    Novel opportunistic cooperative multicast scheme for NOMA by Yin LU, Jirong CHEN, Haowei BIAN, Hongbo ZHU

    Published 2020-11-01
    “…The cognitive radio technology was applied to non-orthogonal multiple access (NOMA) cooperative multicast system,the feasibility of using users as relays was studied,and a two-level cooperative transmission scheme with parameterized multicast candidate sets was proposed.Specifically,the scheme first selected the candidate set according to the cardinality q,and then selected the best forwarding node based on the channel gain between the primary users and the candidate secondary users.Simulation results show that,through the reasonable selection of the cardinality q,the proposed scheme can greatly reduce the diversity gain of the secondary users while simultaneously increasing the diversity gain of the primary users.In NOMA cooperative multicast scenario composed of N multicast users,the proposed scheme can increase the diversity gain of the primary users from 2 to min(N-q+2,q+1) to meet their reliability requirements.…”

    Runoff Prediction Based on VMD-LSTM-ARMA Model by LUO Cankun, LIU Hao, HUANG Xin, SHAO Zhuang

    Published 2023-01-01
    “…To increase the accuracy of runoff prediction,a combined prediction model is proposed to solve the problems of runoff prediction.This model consists of the variational mode decomposition (VMD),long and short-term memory (LSTM) network,and autoregressive moving average (ARMA).To reduce the complexity of the incoming traffic,the runoff data is decomposed into three modal components with different frequencies by VMD.The low-frequency modal component inherits the temporal properties of the data and can be processed by constructing the LSTM prediction model,while the two high-frequency sequences are stationary time series and can be processed by constructing the ARMA prediction model.The prediction results of the three subsequences are superimposed to predict the runoff.Finally,the hourly flow data of Dongjiang Hydrometric Station of Xiangjiang river tributary in 2020 are used to forecast the inflow flow,and the results of comparative experiments with other algorithms show that the constructed model can effectively improve the accuracy of the hydrological forecast.…”
