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.

Dynamic spectrum access (DSA) based spectrum sharing is an effective technique to alleviate the shortage of radio spectrum supply. Most of the existing schemes are only for simple heterogeneous cognitive radio networks. In this paper, we propose a distributed dynamic spectrum access scheme for complex heterogeneous cognitive radio networks. Simulation results show that the algorithm can significantly improve spectrum utilization while controlling the interference of SU to PU. This report consists of the following four parts, which are introduction, model, simulation results and conclusion.
