An Orthogonal Frequency Division Multiplexing
(OFDM) system is a multi-carrier system which
utilizes a parallel processing technique allowing the
simultaneous transmission of data on many closely
spaced, orthogonal sub-carriers. Inverse Fast Fourier
Transform (IFFT) and Fast Fourier transform (FFT)
in a conventional OFDM system are used to
multiplex the signals together and decode the signal
at the receiver respectively.
This paper investigates performance of
Discrete Fourier Transform based Orthogonal
Frequency Division Multiplexing (DFT-OFDM).
