Abstract
In this paper, we construct two measurement systems for specifying the channel occupancy ratio. Channel occupancy ratio is useful for cognitive radio because it is estimation for finding the vacant channel. We consider two type of channel occupancy. In the average channel occupancy, we detect the signal from low frequency (LF) to Ultra High Frequency (UHF) for long terms. As a result, the average channel occupancy for each frequency channel is specified. In addition, we estimate the instantaneous channel occupancy by real time spectrum analyzer. We also construct the combining system between measurement and simulation and thus various signal detectors are available for the constructed system. From the measurement result, we analyze the MAC level channel accessing from the detected result in some cases.
