    Delay-optimal spectrum decision method for cognitive network by Wu-jian SUN, Na LI, Yang LIU, Le SUN, Tao CHEN, Hao LI, Ou LI

    Published 2012-11-01
    “…Spectrum decision was investigated within the confine of spectrum management framework for cognitive radio networks.Sensing errors in PHY layer,outage probability on wireless channel and multiple interruptions of primary user were taken into consideration.Probability-based and sensing-based spectrum decision methods were proposed,which were capable of balancing traffic evenly among licensed.For the probability-based method,short-time first discipline was employed to further shorten average residual time,closed-formed expression were presented based on dynamical programing.For the sensing based method,new channel could be chosen for uncompleted transmission,which alleviated the time spent in waiting primary user.Optimal residual time was obtained by choosing the minimal value of the two methods.Furthermore,spectrum heterogeneity was taken into consideration and theoretical analysis was of general sense.Simulation results validate the approach is efficient.…”

    A Single-Valued Extended Hesitant Fuzzy Score-Based Technique for Probabilistic Hesitant Fuzzy Multiple Criteria Decision-Making by Bahram Farhadinia, Atefeh Taghavi

    Published 2021-01-01
    “…The probabilistic hesitant fuzzy set (PHFS) is a worthwhile extension of the hesitant fuzzy set (HFS) which allows people to improve their quantitative assessment with the corresponding probability. Recently, in order to address the issue of difficulty in aggregating decision makers’ opinions, a probability splitting algorithm has been developed that drives an efficient probabilistic-unification process of PHFSs. …”

    Performance analysis of RIS-assisted mixed RF/THz system by Sai LI, Liang YANG, Qimei CUI, Siyuan YU

    Published 2022-01-01
    “…To solve the problem of the short transmission distance of terahertz (THz) links, the performance of the reconfigurable intelligent surface (RIS)-assisted mixed dual-hop radio frequency (RF)/THz system was studied.An RIS was used to enhance signal strength, thereby improving the system performance.Using the fixed-gain amplify-and-forward protocol, the cumulative distribution function and probability density function of the end-to-end signal-to-noise ratio of the RF/THz link were derived.Capitalizing on the statistical characteristics, the analytical expressions of outage probability, average bit error rate, and average channel capacity of the mixed relaying system were further derived.In addition, the asymptotic analyses of the outage probability and the average bit error rate were carried out to obtain the diversity order of the mixed RF/THz system.Simulation results show that the RIS can effectively improve the performance of the mixed RF/THz system.Furthermore, the system performance is related to the channel fading, pointing errors, and propagation distance.…”

    Outage performance of SWIPT-NOMA-CR network with imperfect SIC and CSI by Zhuhua MA, Liping LUO

    Published 2023-03-01
    “…For the cognitive relay network based on simultaneous wireless information and power transfer (SWIPT) and non-orthogonal multiple access (NOMA), which is termed as SWIPT-NOMA-CR network, considering the practical situation of imperfect successive interference cancellation (SIC) and channel state information (CSI), the outage performance of secondary users was studied by using three relay transmission schemes including ideal, time switching (TS) and power splitting (PS).The analytical expressions of outage probability were derived for the secondary users, and the theoretical derivations were validated by Monte Carlo simulations.The results show that the outage performance of secondary users is impaired due to the imperfect SIC and CSI.Compared with the imperfect CSI, the imperfect SIC causes more severe loss to the outage performance of the system.Moreover, the outage probability of PS relay transmission scheme is lower than that of TS scheme.When the imperfect SIC and CSI conditions are changed, the outage probability gap with PS scheme is less than that with TS scheme, which indicates that the reliability of PS relay transmission scheme is superior to that of TS scheme.…”
