| Research Abstract |
In this work, we have investigated dynamic spectrum sharing with four resource dimensions based on cognitive radio technique. The aim of this study is to solve spectrum scarcity problem in wireless communication field. We have investigated channel occupancy rate information based spectrum sharing technique, MIMO-based space domain spectrum sharing, and frequency hopping, for the dynamic spectrum sharing. This work has shown that the above techniques can enhance the efficient spectrum usage significantly.
