Wireless industry has increased significantly in recent years. To date, there and there are many companies developing high-speed wireless network to provide transmission of multimedia applications. Higher data rate and reliability of systems with OFDM allows wireless networks to support high-speed applications in large areas where the propagation medium for a little radio. OFDM - signals used in wireless access technology WiMAX, wireless local area networks based on WiFi technology and will be used in is introducing the fourth generation of cellular communication. The main factor for destroying the digital channel in a broadband wireless access systems are interference from multipath reception. The solution to this problem is the use of orthogonal frequency division multiplexing technology OFDM, which is specifically designed to combat interference multipath reception.
