| 摘 要： | 研究了动态频谱分配的现状，提出基于竞价模型的频谱分配算法设计应关注的三个主要问题。针对目前基于竞价的分配模型中没有保证授权用户的QoS的缺点，通过频谱质量分级和服务质量分级，设计了一个竞价频谱分配方案。在该方案中提出干扰价格的概念，并且把干扰价格作为竞价人竞标价格的重要组成部分。仿真结果表明，干扰价格能保证主用户的QoS。 |
| 关 键 词： | 频谱分级 竞价 服务质量分级 干扰价格 |

| Abstract: | This paper researched the status quo of the dynamic spectrum allocation ,and proposed three main problems on dynamic spectrum allocation algorithm based on bidding model.While the QoS of license user was not considered in existing spectrum allocation based on bidding, in order to slove this problem,designed a new scheme of spectrum allocation based on bidding by the spectrum quality classification and the quality of service grading.The scheme presented the concept of interference pricing and set it as an important component of the bidding price.Numerical result shows that the propositional interference pricing can guarantee the QoS of primary user. |
| Keywords: | spectrum grading bidding QoS grading interference pricing |
