Abstract(in English) | For an efficient spectrum sharing by primary user (PU) and secondary user (SU), SU needs to understand the spectrum usage by PU properly. Specifically, it has been reported that statistical information of spectrum usage by PU can enhance the efficiency of the spectrum sharing. In this paper, we focus on the duty cycle (DC) as statistical information of spectrum usage by PU, and we investigate a time-series modeling of DC, such as AR (Auto-Regressive) model. In a general AR model, the time fluctuation of statistics are not considered. In addition, the experimental results verifies that there are two types of periods: high correlation time period and low correlation time period. We propose a model in which the two types of periods and the time fluctuation of statistics. In the proposed time-series model, we employ detection method of the two states (high correlation state and low correlation state). Two different types of time-series models are used for the two sates. We show the validity of proposed model by experiment of spectrum measurement in 2.4 GHz band. |
