Context-aware plays a key role in the wisdom network information processing. Due to limited resources, context conflict is inevitable in context-aware. User satisfaction is a good reflection for the wisdom degree of the network. In this paper, through considering the user satisfaction, we propose a novel context-aware conflict solution model based on SPA(set pair Analysis). The model obtain the best...
It is greatly significant to detect harmonic accurately and effectively for improving the quality of electric energy in the power system. Actually, much noise exists in signal besides harmonics, inter-harmonics, so the key is how to detect harmonic signals from the complex power system. According to the analysis of harmonic and noise, a new method is proposed in the paper to detect harmonic based...
This paper introduces the advantages of a new type of radar signal. This signal adopts the linear frequency modulation in the pulse modulation mode and phase coded modulation method between pulses. In this paper, we use the ambiguity function theory and LPI theory to analyses the composite radar signal. Analysis result shows the superiority of the signal.
Gradient method because of its good convergence speed and separation performance, it is an important way for blind source separation. But in order to offset the expansion factor of uncertainty, the basic natural gradient algorithm forces sources to have constant magnitude. When the source are nonstationary signals, such constraints forced rapid changes in rate of separation matrix, which will affect...
Empirical mode decomposition (EMD) is an effective signal analysis method, which can decompose the original signal into several intrinsic mode functions(IMFs). In this paper a new signal analysis method of FastICA-EMD is introduced. The method is illustrated on simulated and real data, and the results are compared to traditional EMD method. The study is limited to signals that were corrupted by additive...
DSR protocol, the on-demand routing protocol used commonly in ad hoc, is suited for the situation of low mobility and few data. DSR becomes the first choice of the designers of WSN depending on the characters of it. In order to satisfy the requirement of low energy, the paper proposes a new routing protocol named energy-related DSR. First, DSR protocol is introduced in brief, and then a way of realizing...
