Use of Windowing Techniques on 3G CDMA Signal

Here is an example of how windowing (blackman in this example) can help reduce sidebands. This technique is useful in making spectral measurements such as Adjacent Channel Leakage Ratio. By minimizing the sidebands generated by an arbitrary waveform generator, for example, the true device performance can be more accurately measured. For more information on windowing, see the following article from National Instruments: http://zone.ni.com/devzone/cda/tut/p/id/4844
