequency Division Multiplexing: An Overview
Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier modulation scheme that provides efficient bandwidth utilization and robustness against time dispersive channels. This paper deals with the basic system model for OFDM based systems and with self-interference, or the corruption of desired signal by itself in OFDM systems. A simple transceiver based on OFDM modulation is present...
