    New chaos-particle swarm optimization algorithm by Xiao-bo XU, Kang-feng ZHENG, Dan LI, Bin WU, Yi-xian YANG

    Published 2012-01-01
    “…The original particle swarm optimization (PSO)algorithm has the advantages of fast convergence,but with the shortcoming of premature and local convergence.To overcome this problem,a new chaos-particle swarm optimization algorithm was presented,which was different from the conventional method of replacing pre-particle.Instead,the algorithm in this paper made the motion of particles with characteristics of chaos,so as to make particles move between the state of chaos and stable,and gradually close to the optimal value.The nonlinear dynamics of the proposed Mathematical model are analyzed,and the results of the experiment show that the proposed algorithm can result in encouraging results.…”

    High efficiency differential chaos shift keying modulation scheme without intra-signal interference by Hua YANG, Guo-ping JIANG, Jun-yi DUAN

    Published 2015-06-01
    “…To eliminate the adverse effect brought by the intra-signal interference components in decision variables in high efficiency differential chaos shift keying system,a novel high efficiency differential chaos shift keying modulation scheme without intra-signal interference was proposed.By changing signal format of the chaotic carriers,the proposed scheme makes the two modulated chaotic signals transmitted in same time slot strictly orthogonal,which removes all possible intra-signal interference components from all decision variables clearly.It is shown by the analysis and simulation results that the proposed system has much better performance than HE-DCSK.…”

    Security on a cryptographic model based on chaos by WEI Jun1, LIAO Xiao-feng2, YANG Ji-yun2

    Published 2008-01-01
    “…The application of chaos in cryptography has attracted much attention,however,most of them were cracked soon after publications.To find why they are so weak under the attack to their chaotic signal streams,some chaotic cryptosystems were investigated.A mathematical model was then derived from these cryptosystems.Attack and corre-sponding improvement were deployed based on the model.The research is validated with a cryptanalysis on a chaotic en-cryption scheme presented by LI S J in Physics Letters A.…”
