Secure performance analysis of WCDMA systems over correlated Nakagami fading channels
Published 2018-10-01“…In order to evaluate the security performance of wideband code division multiple access (WCDMA) over multiple-input and multiple-output fading channels,a time-saving and efficient solution is theoretical analysis.The exact analytical expressions of the non-zero security capacity probability and the security outage probability of WCDMA systems using space-time block codes and 2D Rake receivers (2D-Rake) on the relevant Nakagami fading channels was deduced.Using the above expressions,the effects of parameters such as the number of transmit and receive antennas,antenna correlation coefficient,Nakagami fading coefficient,and average path attenuation coefficient on the security performance of the WCDMA system could be quickly evaluated.The numerical calculation was in good agreement with the simulation results,which proved the correctness of the above theoretical analysis.The analytical expression of the asymptotic safety outage probability of WCDMA system was deduced.The results show that the security diversity gain of WCDMA system is the sum of the diversity gains on the separable paths of the main channel,and has nothing to do with the eavesdropping channel; the same for the constant multipath intensity profile The Nakagami fading channel is distributed,and the security diversity gain of the WCDMA system is the product of the number of received and transmitted antennas of the primary channel,the number of multipaths,and the Nakagami fading coefficient.…”

Multi-scale outlier mining algorithm for stateless communication data under IPv6 remote monitoring network
Published 2023-08-01“…In order to accurately mine outliers and reduce the impact of outliers on communication data, a multi-scale outlier mining algorithm for stateless communication data in IPv6 remote monitoring network was investigated.The stateless communication data were obtained through an IPv6 remote monitoring network, and based on the seasonality, trend, and self-similarity characteristics of the extracted stateless communication data, the Fourier transform was used to divide the stateless communication data into two classes.Then, the K-mean method was used to cluster the two classes to determine the neighborhood of the stateless communication data, which was used as the basis for outlier mining using a convolutional neural network on the stateless communication data.The convolutional neural network was initialized, and according to the output value of the convolutional neural network, it was determined whether the network met the stopping condition.The operation steps of the convolutional neural network were repeated, all the outlier points were mined, and the multi-scale outlier mining of stateless communication data was achieved.The experimental results showed that the fewer the number of stateless communication data categories, the higher the mining efficiency; the proposed method can accurately mine the number of multiscale outliers of stateless communication data in IPv6 remote monitoring network and accurately analyze the reasons for the outliers.…”
