A Novel Code-Aided Non-Orthogonal Multiple Access Technique in Downlink MIMO System 下行MIMO系统中一种新的码辅助非正交多址技术

Conventional downlink non-orthogonal multiple access (NOMA) exploits the power domain for multiple access and applies successive interference cancellation (SIC) to mitigate intra-cluster interference. It requires sophisticated user terminals (UTs) clustering, moreover, imperfect SIC results in error propagation that severely degrades system performance. In this paper, a novel code-aided multiuser multiple-input multiple-output NOMA (MIMO-NOMA) framework for downlink transmission is developed. We propose a simple grouping algorithm that separate all UTs in a cell into several clusters, with cluster number less than or equal to the BS antenna array size. ZF-based multiuser beamforming is then employed to remove the inter-cluster interference. Computer simulation results verify that the proposed method outperforms the conventional schemes.
传统的下行链路非正交多址(NOMA)利用功率域实现多址,并采用连续干扰抵消(SIC)来减轻簇内干扰。它需要复杂的用户终端(ut)集群,而且不完善的SIC会导致错误传播,严重降低系统性能。本文提出了一种新的编码辅助多用户多输入多输出NOMA (MIMO-NOMA)下行传输框架。我们提出了一种简单的分组算法,将单元中的所有ut分成几个簇,簇数小于或等于BS天线阵列的大小。然后采用基于zf的多用户波束形成来消除簇间干扰。计算机仿真结果验证了该方法优于传统方案。

Spiking neural networks (SNNs) are artificial neural network models that are closely mimic natural neural networks. LIF (Leaky Integrate-and-fire) neuron model, population coding and Tempotron supervised learning rules are used to construct a spiking neural network for visual color feature classification based on RGB-HSV (Red, Green, Blue -Hue, Saturation, Value) model. The product of a momentum learning rate and the last weight change is proposed to speed up the training of the SNN. Test results based on a common data set show that the accuracy of the SNN can be up to 90%.

In order to improve the accurate recognition rate and localization rate of multi-class object detection, a new network structure, Res-YOLO-R., based on the combination of Residual Network (ResNet) and You Only Look Once (YOLO) detection network, is proposed. To improve the location ability and speed up the convergence of the network, the number and size of prediction boxes for YOLO network are redesigned by clustering analysis algorithm. Removing part of the pool layer and using convolution layer to raise or reduce the dimension of the feature to improve the ability of feature extraction and computing of the network. ResNet is designed as the feature extraction part, and the final average pool layer and the full connection layer are removed, and combines with the improved YOLO detection network to improve the degradation problem caused by the increasement of the network depth. In order to make the network learn object context information better, the ROUTE and REORG layers are used to fuse feature from different layers, and the feature map is reorganized. Through the comparison of experiments on commodity data sets, the network structure can effectively reduce the false detection rate and miss detection rate, improve the detection accuracy, positioning ability and recall rate of commodities, and have good real-time and generalization ability and strong practicability.
为了提高多类目标检测的准确识别率和定位率,提出了一种新的网络结构Res-YOLO-R。提出了一种基于残余网络(ResNet)和You Only Look Once (YOLO)检测网络相结合的检测网络。为了提高网络的定位能力,加快网络的收敛速度,利用聚类分析算法重新设计了YOLO网络预测盒的数量和大小。去除部分池层,利用卷积层提高或降低特征维数,提高网络的特征提取和计算能力。设计了ResNet作为特征提取部分,去除最终的平均池层和全连接层,结合改进的YOLO检测网络,改善了网络深度增加带来的退化问题。为了使网络更好地学习对象上下文信息,利用ROUTE层和REORG层融合不同层的特征,对特征映射进行重组。通过对商品数据集的实验对比,该网络结构能够有效降低误检率和漏检率,提高商品的检测精度、定位能力和召回率,具有良好的实时性和泛化能力,实用性强。

Network on Chip (NoC) that integrates a large number of nodes in a chip is a competitive candidate to solve the problems of multi-core chip scalability and clock synchronization. Among the many factors that determine the NoC’s performance, the routing algorithms that determine a path from a source node to destination node have a tremendous impact on it. Suitable routing method can greatly improve the performance of NoC. In this paper, we analyze the effect of routing algorithms commonly used in a mesh structure. We compared the data transmission in terms of latency and throughput. Furthermore, we compare which method yielded relatively good results in case of existing a failed node in the network. All results and analysis in the text are derived by using the Booksim simulator. This research proposes the direction of NoC routing algorithms.

In this paper, we proposed a wind speed and direction sensor which based on fiber Bragg grating (FBG). A broadband light source (BBS) was used as the light source. The anemometer consists of two sizes of stainless steel pipe and the coil spring designed to connect a cross-steel frame and the wind-pressed plate. When the wind speed drives the wind-pressed plate, the FBG will change the grating pitch through a special internal structure design to achieve the wind speed and wind direction sensing.

Data mining means to find valuable information in database or data sets. For imbalanced data, there are extremely low number of samples in database or data sets and it is not easy to solve these problems by traditional methods of data mining. In this paper, a distributed intelligent algorithm is proposed to imbalanced data. Apache Spark is implemented as the distributed framework in the proposed distributed intelligent algorithm, and its cluster computing framework with in-memory data processing engine can do analytic on large volumes of data. In the distributed framework, Apache Spark with synthetic minority oversampling technique (SMOTE) is proposed to process imbalanced data first. Thereafter, the support vector machine (SVM) is used to classify imbalanced data. The zoo data set from UCI repository is used to verify the correctness of the proposed algorithm. The results of the proposed distributed intelligent algorithm can get better performance than these compared traditional classifiers.

In the distributed framework, Apache Spark with synthetic minority oversampling technique (SMOTE) is proposed to process imbalanced data first. Thereafter, the support vector machine (SVM) is used to classify imbalanced data. The zoo data set from UCI repository is used to verify the correctness of the proposed algorithm. The results of the proposed distributed intelligent algorithm can get better performance than these compared traditional classifiers.","PeriodicalId":206741,"journal":{"name":"2019 IEEE International Conference of Intelligent Applied Systems on Engineering (ICIASE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131046790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
