| Abstract: | This paper presents an in-depth analysis of the interference strength and required guardband width between coexistent users for distributed orthogonal frequency division multiple access (OFDMA).In dynamic spectrum access networks,the cross-band interference between spectrally adjacent users is considered harmful with frequency guardbands inserted between spectrum blocks to eliminate the interference.However,the strength of the cross-band interference depends heavily on the user heterogeneity in different OF... |
