| Abstract(in English) | This paper proposes a waveform loading type transmission technique using dynamic spectrum allocation for cognitive wireless networks. In cognitive wireless networks, because the secondary licensed bands are shared by all the wireless nodes, the usable frequency for each user would be a collection of spectrum spots rather than a continuous spectrum and its position is temporarily and dynamically changing. Therefore, in the proposed scheme, by generating fictitious line spectrum of the transmitted signal using a cyclic prefix (CP) in transmit signal, we can dynamically map line spectrum on the frequency domain and decompose and transmit a piece of spectrum via an arbitrary available band. The results confirm that the proposed waveform-loading type transmission technique is effective in dynamical and efficient utilization of distributed spot-wise frequency bands for broadband cognitive wireless systems. |
