The influence which satellite signal anomalies have on the positioning accuracy is considered in this paper. According to the 2OS (Second-Order Step) threat model of satellite signal anomalies, i.e. TMA (Threat Model A), TMB (Threat Model B), TMC (Threat Model C), the correlation peak characteristics are analyzed and the simulation is made in the 2OS model parameters space. Then the similarities and...
On the basis of the analysis on the theories and methods of fuzzy clustering and extension group decision-making, this paper established an associated clustering model of analysis of extension group decision-making, centered on correlation function and combined fuzzy equivalence relations with extension transformation. Not only does this method take the advantages of dynamic classification in extension...
Aiming at the special space in the tunnel, this paper assumes the geometric distribution of scatterers which is totally different from on the ground, puts forward a new GBSB model of MIMO channel and deduces the space-time correlation function of the model. The results of theoretical analysis and simulation show that the model can more accurately reflect the factors which impact the channel correlation...
In this paper to further enhance the measuring precision of vibration signal in the process of rotary machine fault diagnosis, a new data fusion method is presented on the basis of correlation function to determine the weighted value. The method doesn't require knowing the prior knowledge about sensors, and the weighted value of sensors can be determined on the basis of the correlation measure of...
