Joint time–frequency sparse estimation of large-scale network traffic

Network Information Security Situation Assessment Based on Bayesian Network

“…Network space defense forces have very limited information before the attack and the initial state of the threat level is high, medium and low probability distribution (0.4,0.3,0.4), which is consistent with the actual conditions, reflecting the uncertainty of the decision maker. After the model is initialized to wait state, once the update of the situation information input network nodes, the network inference algorithm to update the status of each network node [11], and finally get the probability distribution of node state.…”

Design of Antenna with Low Intensity RFID Wireless Network Signal

“…Hill.D.A theory deduces plane wave integral equation expression of field distribution in reverberation chamber after intensive mixing, statistical property of it can be described with plane angle spectrum of random variable [7], a certain number of random plane wave superposition is used by Franco Moglie to simulate electromagnetic wave spreading in different directions due to rotation of stirrer [3]. This article uses multi-column plane wave incident to simply simulate filed distribution in reverberation chamber and unit plane wave of direction angle and height angle which impose linear polarization as 10° interval as shown in figure 7.…”

Reconstruction of Wideband Radar Signal Based on Compressed Sensing

“…Therein, the research is mainly focused on the following two aspects: chaotic phase-coded signal and chaotic frequency-modulated signal. In the application of the chaotic sequence for frequency modulation, only the sequence generated by Bernoulli mapping can be adopted to obtain ideal autocorrelation characteristic [13]. Therefore, the chaotic sequence generated by Bernoulli mapping is adopted in this article, and Formula (7) is adopted to generate Bernoulli sequence.…”
