This method aims at identifying unlabeled ships in high-resolution, based on the theory of transfer learning, assisting with a number of ship samples with different resolutions from different satellites. In the traditional machine learning method, training data and test data are assumed to have the same distribution. However, because of the different distributions and spaces in most cases, such as images from different satellites, the accuracy rate will decline. In this paper, we proposed a method that aligns the distributions as well as the subspace bases to solve this problem. This paper first proposed Adaptation Local Linear Embedding (ALLE) algorithm to achieve space alignment and then aligned both marginal distribution and conditional distribution by Joint Distribution Adaptation (JDA). This paper focuses on the identification of three types of ships which are destroyers, cruisers, and aircraft carriers basing on the method proposed (ALLE-JDA), using the knowledge of source samples low-resolution labeled ships to help identify the unlabeled high-resolution samples. The experimental results show that this method is better than several state-of-the-art methods.","PeriodicalId":201746,"journal":{"name":"2018 IEEE/CIC International Conference on Communications in China (ICCC Workshops)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114663853","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}

In the proposed cellular networks, the base station (BS) would like to communicate multiple users via multiple relays, while that the direct link between BS and users are not considered. Specifically, we further assume that of two relays in approaching scopes to the user can assist the transmission, since that other relays are out of the cooperation scopes. By this way, each user and two corresponding relays can be implemented as one group. In addition, the source simultaneously transmits the superposition coded signals to the relay nodes. After receptions, multi-relay nodes decode the symbols by applying the successive interference cancellation (SIC), and then reconstruct them into new NOMA signals, which will be forwarded to the receiving nodes. The users jointly decode the information symbols received from two adjacent relay nodes with a practical and simple operation, also derive the closed-form expressions of the sum-rate (SR). Qualitative numerical results corroborating our theoretical analysis show that the proposed scheme significantly improves the SR performance compared with the existing works.","PeriodicalId":201746,"journal":{"name":"2018 IEEE/CIC International Conference on Communications in China (ICCC Workshops)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125955036","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, they were unable to completely remove the cell-boundary effect and led to increased complexity and overhead. In order to realize the gain of user virtualization, this paper proposes a tractable virtual user equipment (UE) forming procedure in which a set of qualified UEs is selected to serve as small cells. Specifically, the UE group completes discovery and connection among each other in a self-organized manner, and the donor femto transmission point (FTP) manages the data transmission and handover of the virtual UE group cooperatively. Meanwhile, the context information from both users and networks is utilized to locally optimize the composition of the virtual UE group, which adapts to each user’s environment and quality of service (QoS) requirements. Simulation results illustrate that the virtual UE design achieves an increase of maximum 65% for success probability under high spectral efficiency request compared to the LTE system and efficiently improves average user throughput.","PeriodicalId":201746,"journal":{"name":"2018 IEEE/CIC International Conference on Communications in China (ICCC Workshops)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117150305","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}

To make good use of such a nature to fully exploit the advantages of NOMA, in this paper, we study the outage performance enhancing scheme for the downlink cooperative NOMA systems, where two users communicate with the base station with the assist of a single relay. Assuming Nakagami-m fading channels and the regenerative protocol is applied to the relay, system’s ergodic sum rate and users’ outage probability are derived in closed form. Numerical results verify the accuracy of the theoretical analyses and demonstrate that with the diversity enhancing strategy, the proposed NOMA scheme outperforms the conventional NOMA and time division multiple access (TDMA) schemes in terms of outage probability greatly. Moreover, it shows that the proposed NOMA scheme can almost achieve the same ergodic sum rate as the conventional NOMA scheme has in the high SNR region.","PeriodicalId":201746,"journal":{"name":"2018 IEEE/CIC International Conference on Communications in China (ICCC Workshops)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115148479","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}
