Optimization scheme for the SWIPT-NOMA opportunity cooperative system by Taoshen LI, Qianli NING, Zhe WANG

“…In order to improve the spectrum efficiency and performance of the simultaneous wireless information and power transfer (SWIPT) system,the non-orthogonal multiple access (NOMA) technology was introduced to construct the SWIPT-NOMA opportunistic relay system model.The fixed signal power allocation couldn’t adjust with other parameters of the system,and then affect the outage probability and resource utilization of the system.Therefore,a joint signal power and time allocation scheme was proposed to improve the system outage performance.In the proposed scheme,the expression of signal power distribution was obtained under the condition of satisfying the quality of service (QoS) rate of the node with poor channel state,and then the relation between the interruption probability and the time distribution of the system was deduced,the time allocation parameter was adjusted to affect the outage probability.The simulation results show that the constructed NOMA system has better outage performance than orthogonal multiple access (OMA) system,and the proposed joint signal power and time allocation outage scheme can effectively reduce the interruption probability of the system and improve the system performance.…”

Network traffic anomaly detection method based on multi-scale characteristic by Xueyuan DUAN, Yu FU, Kun WANG, Taotao LIU, Bin LI

“…Aiming at the problem that most of the traditional network traffic anomaly detection methods only pay attention to the fine-grained features of traffic data, and make insufficient use of multi-scale feature information, which may lead to low accuracy of anomaly detection results, a network traffic anomaly detection method based on multi-scale features was proposed.The original traffic was divided into sub-sequences with multiple observation spans by using multiple sliding windows of different scales, and the multi-level sequences of each sub-sequence were reconstructed by wavelet transform technology.Multi-level reconstructed sequences were generated by Chain SAE through feature space mapping, and a preliminary judgment of abnormality was made by the classifiers of each level according to the errors of the reconstructed sequences.The weighted voting strategy was adopted to summarize the preliminary judgment results of each level to form the final result judgment.Experimental results show that the proposed method can effectively mine the multi-scale feature information of network traffic, and the detection performance of abnormal traffic is obviously improved compared with traditional methods.…”

Research and evaluation of sparse array for massive MIMO by Mengting LOU, Jing JIN, Hanning WANG, Qixing WANG, Jiangzhou WANG

“…Massive multiple-input multiple-output (mMIMO) enables higher spectrum efficiency by deploying a large number of antenna elements.However, mMIMO will bring a substantial increase in the number of radio frequency (RF) channel, which will result in a sharp increase in cost.Therefore, it is necessary to design mMIMO with comprehensive consideration of the trade-off between the performance and the cost.Sparse array technology can approach the performance of the uniform array with less number of antenna elements by optimizing the position distribution and excitation amplitudes of the antenna elements, thereby reducing the number of RF channels and controlling the cost, and achieving a better cost-effective balance.Both link-level and system-level evaluations and analysis of sparse array based mMIMO that targets for 6G were performed under realistic simulation settings.The results show that with little performance loss, the sparse array based mMIMO can significantly reduce the number of antenna elements and the cost of base station infrastructure.…”

Analysis of a modified MIMO multi-bounced channel model for narrow street environment by Deng-hong TANG, Jie ZHOU, Gen-fu SHAO, Mei YUAN, Qian-ying FAN

“…To establish scattering models that match realistic street transmission scenarios for more efficient M2M mobile communication systems,existing models mainly focus on single-scattering and double-scattering,while for narrow urban street environment,single-scattering assumption is rather restrictive.To overcome this problem,a modified multi-bounced channel model based on EBSBM was provided,in which the concept of equivalent scattering point is assumed.The multi-bounced propagation paths are considered as an one-bounced ellipse scattering path and characteristics of the model were further analyzed.General formulations of several important parameters such as the probability density function (PDF) of the angle-of-departure(AOD),angle-of-arrival (AOA) and Doppler shift were derived,which were applied to the performance of multiple-input-multiple-output（MIMO）system employing a circular array antenna.Doppler frequency distribution was also taken into account.The results show good agreement with the previously models,which validates the rationality of proposed model.…”

Research on deep reinforcement learning based intelligent shop scheduling method by Zihui LUO, Chengling JIANG, Liang LIU, Xiaolong ZHENG, Huadong MA

“…The unprecedented prosperity of the industrial internet of things (IIoT) has opened up a new path for the traditional industrial manufacturing model.Intelligent shop scheduling is one of the key technologies to achieve the overall control and flexible production of the whole production process.It requires an effective plan with a minimum makespan to allocate multiple processes and multiple machines for production scheduling.Firstly, the shop scheduling problem was defined as a Markov decision process (MDP), and a shop scheduling model based on the pointer network was established.Secondly, the job scheduling process was regarded as a mapping from one sequence to another, and a new shop scheduling algorithm based on deep reinforcement learning (DRL) was proposed.By analyzing the convergence of the model under different parameter settings, the optimal parameters were determined.Experimental results on different scales of public data sets and actual production data sets show that the proposed DRL algorithm can obtain better performances.…”

Big data classification method of non relational distributed submission information under differentiated requirements by Lu HAN, Weiyu CHEN, Fei ZHANG, Jianfeng HE, Huaizhen SU

“…The classification method of non-relational distributed submitted information big data under the differentiated demand was studied, aiming at the problem of multi-source heterogeneous, widely distributed submitted information with more differentiated application requirements and inability to distinguish the available information.Firstly, the usability, openness and expansibility of the non-relational distributed submission information database were analyzed.The unstructured database storage TRIP was used to store non-relational distributed submission information by combining the basic requirements of field types.Then, the hashing process within the Hamming hash family was analyzed.Under the constraint of linearity level requirements, cellular automata with multiple attractors were used to optimize the system.The optimal parameters of the multiple attractor cellular automata classifier were improved through genetic algorithm, thus improving the big data classification method.Experimental results show that this method can effectively identify and classify structured data and unstructured data in non relational distributed submission information, and has high classification accuracy.…”

Resource allocation algorithm for the downlink of multi-carrier and multi-user NOMA systems by Jie YAN, Rongfang SONG

“…Non-orthogonal multiple access (NOMA) technology had received considerable attention as a candidate technology for 5G cellular systems.The resource allocation problem in multi-carrier and multi-user downlink NOMA systems were studied with the goal of optimizing system throughput.In the solution of the problem,the linear water-filling power allocation was used between subcarriers as the fractional transmit power allocation algorithm was used between the superposed users,so that system throughput could be improved.Meanwhile,the concept of time slot was adopted in the design of NOMA transmission scheme,in order to be able to schedule more users in the scenario where the number of cellcenter users and celledge users were not equal.The whole time period was divided into two time slots.On the basis of ensuring the fairness of users,different user pairing groups were implemented in different time slots so as to fully utilizing the entire resource to improve system throughput.The simulation results show that this method can transmit more bits under the same transmit power comparing with traditional non-orthogonal multiple access(NOMA) and OFDMA.…”
