Abstract


WiMax is an emerging broadband wireless access technology , can provide high-speed Internet connection . QoS guarantee , high transfer rate , business rich and diverse . WiMax technology from a higher mobility OFDM / OFDMA represent the future direction of the development of communication technology , AAS, MIMO and other advanced technology , with the development of technical standards , WiMax will gradually achieve broadband services . Because of its high coverage in the field of data communication ( covering the range of 25 to 30 miles ) , and 3G may constitute a threat to make WiMax industry has been concerned . UWB technology has a strong anti-interference performance , high transfer rate , a very wide bandwidth , consume energy , transmit power and other technical advantages , the most concern in the short - distance wireless communication technology . Therefore , mutual interference of the two existing communication system based on the importance of the above two types of communication system , as well as the possibility of coexistence is particularly important. Today UWB system and many narrowband systems such as UMTS, GSM, GPS coexistence in the literature and is widely discussed , but not too UWB interference WiMax system . This paper begins with a theoretical perspective influenced by the interference caused by the possibility of interference receiver UWB systems transmit power and noise figure of parameter changes on WiMax . After using Matlab tool to create simulation models , and ideology derived using the Monte Carlo method , the transmit power of UWB systems and WiMax receiver by the correspondence between the probability of interference . The simulation results are analyzed .
