| Abstract(in English) | This paper explains a spectrum loading type dynamic spectrum control technique based on cognitive radio to enhance guaranteed probability for user's quality of services (QoS). In the proposed scheme, based on the detection of available, spot-wise spectra, discrete spectrum components of the framed signal sequence are mapped on the spot-wise spectra. Computer simulation confirms that the proposed dynamic spectrum control is effective in mitigation of co-channel interference and inter-symbol interference due to its dynamic range suppression effects in the channel transfer function. This paper also shows the concept and performances of partial spectrum retransmission type ARQ as an application of the proposed dynamic spectrum control techniques. |
