Physical layer security for SWIPT-NOMA system in presence of randomly located eavesdroppers by Yifan DING, Guangqiu LI, Hui LI

“…The combination of non-orthogonal multiple access (NOMA) and simultaneous wireless information and power transfer (SWIPT) technologies can improve spectrum efficiency of wireless system and solve the power supply problem of user nodes.However, when energy-harvesting receivers want to maliciously eavesdrop on confidential information sent by the base station, the information security transmission of SWIPT-NOMA system will be threatened.To enhance its physical layer security (PLS) performance, the PLS model of SWIPT-NOMA system with transmit antenna selection and power split strategies was proposed.When the spatial location randomly distributed energy-harvesting receivers obey the Poisson point process, the approximate expressions for the secrecy outage probability and non-zero secrecy capacity probability of SWIPT-NOMA system were derived by using the spatial Poisson probability generation function.Numerical and simulation results verify the accuracy of the expressions.The above expressions can also be used to study the influence of eavesdropper density, the distance between the base station and the far and near information receivers, the number of transmitting antennas and the power split factor on PLS performance of SWIPT-NOMA system.…”

Simulation of Soil Temperature and Humidity at Mado Station by CLM5.0 Model Encrypted Soil Layering Scheme by Yiqun BAO, Shihua LÜ, Zisha LIU

“…The source of the Yellow River is an important water conservation area in the Yellow River Basin， and it is of great significance to study the influence of different soil stratification on the simulation results of freeze-thaw process and to improve the model's simulation ability of water-heat transport process for the study of freeze-thaw process in the alpine region.In this paper， we use the observation data from Mado station in the Yellow River source area as the forcing field to drive the land surface model CLM5.0 （Community Land Model） to simulate in Mado station， and use the three improved soil layering schemes of CLM5.0 to simulate the influence of different soil layering on the soil freezing and thawing process， and compare the simulation results with the observations to analyze the influence of the improved layering schemes on the land surface model.CLM5.0 in the Yellow River source area in the process of freezing and thawing on the soil temperature and humidity simulation ability to improve the effect of the following conclusions： （1） adjusted three soil layering scheme on the simulation of soil temperature at Mardo station has a better effect of the improvement of the simulation of the three programs in the 30-layer program simulation of the best effect of the simulation， simulated values and the average correlation coefficient with the observed value reaches 0.954， the average root-mean-square error of 3.334 ℃ （2） The simulation effect of the three adjusted soil layering schemes on soil moisture at Mado station is also improved more significantly， which can accurately capture the seasonal changes of soil moisture in each layer in a whole year， affected by precipitation， the simulated values are not sufficiently relevant to the simulation of the troughs of the measured values， and the best simulation effect is achieved in the 30-layer scheme among the three schemes， with an average correlation coefficient of 0.770， and an average root-mean-square error of The average correlation coefficient is 0.770， and the average root mean square error is 0.039 m3·m-3； （3） For the simulation of the initial day of freezing and the initial day of ablation， the adjusted three different soil layers have obvious effects on the simulation of the freezing period and the ablation period， and the simulated initial day of freezing and the initial day of ablation of the shallow layer are in line with the observed values， while the simulation of the initial day of freezing and the initial day of ablation of the deeper layer is somewhat biased， with delays compared with the observed values， and the period of ablation is more persistent.…”
