超宽带和GSM的电磁兼容分析
EMC Research between UWB and GSM Systems
摘要 研究了UWB系统和GSM系统的电磁兼容问题,从物理层分别搭建二者的仿真模型,介绍了DS-UWB和OFDM-UWB的不同影响,以及GSM特有的调制方式、编码和接收结构。根据GSM系统的误码率要求得到UWB的功率谱密度限制值。

Abstract To resarch the electromagnetic compatibility between UWB and GSM, the
simulation models based on physical layer both for UWB and GSM have been built.
Different impacts from DS-UWB and OFDM-UWB were taken into consideration in this
research, and the specific modulation, coding and receiver structure of GSM were also
analyzed. According to the GSM systems restriction on bit error rate (BER), the limited
power spectral density of UWB was obtained.
