Abstract(in English) | In dynamic spectrum sharing, it is useful to exploit statistical information on spectrum usage. In this paper, we investigate an AR (Auto-Regressive) modeling to predict DC (Duty Cycle) which is spectrum occupancy rate over time axis. Real DC measurements show behavior that is hard for the typical AR model to express such as a time-varying characteristic of mean DC and existence of time period with low-correlation. To overcome the behavior, we propose a DC model based on AR model considering these behavior. Specifically, the proposed model classifies the states of DC value (high or low) exploiting thresholding process and models the DC based on AR model each state. We also consider the time-varying characteristic of mean DC by means of estimation of mean DC by sliding window process. Several verifications based on real DC measurements show the proposed model can attain high enough prediction accuracy in case of long enough observation period of DC. |
