As the newest video coding standard, HEVC achieves twice the compression ratio of H.264 under the same video quality. But meanwhile, it produces certain quality impairments, so it's necessary to do video quality evaluation on HEVC coding. This paper mainly refers to the no-reference algorithm based on the peak signal-to-noise ratio (PSNR) from ZhengYuan. The algorithm uses the Laplace distribution to build model for discrete cosine transform (DCT) coefficients. Moreover, since HEVC adopts four sizes of transform block, the algorithm uses the pixel block size weighted method to estimate quantization error to replace the pixel domain mean square error (MSE). Then compute the estimated peak signal to noise ratio (PSNR). Our experimental results shows that the estimated PSNR can reflect video quality well and has good accuracy, correlation and monotonicity with the actual PSNR.","PeriodicalId":243383,"journal":{"name":"2018 10th International Conference on Communication Software and Networks (ICCSN)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114211991","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}

At last, according to every node’s static topology and real-time linkstates, search the node’s dynamic routing table. This algorithm adopts distributive computation, on the basis of static routing, uses link states to obtain dynamic routing table. All of the routing processing are done by looking up table instead of calculating, which means it has better real-time efficiency and QoS guarantee.","PeriodicalId":243383,"journal":{"name":"2018 10th International Conference on Communication Software and Networks (ICCSN)","volume":"135 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123786555","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}

A carrier frequency offset estimation algorithm based on under sampling for THz communication is proposed in this paper. This algorithm utilizes methods including narrow band filtering (the bandwidth of filtered signal is only about 0.1% of the original signal bandwidth), under-sampling based on coprime sampling and second time estimation. For signal processing, we use FFT (Fast Fourier Transform) to achieve correlation operation on the frequency domain, which effectively reduce the computational complexity. The method we proposed significantly reduce the sampling rate as well as improve the estimation accuracy and thus can be applied to THz communication. The simulation results show that the algorithm can estimate a large dynamic range of the frequency offset at a low SNR with a low sampling rate, which reduce the difficulty of signal processing and hardware design.","PeriodicalId":243383,"journal":{"name":"2018 10th International Conference on Communication Software and Networks (ICCSN)","volume":"189 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116338173","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}

This paper focuses on quantitative performance analysis of zeroconf protocol. The analysis process contains two phrases: model construction and property verification. Since there exists competition relation among the hosts and their behaviors exhibit stochastic features, it is natural to model zeroconf protocol as turn-based stochastic game. Due to the absence of some necessary details of the original protocol, this paper also makes some assumptions about the model. The successful configuration probability and time cost are the most important concern of this protocol. This paper verifies maximum and minimum successful and unsuccessful configuration probabilities within certain periods. On the other hand, this paper also considers time cost to reach successful configuration. Experiments are performed with the tool PRISM-game which is for modeling and verification of stochastic games. Experimental results show that when the number of host is no more than 40,000, the performance of this protocol tends to be stable and when N is greater than 40,000, both the expected time cost for successful configuration and conflict probability will grow prominently.","PeriodicalId":243383,"journal":{"name":"2018 10th International Conference on Communication Software and Networks (ICCSN)","volume":"61 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130911372","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}
