【摘要】 主要介绍了一种新的基于ADS(AdvancedDesignSystem)环境下的W-CDMA信号产生方法,对其中所运用的多信道传输,码分多址以及脉冲成型技术做了重点分析,并在安捷伦公司提供的ADS仿真工具上对信号的产生过程进行了仿真,特别研究了内插系数对通信系统邻道功率比的影响。结果表明系统产生的信号各项性能指标均很好地模拟了实际信号,这将有助于信号的进一步分析和测试以及对通信系统的性能进行深入研究。更多还原

【Abstract】 This paper introduces a new approach to simulating W-CDMA signals based o n ADS software environment.Some applied critical techniques,s uch as multiple channel transmissio n,CDMA and pulse -shaping,are in detail analyzed.It is also researched on how the interpolation coefficients affect commu nication systems.The simulation on the ADS software plat-form from Agilent shows that the prod uced signal reproduces the real sign al exactly.Therefore this approach can make the analy-sis and measurement of signals easie r and help to analyze the performance of communication systems comprehen sively.更多还原
