Abstract: Grounded on the analysis of the latest bidding algorithm, contra posing to low utilization of spectrum in spectrum allocation, a bidding mechanism-based spectrum allocation algorithm of high spectrum utilization is proposed in Cognitive Radio(CR). And the interference pricing is introduced which makes the system interference reduced by setting the interference pricing index, then the quality of service of primary user is ensured. Simulation results demonstrate that the proposed algorithm is effective to improve the spectrum utilization and increase system throughput by multiple allocation.

摘要： 通过对最新竞价算法的分析，针对频谱分配过程中频谱使用率低下的缺点，提出一种认知无线电中基于竞价机制的具有较高频谱使用率的频谱分配算法。引入干扰价格，通过设置干扰价格指数，降低系统干扰，保证主用户的服务质量。数值仿真结果表明，该算法通过多次分配有效地提高了频谱的利用率，增加了系统的吞吐量。
