First, introduce the background. With the development of the information society, the rapid increase in the number of wireless devices has led to a sharp increase in the demand for wireless spectrum. However, the static spectrum allocation mechanism and the scarce wireless spectrum lead to the imbalance of spectrum supply and demand. We urgently need a technology to realize spectrum sharing. Secondly, the research significance is that dynamic spectrum technology can realize the sharing of wireless spectrum, which is conducive to solving the problem of spectrum imbalance between supply and demand. |
