【Abstract】 This paper introduces a new approach to simulate W-CDMA signals based on ADS software environment. Some applied critical techniques, such as multiple channel transmission, CDMA and pulse-shaping, are in detail analyzed. It is also researched on how the interpolation coefficients affect communication systems. The simulation on the ADS software platform from Agilent shows that the produced signal reproduces the real signal exactly. There fore this approach can make the analysis and measurement of signals easier and help to analyze the performance of communication systems comprehensively.更多还原
