In through-the-wall scenario, due to the serious attenuation of signals caused by wall, the energy of target reflection signal decreases significantly and is submerged in the direct signal of the transceiver and the reflection signal of indoor static objects, making it difficult to be extracted. Therefore, the existing WiFi sensing system has some limitations in throughthe-wall scene, especially in detection of the stationary human target and the number of moving human targets. According to the above problem, we propose a detection system TWMD based on multidimensional signal features in this paper. Firstly, the received Channel State Information (CSI) data is preprocessed to eliminate the phase error and amplitude noise. Then, the multidimensional features are fully extracted from the correlation coefficient matrix by using time correlation and subcarrier correlation of CSI. Finally, the mapping between features and detection results is established by Back Propagation (BP) neural network. Our experimental results show that the recognition accuracy of TWMD in the environment with glass wall, brick wall and concrete wall are above 0.980, 0.900, 0.850, respectively. Compared with the existing detection system based on single signal feature, it improves about 0.450 in the detection of the number of moving targets.","PeriodicalId":210825,"journal":{"name":"2019 IEEE Globecom Workshops (GC Wkshps)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115314108","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}

The key challenge is to jointly optimize the receive analog beamformer and estimate the angle of arrival (AoA) with consideration of mobile terminal (MT) rotation and environment changes over time. We propose an inertial sensor aided predictive beam tracking (PBT) scheme to exploit the attitude information available at the MT. Specifically, the AoA changes due to the local rotation which is on the time-scale order of a few 100 ms, and thus can be well predicted with prediction error modeled by an additive Gaussian random variable. Then, by taking the prediction error into account, the receive beamformer is opti- mized based on the Bayesian CramÃ©r-Rao bound. Subsequently, the maximum a posteriori (MAP) estimate is employed for AoA estimation. The resultant estimator is equivalent to achieve a balance between the pilot-based AoA estimation and sensor-aided AoA prediction. The numerical simulation results validate that the proposed low- complexity PBT scheme can accurately track the beam even for dynamic scenarios. Meanwhile, the rotation information provided by the local sensors is of critical importance for beam tracking.","PeriodicalId":210825,"journal":{"name":"2019 IEEE Globecom Workshops (GC Wkshps)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116898914","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}

There is a strong dependence between the features of the fund data and a long-term dependence between the output of different time steps, which makes it difficult to obtain good performance in the fund data in the data analysis model used in the traditional intelligent investment system. This has brought difficulties to fund correlation analysis. In order to solve the above problems, this paper uses an encoder-decoder model combined with the attention mechanism--Improved RNN model. The Encoder-decoder model has made great strides in the application of financial time series analysis. And the attention mechanism can select specific feature inputs and previous time step outputs, both of which are highly correlated with the current output, making system predictions more efficient. This paper applies this model to the historical data set containing multiple public funds. The results show that the fund intelligent investment system proposed in this paper performs best.","PeriodicalId":210825,"journal":{"name":"2019 IEEE Globecom Workshops (GC Wkshps)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127302354","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}

However, due to the long distance between the satellite and the terrestrial terminal, the coverage of the main lobe in the satellite downlink is so large that the eavesdropper can get into the coverage easily despite of using spot beams. When the eavesdropper is close to the legitimate user, the difference between the main channel and the wiretap channel is small, which makes the secrecy capacity decrease rapidly. This paper proposes a novel scheme to solve this problem by using two different beams which work on different frequencies to transmit the same signal to the legitimate user. This dual-beam dual- frequency scheme can enlarge the difference between the desired channel and the wiretap channel. Then, if we add some artificial noise set the proper beamforming vectors, the secrecy capacity will remain high when the eavesdropper is in the small zone near the legitimate user. In order to derive the artificial noise and the beamforming vectors, we transform the problem into a semidefinite problem and use CVX tools to solve the problem. Simulation results prove that this scheme can achieve high secrecy capacity even when the eavesdropper is very close to the legitimate user.","PeriodicalId":210825,"journal":{"name":"2019 IEEE Globecom Workshops (GC Wkshps)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126713238","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}

Due to its programmable nature, it is getting more popular in every research domain of Computing. Moreover, Named Data Networking (NDN) architecture is also more beneficial and emerging technology of Internet. NDN focuses on the content name instead of its location and replaces the usage of IP addresses. Lot of research has been made to integrate SDN and NDN due to their benefits of better management-ability, flexibility, less complexity, centralized control, decoupled control and data planes etc. Mobile Ad Hoc Network (MANET) is also getting more popular due to huge advancement in Mobile communication devices. Combining SDN and NDN in MANET will resolve lots of problems (i.e. forwarding, mobility, management etc.) which are difficult to tackle with single architecture. Broadcast Storm is always a challenging issue in Ad Hoc networks like MANET. In this paper, we proposed a Controller based Selective Forwarding (CSF) scheme by merging SDN, NDN and MANET to overcome the Broadcast Storm Problem (BSP) and other issues caused by BSP. CSF is evaluated using different simulation parameters which shows superiority over the Native ND-MANET in reference to BSP.","PeriodicalId":210825,"journal":{"name":"2019 IEEE Globecom Workshops (GC Wkshps)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116466381","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}
