| Abstract(in English) | A Measurement-based Spectrum Database (MSD) attracts attention as highly accurate radio environment recognition. It is important to accurately recognize the radio environment for the suitable communication parameter setting. In order to recognize wireless environment of multiple channels with limited number of observation channels, interpolation of the statistical information on the frequency axis can be used. Some papers report that shadowing has high frequency correlation. In this paper, we evaluate frequency correlation of shadowing based on actual measurement on the bands of cellular systems for confirming the adaptability of the frequency correlation to wireless environment recognition. In addition, we examine the possibility of interpolation of statistical information on frequency axis using inverse distance weighting method. |
