摘要:
针对认知无线电自组网节点具有移动性及交互性的新特点,首先提出一种根据SU节点之间的空间差距赋予每个SU节点不同的权重系数,将检测结果加权平均得到共同检测结果的合作式频谱感知模型; 然后,对系统模型下授权信号可能受到的干扰进行分析,并建立多约束条件下的能量效率最优化问题的数学模型。接着,提出一种基于NLMS的干扰概率分配算法,解决在多约束条件下的能量效率最优化问题; 最后,通过实验验证感知模型及分配算法的效率。
Abstract:
Based on the new characteristics of mobility and interactivity of cognitive radio ad-hoc networks nodes, a cooperative spectrum sensing model was firstly proposed, in which, the weight coefficient was assigned to each SU node according to the spatial differences between SU nodes and the test results were weighted on average; Secondly, the possible interference of the authorized signal under the system model was analyzed, and the mathematical model of energy efficiency optimization with multi-constraints was established; Then, a NLMS based algorithm of interference probability was put forward to solve the energy efficiency optimization problem under multi-constraint conditions; Finally, the efficiency of the sensing model and allocation algorithm was verified through experiments.
