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.
