Abstract

Different type of transform techniques such as Discrete Hartley transform (DHT), Discrete Cosine Transform (DCT), Fast Fourier Transform (FFT) and their inverse are used for the fast computational algorithms in digital signal processing. These transforms are used to perform the modulation and demodulation operations for the OFDM system. In this paper the three transforms are describe, these transforms are used in OFDM and shows the comparison between these different schemes used in OFDM system and also the simulation results based on the BER performances.
