A Study on the Effect of UWB Interference on Downlink UMTS System


In this paper, we evaluate the performance of UMTS(Universal Mobile Telecommunication System) downlink system invicinity of UWB system. The study is achieved via simulating ascenario of a building which is located within UMTS cell bordersand utilizes from both UMTS and UWB appliances. Thesimulation results show that the UMTS system is considerablyaffected by the UWB interference. However, in order to battle thisinterference and achieve reasonable BER (Bit Error Rate) of 10-4,we found that it is very necessary to carefully raise the UMTS basestation transmitted power against that of UWB interferer. So, theminimum requirements for UMTS system to overcome UWBinterference are stated in this work
