中文摘要：
动态频谱共享技术允许认知用户接入未授权的频谱,可以有效地提高频谱资源的利用率.针对图论着色算法中产生的单轮分配聚集现象,提出了基于协作式最大化频谱总效用和协作式最大化比例公平的联合准则算法.该算法在计算节点间的着色标号时采用不同的准则,进而提高了用户间分配的公平性,同时降低了时间开销.
英文摘要：
The dynamic spectrum access technology can achieve near-optimal spectrum utilization by allowing cognitive users to sense and utilize available spectrum opportunistically.Aiming at the ＂phenomena of once-assignment aggregation＂ of the graph coloring algorithms,a novel joint rules algorithm based on the collaborative max sum bandwidth rule and collaborative max proportional fair rule is proposed.The algorithm uses two different rules when calculating the node label,through which the allocation fairness between the cognitive users is improved,and the time overhead is reduced at the same time.Simulation results verify the feasibility and validity of the proposed algorithm.
