Abstract:

Orthogonal Frequency Division Multiplexing (OFDM) is one of the latest modulation techniques used in order to combat the frequency-selectivity of the transmission channels, achieving high data rate without inter–symbol interference. The basic principle of OFDM is gaining a wide spread popularity within the wireless transmission community. Furthermore, OFDM is one of the main techniques proposed to be employed in 4th Generation Wireless Systems. Therefore, it is crucial to understand the concepts behind OFDM. In this paper it is given an overview of the basic principles on which this modulation scheme is based with fundamental results using 4-QAM & QPSK using AWGN, Rayleigh and rician channels. 

Keywords: OFDM, 4-QAM, QPSK, AWGN channel, Raleigh channel, Rician channel, DFT, Cooperative wireless Communication.
