    Channel estimation of UFMC system in multipath channel by Xiang YU, Yanni GAO, Sirui DUAN

    Published 2018-04-01
    “…As a candidate waveform of 5G,universal filter multi-carrier (UFMC) technology could inhibit out-of-band radiation,achieve loose synchronization and well support the short bursts of things in the transmission.However,in the UFMC transmission without cyclic prefix (CP),inter-symbol interference (ISI) and subcarrier interference (ICI) are generated in the multipath fading channel,which will affect the estimation accuracy in channel estimation.The interference of the UFMC system in multipath channel was firstly analyzed.After using the feedback equalization suppression ISI,the self-elimination algorithm was used to suppress the ICI according to the similarity between adjacent carriers,and the pilot coefficients were designed according to the UFMC system.Finally,the simulation results show that the proposed method applied to the UFMC can suppress the interference,improve the accuracy and reduce the bit error rate.…”

    Entanglement microscopy and tomography in many-body systems by Ting-Tung Wang, Menghan Song, Liuke Lyu, William Witczak-Krempa, Zi Yang Meng

    Published 2025-01-01
    “…Abstract Quantum entanglement uncovers the essential principles of quantum matter, yet determining its structure in realistic many-body systems poses significant challenges. Here, we employ a protocol, dubbed entanglement microscopy, to reveal the multipartite entanglement encoded in the full reduced density matrix of the microscopic subregion in spin and fermionic many-body systems. …”

    Model of fuzzy risk assessment of the information system by ZHAO Dong-mei1, MA Jian-feng1, WANG Yue-sheng2

    Published 2007-01-01
    “…A model of risk assessment was introduced to the estimation of the information system.The method,which combined AHP and fuzzy logical method,was applied to the risk assessment.AHP and fuzzy logical method were altered according to the actual condition of the risk assessment of information system.Applying fuzzy logical method,the im-portant degree of each factor was judged in the aspects of the probability,the impact severity and uncontrollability,not judged immediately.Finally,the risk value of each factor was calculated.By comparing the risk value of each factor,it is known that which risk can take measures to control.By introducing entropy,the proportion of each risk factor in the whole risk assessment system was calculated.Next the risk degree of the whole system was calculated.Then the risk level of the whole system can be determined.The study of the case shows that the model can be easily used to the risk assessment of the information system security.The results are in accord with the reality.…”
