Abstract: Orthogonal Frequency Division Multiplexing (OFDM) is a special case of multi carrier modulation which represents a powerful technology with a promising future in next generation wireless communication systems. OFDM signaling has been adopted for use in digital audio broadcasting (DAB) and terrestrial digital video broadcasting (DVB-T) systems, as well as in wireless local area network (W-LAN) standard, such as the IEEE 802.11 a, IEEE 802.11 g, and Hiperlan II. OFDM has also been proposed for packet data systems. The OFDM properties will be studied. The main contribution of this work is at the level of implementation using a Matlab simulation of the transmission and reception of a signal consisting of binary data, as well as mapping and demapping block data using 16 QAM OFDM systems.
Keywords: OFDM, cyclic prefix, orthogonality, QAM
