In this paper, we study the problem of secure communication in a millimeter wave wiretap network. Two transmission protocols are designed to achieve the secure transmission in a sector zone. We give a comprehensive investigation of secrecy performance by analyzing each protocol in terms of secrecy outage probability (SOP), connection outage probability (COP) and secrecy throughput. Particularly, for the secrecy guard zone protocol, we analyze the influence of transmit power on secrecy performance and the results demonstrate that it is very important to set transmit power properly. For the secrecy guard zone protocol with artificial noise, in addition to analyzing the influence of transmit power on each performance metric, we also analyze the effect of transmit power allocation factor on the secrecy throughput, the results reveal that the power allocation of the AN and the information signal need to be properly set for increasing the secrecy throughput. Moreover, the influence of different millimeter wave frequency on the performance metric is also analyzed. Finally numerical results are provided to verify our theoretical analysis.","PeriodicalId":423073,"journal":{"name":"2018 10th International Conference on Wireless Communications and Signal Processing (WCSP)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126832661","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 solve this problem, a novel color image retrieval method based on improved fast affine matching is proposed, which combines color constants and hue and saturation (H-S) color features of special marks to perform the fine-grained retrieval of images. The proposed method overcomes the influence of illumination variation and deformation on vehicle images. Furthermore, with full use of vehicle annual inspection labels, vehicle retrieval can be separated from excessive reliance on vehicle license plates. We evaluate our proposed method on the ReIDcar dataset, which includes many low-quality vehicle images in a series of experiments, and the large-scale image dataset VehicleID. Experimental results demonstrate that the retrieval rate outperforms other traditional methods, verifying the feasibility and effectiveness of the proposed method. Experimental results demonstrate that the proposed method is superior to other synopsis methods in the processing speed and retrieval accuracy.","PeriodicalId":423073,"journal":{"name":"2018 10th International Conference on Wireless Communications and Signal Processing (WCSP)","volume":"183 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114936048","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}

Non-coherent detection is a kind of feasible CPM detection method if there is large phase noise or residual carrier frequency offset. Near-optimal non-coherent sequence detection, which is based on Viterbi algorithm, has a performance close to that of maximum-likelihood sequence detection (MLSD). However, near-optimal non-coherent detection of CPM is very complicated to be implemented, and it is even more difficult to achieve a high speed due to feedback in the process of calculating branch metrics, add-compare-select (ACS), updating the beginning phase and phase reference symbol. In this paper, we first review near-optimal non-coherent detection of CPM, and then we present a high speed design of FPGA implementation for near-optimal non-coherent detection of a 64 state, 4-ary, length-3T raised cosine (3RC) CPM on Xilinx XC7VX690T device. In our scheme, the frequency pulse truncation is used to simplify the CPM detection. We propose a feedback processing in parallel for different states of CPM trellis to achieve a low latency. Furthermore, we develop a recursive implementation architecture for the process of updating the beginning phase. We achieve the CPM bit rate of 25Mbps for the on-chip processing clock of 100MHz. The results of simulation shows near-optimal non-coherent detection performs much better the coherent detection when residual carrier frequency offset or phase noise exists. It is found that the implementation can achieve a degradation in the Eb/N0 from computer simulation of as small as 0.3 dB for an average BER=10-5.","PeriodicalId":423073,"journal":{"name":"2018 10th International Conference on Wireless Communications and Signal Processing (WCSP)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122780323","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 guarantee the best user experience, dynamic adaptive streaming over HTTP (DASH) is adopted as the de facto industrial technology, which can flexibly select the “proper” bitrate for each next video segment with the varying network throughput. In this paper, we propose a client-side buffer driven rate adaptation strategy which improves the real-time quality of experience (QoE) by answering to users’ differentiated QoE requirements at different buffer states. According to whether the downloaded video content is enough to resist bad network conditions, we define a startup state and a steady state of the buffer and take different rate adaptation goals for each state. For the startup one, filling the buffer as soon as possible helps improve users’ QoE the most. While for the steady state, our strategy aims at providing users with undisturbed viewing experience, which needs major concern over both the video quality and the rebuffering. Simulation results have shown that our strategy can effectively reduce the occurrence of rebufferings caused by the mismatch between requested video rates and varying network bandwidth, and attains standout performance on users’ QoE compared with classical rate adaption methods.","PeriodicalId":423073,"journal":{"name":"2018 10th International Conference on Wireless Communications and Signal Processing (WCSP)","volume":"237 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122864782","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 work, we study how to analyze delay and optimize offloading scheme of short packets in a mobile edge computing (MEC) system with both URLLC and eMBB services. To reduce computing delay for short packets, a processor-sharing (PS) server is deployed in the MEC system, where the total computing ability is equally allocated to all the packets in the server. As such, short packets can bypass long packets in the server. We derive a closed-form expression of the complimentary cumulative distribution function of latency experienced by short packets in the PS server, and minimize the end-to-end (E2E) delay of short packets by optimizing offloading probabilities subject to the reliability requirement. Simulation results validate our analysis and show that the PS server outperforms two kinds of first-come-first-serve servers in the scenarios with both short and long packets.","PeriodicalId":423073,"journal":{"name":"2018 10th International Conference on Wireless Communications and Signal Processing (WCSP)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114493880","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}
