摘要 针对基于退让机制(BCM)的频谱接入方案存在的不足,提出一种基于干扰最小化、需求最大化(MIMD)的动态频谱接入方案,给出相应的MIMD动态频谱接入算法(MIMD-DSA)。使感知用户(CU)通过学习以往频段的接入经验来选择候选频段,在主用户出现时通过MIMD-DSA算法切换到这些频段。仿真和分析结果表明,与BCM方案相比,该方案能进一步提高频谱利用率。 Aiming at the deficiencies in the spectrum access scheme which is on the basis of the system of concession mechanism（BCM）, this paper proposes a new dynamic one which is based on Minimizing Interference and Maximizing Demand（MIMD）, and gives out the corresponding MIMD and Dynamic Spectrum Access（MIMD-DSA） algorithm. The proposed algorithm makes the cognitive user can select candidate access spectrum through the study of former spectrum access experience, and when the primary user appears, the cognitive user will handoff to these candidate spectrums through MIMD-DSA algorithm. Simulation and analysis results show that this scheme can further improve the efficiency of spectrum compared with the BCM scheme.
