Summary:
In case where external sensor detects primary signal in place of secondary devices, it is required to detect the primary signal under superposed secondary signal without time synchronization. In order to solve this problem, we had proposed primary user detection utilized by periodic structure of secondary communication without high complexity. It is necessary to detect start and end points of each frame from data measured over several periods in proposed method, however this detecting performance is decrease under the non-static traffic of secondary user. Accordingly, this paper proposes modified primary user detection under superposed TD-LTE signal, and shows improving performance under the non-static traffic of secondary user through computer simulation.
