Abstract
In order to satisfy compatibility between multi-band orthogonal frequency division multiplexing (MB-OFDM) Ultra-Wideband cognitive radio systems and narrowband system, polynomial interference cancellation coding (PCC) is introduced. Simulation indicates that based on this method, the side-lobe signal of MB-OFDM decreases quickly, and then the frequency notch is deep enough. In addition, relationship between the number of sub-carrier turned off and width of frequency notch is given.
