摘　　要：本文研究多载波正交频分复用超宽带(multiband-OFDM-ultra wideband,MB-OFDM-UWB)系统与WiMAX(world interoperability for microwave access)系统之间的共存干扰问题。使用ADS仿真平台建立仿真模型,对两个系统之间的频率干扰特性进行仿真,同时针对UWB系统有无采用检测避让(detect and avoid,DAA)技术的情况,对各个系统的误帧率进行仿真。仿真结果表明,MB-OFDM-UWB系统与WiMAX系统间存在同频干扰,使用DAA技术可以有效地抑制或降低系统间的同频干扰影响,实现系统共存。In this paper,we study the interference and coexistence problems between the MB-OFDM-UWB system and the WiMAX system. The models of simulation are built in the ADS to simulate the characteristics of the frequency interference between the two systems. At the same time, in both with or without using DAA technology in the UWB system cases, we simulate the frame error rate of each system , and simulation results show that the co-channel interference exists between MB-OFDM-UWB system and WiMAX system, the usage of DAA technology can effectively restrain or reduce the impact of co-channel interference between systems.
