In this paper, we integrate the visual 3D reconstruction with the mobility of mobile platforms to address the active visual 3D reconstruction problem in multi-agent networks. We first establish a statistical model of the visual 3D reconstruction problem in multi-agent networks. Then we propose a next-best-view selection scheme to find the best camera configuration in active reconstruction. Moreover, we propose a statistical evaluation criterion to substitute traditional laser-scanned-model-based methods to measure the reconstruction quality under certain camera configuration. Numerical results verify the effectiveness of our methods.","PeriodicalId":108635,"journal":{"name":"2019 11th International Conference on Wireless Communications and Signal Processing (WCSP)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121909271","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}

Different from existing work that employs the FD scheme with self-interference (SI) suppression, a joint time and power allocation (JoTPA) scheme is studied to minimize the outage probability by using the SER relay, which can utilize both the source signal and the SI signal to harvest energy. In particular, the outage probability of the proposed scheme is investigated with the statistical and instantaneous channel state information, respectively. For the static JoTPA, an approximate expression of outage probability is obtained to determine the optimal static time allocation (TA) and power allocation (PA) ratios. Moreover, we propose a two-step search algorithm with the dynamic JoTPA to derive the optimal dynamic TA and PA ratios for minimizing the outage probability. Finally, numerical results are provided to validate the superiority of our proposed scheme over the SI suppression scheme.","PeriodicalId":108635,"journal":{"name":"2019 11th International Conference on Wireless Communications and Signal Processing (WCSP)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122068763","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 the sparse structure of UWB channels, compressive sensing (CS) is suitable for UWB channel estimation. Capitalizing on the sparseness of random UWB channels in the basis of eigen functions, eigen-dictionary has been adopted. While the contribution of every atoms to the reconstruction of the channels is different, we develop a weighted eigen-dictionary.

In our scheme, the whole frequency resource is divided into a lot of sub-carriers which are not always orthogonal and each subcarrier is allocated to multiple users according to NOMA principle. Energy efficiency (EE) is formulated under basic data rate requirements and the maximum transmitting power constraint of base station (BS). Due to the non-convex nature of the problem, we decompose it into two sub-problems: subcarrier allocation and power allocation. Subcarrier allocation is implemented in a greedy manner based on the predefined NOMA pairing principle and power allocation is transformed into a sequence of convex sub-problems by successive convex approximations. Numerical results demonstrate the correctness of our analysis and effectiveness of our algorithm. Additionally, GFDM can be easily integrated with cognitive radio to further enhance the performance of wireless communications.","PeriodicalId":108635,"journal":{"name":"2019 11th International Conference on Wireless Communications and Signal Processing (WCSP)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121151370","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, the computational complexity of channel estimation increases exponentially with the number of antennas. Fortunately, experiments reveal that there exists two kinds of structured common sparsity properties in massive 3D MIMO channel. One is the temporal domain common sparsity property shared by antennas, the other is the angular domain common sparsity property shared by multiple users. By jointly exploiting these two properties, we propose a user grouping based structured joint sparse channel estimation (UG-SJSCE) algorithm which can achieve significantly lower complexity. The simulation results show that compared with conventional CS algorithms, our proposed UG-SJSCE algorithm can achieve lower normalized mean squared error (NMSE).","PeriodicalId":108635,"journal":{"name":"2019 11th International Conference on Wireless Communications and Signal Processing (WCSP)","volume":"32 40","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120823085","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}

Although there are many available positioning techniques, most of them are used in indoor positioning. In this paper, we discuss a possible method to locate a mobile device in massive multiple-in-multiple-out(MIMO) systems which represents a leading 5G technology candidate. In offline phase, the fingerprint matrix based on angle-delay channel power is extracted and compressed by three tuple(TT) method before stored into database. In online phase, coarse classification and locality sensitive hashing (LSH) are used to process the data and obtain candidate reference points (RPs).

In this paper, we propose a socalled Panoramic Human Detection (PHD) scheme to address the task of human detection in panoramic videos. Moreover, the PHD method is designed to detect humans by extracting multiple overlapping sub-images from each integral spherical image, where three-dimensional rotation of spherical images is employed to ensure consistency of sub-images. Two detection box filters are designed for removing redundant boxes. Our PHD method is capable of accomplishing the task of human detection in various panoramic video types.

The proposed method requires SDN control plane to periodically collect attributes of wireless networks so as to evaluate network performance. Considering varied types of services have different requirements and users have different preferences, fuzzy analytic hierarchy process (FAHP) and multi-path transmission control protocol (MPTCP) are applied to select the most appropriate target network and execute seamless handover, respectively. Compared to existing methods, the proposed method jointly considers service requirements, user preferences, and mobility management for network selection and guarantees service continuity during vertical handover. Simulation results show that the proposed method makes a comprehensive decision on network selection. In terms of handover times, the proposed method achieves up to 17.4% and 4.5% reduction compared to received signal strength based algorithm and fuzzy multiple criteria group decision making based algorithm, respectively.
