【摘要】 本文对UWB的两种系统模式TH-BPSK和DS-BPSK进行了时域和频域的分析,可以看到它们的功率谱中都存在着离散谱线。通过仿真分析表明,由于离散谱线导致了UWB功率谱的不平坦,使得UWB对不同中心频点的GSM信号的抗干扰能力差别很大,适当地对UWB所传输的数据和扩频码进行编码和优化可以提高UWB对GSM的抗干扰性能。另外,这种方法对分析其它窄带系统对UWB系统的干扰有着借鉴作用。更多还原

【Abstract】 In this paper,two system models of UWB-TH-BPSK and DS-BPSK are analyzed both in time domain and in frequency domain.It is observed by theoretical analysis that there exist discrete spectral lines in the PSD of UWB which lead to the unevenness of PSD.The simulations display that the performance of UWB varies greatly in the presence of GSM with difference center frequency and proper encoding and optimization of the data and spead-spectrum code can improve the performance of UWB against GSM.in addition,this method can be used in the analysis of other narrowband system interference on UWB.更多还原
