| Abstract(in English) | Spectrum sharing techniques using an overlay transmission, which allow multiple radio systems to share the same time and the same frequency band, have been studied to maximize spectral efficiency. Conventional techniques using spatial signal processing separate coexisting signals in the space domain. However, timing synchronization for the overlaid system becomes a serious problem because of the interference from the primary system when sharing the same frequency. In this paper, we propose a new overlay transmission system with IEEE 802.11 wireless LAN as a primary system, which can easily achieve timing synchronization by utilizing the information of the primary system, and evaluate it by computer simulation. |
