Secure beamforming design for IRS-assisted SWIPT Internet of things system
Published 2021-04-01“…In order to meet the new requirements of intelligent signal processing deployment and physical layer security for green interconnection of things, a design method of secure beamforming was proposed to solve the problem of the shortage of sustainable energy supply in the information and energy transmission at the same time Internet of things (IoT) system assisted by intelligent reflecting surface (IRS).Considering the constraints of secrecy rate, transmit power and IRS reflection phase shift, the optimization problem was modeled as a non-convex quadratic programming problem with quadratic constraints, aiming at maximizing the acquisition power of energy collector, and jointly optimizing the base station transmit beamforming matrix, jammer covariance matrix and IRS phase shift.The non-convex quadratic problem was transformed into an equivalent convex problem by using the relaxation variable, semidefinite relaxation method, auxiliary variable and sequence parameter convex approximation method, and an alternative iterative optimization algorithm was proposed to obtain the feasible solution of the original problem.Simulation results show that the proposed algorithm can converge quickly and improve performance effectively compared with the benchmark scheme.…”

Evaluation method of penetrating jamming effectiveness for cognitive communication protection
Published 2023-11-01“…In order to support the implementation of “multidimensional orthogonal configured communication protection between communication modules as well as parameters and interference” in cognitive communication countermeasures scenarios, jamming effectiveness requires module level responsiveness.A penetrating jamming effectiveness evaluation method was proposed.Firstly, the core parameters of each signal processing module were selected as evaluation parameters.Secondly, analytic hierarchy process (AHP) and entropy weight method (EWM) were used to determine the weight of indicators.The coordination problem in AHP was solved through expert weight allocation, and the weight allocation problem in EWM was solved through non-uniform mapping.Finally, the subjective and objective weights were weighed through game theory, and the jamming effectiveness was judged by the technique for order preference by similarity to ideal solution (TOPSIS).By conducting evaluation experiments on the jamming performance of the Link16 data link, taking into account multiple aspects such as jamming types, number of jamming frequencies, jamming duration, and system types.Experiment results demonstrate that the penetration-based jamming performance evaluation method not only provides a more intuitive representation of the relationship between evaluation results and metric parameters, but also possesses excellent jamming discrimination capability.…”
