摘要
Abstract
In order to analyze the influence of the parameters of the fusion matrix and the step size on the a-daptive diffusion algorithm in distributed cooperative spectrum sensing cognitive radio networks ( CRNs ) , the error performance of the estimator is studied. The general expression of the adaptive diffusion algorithm is given. The error formula of the measurement is deduced and the transient network mean square deviation ( MSD) and steady state MSD of each node are used as the standard to measure the performance of the al-gorithm. The results show that the different fusion matrix selection rules can influence the detection per-formance of the diffusion algorithm and the algorithm parameters can be studied by using the error estima-tion of statistics.关键词
