Abstract

Abstract:

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,and achieve coexistence of systems.

Key words: MB-OFDM-UWB, WiMAX, DAA, interference
