研究UWB系统和WCDMA系统的电磁兼容问题,从物理层分别搭建二者的仿真模型,考虑DS—UWB和OFDM—UWB的不同影响,以及WCDMA特有的调制方式、编码和接收结构。根据WCDMA系统的误码率要求得到UWB的功率谱密度限制值,其结果对我国频率管理部门制定UWB频谱模板具有一定的参考价值。
This paper studies the electromagnetic compatibility between UWB and WCDMA. The simulation models based on physical layer both for UWB and WCDMA have been built. Differential impact between DS - UWB and OFDM - UWB was taken into consideration in this research, as well as the specific modulation, coding, and the receiving structure of WCDMA. According to the WCDMA systems' requirements on bit error rate, the limited power spectral density of UWB was obtained. The result may have some reference value to China's development of UWB frequency spectrum template.
