However, because the propagation of Wi-Fi signals is greatly affected by the serious NLOS (non-line-of sight) effect for indoor environment. Therefore, the accuracy measure is deteriorated due to random NLOS effect in indoor wireless communication. In this paper, we propose a localization algorithm which is different from existing algorithms because no priori knowledge is required about NLOS conditions when working with the proposed algorithm. It utilizes both TOA (time-of-arrival) and received-signal-strength (RSS) measurements to get an optimized range of data based on the difference of two geometric area. And, then substitute this optimized data into the triangle centroid algorithm to perform positioning operation. Simulation results show that the proposed algorithm can efficiently reduce the error due to NLOS effect and achieve higher accuracy of localization as compared to other conventional algorithms.","PeriodicalId":158877,"journal":{"name":"2016 8th IEEE International Conference on Communication Software and Networks (ICCSN)","volume":"296 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134179910","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 substrate of this attenuator is high resistance silicon and the TaN thin film is used as resistors. RF MEMS switches have excellent microwave properties to reduce the insertion loss of attenuator and increase the insulation. Distributed attenuation networks employed as fixed attenuators have the advantages of smaller size and better performance in comparison to conventional π or T-type fixed attenuators. Over DC-20GHz, the simulation results show the attenuation flatness of 1.52-1.65dB and the attenuation range of 15.35-17.02dB. The minimum attenuation is 0.44-1.96dB in the interesting frequency range.

This paper investigates uplink resource sharing between multiple D2D links and CUs. Upon guaranteeing the quality of normal cellular communication, we try to explore the full benefit of D2D communication by allowing multiple D2D links to share the same spectrum resource made available by the CU, which, however, leads to a difficult nonconvex optimization problem. We propose an efficient algorithm to jointly optimize the transmit powers of the D2D links and the CUs.

Firstly, this paper selects 30 feature points from the 113 feature points of Candide-3 face model to characterize face, which improves the efficiency of recognition algorithm obviously without affecting the recognition accuracy. With the significant advantage of the characterization of essential features by learning a deep nonlinear network, this paper presents a stacked denoising autoencoder algorithm model based on deep learning which improves neural networks model. This algorithm conducts the unsupervised preliminary training of face depth data and the supervised training to fine-tuning the network which is better than neural network's random initialization. The experiment indicates that compared with real face data, the reconstruction face model has a small matching error by using SDAE algorithm and it achieves an excellent face recognition effect.","PeriodicalId":158877,"journal":{"name":"2016 8th IEEE International Conference on Communication Software and Networks (ICCSN)","volume":"2019 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114661508","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}

But regard to the existing DPLL systems, both the range of the locked phase and the running speed can't meet the needs of the application in reality. The heart of the matter is the constraint of algorithm and structure. In order to improve the performance, we present a new all-digital phase-locked loop (ADPLL) in this paper. We adopted frequency tracking algorithm and phase tracking algorithm to composite frequency multiplying signal and phase-locked signal in a way similar to the DDS. All algorithms were loaded into a single CPLD. The CPLD which was customized to a DPLL has a good performance in the tests.

Conducting system tests in this laboratory environment is quite challenging, as the laboratory is supposed to be shared with regular classes. This manuscript details the use of desktop virtualization to deploy dynamically a virtual cluster for testing and ad-hoc purposes. The virtual cluster can support an environment completely different from the physical environment and provide application isolation essential for separating the testing environment from the regular class activities. Windows 7 OS was running in the host desktops, and VMware Workstation was employed as the desktop virtualization manager. The deployed virtual cluster comprised virtual desktops installed with Ubuntu Desktop Linux OS. Lightweight applications using VMware VIX library and shell scripts were developed and employed to manage job submission to the virtual cluster. Evaluations on the virtual cluster's deployment show that we can leverage on desktop virtualization to quickly and dynamically deploy a testing environment while exploiting the underutilized compute resources.","PeriodicalId":158877,"journal":{"name":"2016 8th IEEE International Conference on Communication Software and Networks (ICCSN)","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125206675","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 a practical antenna system, due to inevitable aging and heat distortion of the components, there exists an inconsistency between the designed Beam-forming Network (BFN) Weighted Matrix (WM) and the actual value of it. However, the complexity of BFN WM measurement is in direct ratio to the channel numbers of BFN. For large-scale phased array antennas, the measurement of the BFN WM requires burdensome work. To solve the problem, this paper proposes a novel efficient WM measurement method for BFN based on Direct Sequence-Code Division Multiple Access (DS-CDMA), which significantly reduces the complexity of the test by multi-port testing and parallel signal processing. Moreover, benefiting from the correlation characteristics of Direct Sequence Spread Spectrum (DSSS) signals, the measurement precision of the proposed method achieves 0.038 in amplitude and 0.511 in phase. This paper also discusses selections of DSSS codes. By borrowing the concept of Multi-User Detection (MUD), we proposed a special de-correlation algorithm to solve the problem of using non-orthogonal codes. Hardware implementation and practical tests have strongly demonstrated the feasibility and accuracy of the proposed method.","PeriodicalId":158877,"journal":{"name":"2016 8th IEEE International Conference on Communication Software and Networks (ICCSN)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130537943","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}
