The OpenEAR toolkit is used to extract more than 6,000 features per speech sample. The features consist of 56 low level descriptors (LLDs) and their Delta and Delta Delta values, the corresponding 39 functionals. The language model training component is based on the Gentle AdaBoost algorithm. When tested on a group of 10 principally Indo-European languages, the language recognition system performs comparatively to other language recognizers. The UPGMA tree built from the interlanguage distances identifies the major subgroups of Indo-European. Genetic algorithms are also implemented to generate the language map on the 2D plane. Although some errors remain, the obtained language tree and map are indicators of language relationships. We discuss errors in our system and more generally perspectives for the use of sound file classifiers in historical linguistics.","PeriodicalId":158117,"journal":{"name":"2016 8th International Conference on Wireless Communications & Signal Processing (WCSP)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132456776","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, security and privacy have become major concerns in existing C/S based OSNs. In this paper, we propose a novel scheme called a Community-based P2P OSNs with Security Enhancement (ComPOSE) that supports cross-platform availability and reputation mechanism in stringent privacy requirements. For the first time, we formulate the privacy issue and design goals for P2P based OSNs. We firstly introduce broadcast encryption into P2P community-based social networks together with hierarchical encryption algorithms in order to decrease the system overhead. In ComPOSE, we employ the Open Directory Project to classify and encode groups. The RESTful web-services help to ensure cross-platform availability and transmission security. As a result, thorough security analysis and performance evaluation on experiments demonstrate that the ComPOSE scheme indeed accords with our proposed design goals.","PeriodicalId":158117,"journal":{"name":"2016 8th International Conference on Wireless Communications & Signal Processing (WCSP)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129637165","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 this paper, we manage the vehicle mobility by dividing one scheduling round into multiple segments, and investigate the resource allocation problem to answer the questions of which modulation and coding scheme (MCS) should be adopted for each flow in each segment, and how to schedule the radio resources among all the flows. We consider two kinds of multicast services. For the multicast service to cover all the recipients, we formulate the problem as a resource scheduling problem with fixed MCS profile, and propose a k-commodity packing based approximation algorithm to solve it with low complexity. For the multicast service with adaptive recipients, we notice that the number of valid MCS profiles for each flow is limited, and propose a heuristic algorithm to search for proper MCS profile assignments. The simulation results verify the efficiency of the proposed scheme.","PeriodicalId":158117,"journal":{"name":"2016 8th International Conference on Wireless Communications & Signal Processing (WCSP)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128054784","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}

By phase transform, the steered response method (SRP-PHAT) is robust; with the noise increasing, the performance of the method becomes bad. Using principal eigenvector, the steered response power (SRP-PE) method is better than SRP-PHAT. In this paper, we propose an improved SRP-PE method, which only uses the frequencies with small ratio between the second and the first eigenvalue to estimate the sound source location. Simulation results show that similar to the SRP-PE algorithm, the localization accuracy of the improved SRP-PE method is better than the SRP-PHAT method; moreover, compared to the SRP-PE, the proposed algorithm has lower computational complexity.","PeriodicalId":158117,"journal":{"name":"2016 8th International Conference on Wireless Communications & Signal Processing (WCSP)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115230269","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}

Furthermore, standard PF can be replaced by Rao-Blackwellized PF (RBPF) based on linear/nonlinear State Space models to produce more accurate means and variances for CI fusion. Unfortunately, the RBPF algorithm fails in conventional radar systems because their observations contain no information about the linear part of target state. To overcome such an issue, a Kalman Estimation based BRPF (KE-BRPF) algorithm is proposed to form a novel distributed CI fusion. In KE-RBPF, the correlation between linear and nonlinear parts of target state is investigated. Benefitting from this investigation, the linear part of target state is correctly tracked based on the nonlinear one. Finally, the simulations verify that our KE-RBPF-CI fusion outperforms other PF-based CI fusions, in terms of means and deviations.","PeriodicalId":158117,"journal":{"name":"2016 8th International Conference on Wireless Communications & Signal Processing (WCSP)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116761127","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 this method, source signals were second-order cyclostationary(SoC) after preprocessing, and this feature was helpful for identifying channel and separating source signals effectively in receiving terminal. We call it pPSoCBSS which is the abbreviation for preprocessing second-order cyclostationary BSS algorithm. pPSoCBSS is a good scheme for Wireless Statistical Division Multiplexing (WSDM). It had three steps: a)source signals preprocessing; b)channel identification; c)source separation. Preprocessing signals has three advantages in identifying channel: more exactly, anti-noise effectively, and without loss in underdetermined case. mathematic analysis and extensive simulation results confirm the validity and high performance of the algorithm.

In view of this, combining with the human visual characteristics, a color image enhancement algorithm based on tone-preserving was proposed. A determination function was added to the bilateral filter to estimate illuminance image more accurately and weaken over-enhancement. According to human visual masking effect, the improved gamma correction was utilized to correct the brightness of illumination image adaptively and the local contrast of reflection image obtained by division was enhanced based on local statistics. Besides, the final enhanced image was obtained by combining illumination image with reflection image, which can make image appear more natural.

The direction of research is focused on the RGB color space. There are few researches in other color spaces, such as HSV, L*a*b*, YCbCr. In this paper, we propose a color image encryption method in YCbCr color space. There is much information in Y channel but little information in Cb and Cr channel. Using this feature, we choose different encryption schemes. We first convert the color space from RGB to YCbCr. Then we encrypt the three channels separately. In Y channel, with Arnold cat map, we can do the preliminary image confusion, and then we use three-dimensional Lu chaotic map to do the further image diffusion. In Cb and Cr channels, we use DNA encoding and 1D Logistic chaotic map. Experimental results show that our color image encryption works well, our method in YCbCr space can compare with the RGB and L*a*b* space, and can resist brute-force attacks, differential attacks.
