An Application Research on Adding Windows Technology in NC-OFDM Systems

This paper discusses the inherent mechanism of adding windows technology and its application in NC-OFDM systems,for two windows and different roll-off factors,the simulation is conducted to compare the performance of the power spectrum out-of-band attenuation of the NC-OFDM signals.The results indicate that the attenuation is improved due to the added windows;meanwhile,the signals out-of-band attenuation is also different because of various windows and roll-off factors.
