Abstract(in English) Recently, due to the increase of huge number of wireless devices such as smartphones or sensors, mobile wireless traffic is dramatically expanding each year. Therefore, how to improve spectrum efficiency (SE) for cognitive wireless system is important and urgent research topic. Till now, there are many researches considering the prediction of Channel Occupancy Ratio (COR: the ration between busy duration length to resolution period $T$). If the start and end points of Busy and Idle duration can be correctly predicted, it will largely benefit the wireless system design and SE improvement. In this paper, we will consider such research based on autoregressive (AR) and autoregressive integrated (ARI) models using traffic data captured from the wireless channel in real environment. The major idea is that the Busy and Idle duration length can be calculated from COR value when the resolution period $T$ is short. In this paper, we first investigate the COR prediction performance using AR and ARI predictors with different value of $T$. Then using relationship between the Busy and Idle duration length and COR value, the Busy and Idle duration length prediction can be realized. From the results, we can confirm our proposal has better prediction accuracy than that of AR/ARI predictor using only Busy and Idle duration traffic data.
