This parallel algorithm is based on a serial DPLL (digital phase locked loop) carrier recovery feedback architecture and a novel refined phase estimation module. To archive high speed communication, parallelization of serial DPLL carrier recovery algorithm is presented; to guarantee high accuracy, a refined phase estimation design is proposed. A 32 parallel baseband simulation model of 16QAM modulation is performed on MATLAB platform to validate the proposed algorithm. Simulation results demonstrate that the performance loss of EVM (Error Vector Magnitude) introduced by the proposed algorithm is less than 0.3%, which is only half of the traditional coarse compensation algorithm.","PeriodicalId":244952,"journal":{"name":"2018 IEEE 18th International Conference on Communication Technology (ICCT)","volume":"206 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":"116403271","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}

There are many scheduling systems in use, however, their functions are not perfect and cannot meet the needs of users. This paper designs a novel architecture of scheduling system for big data framework. The system has basic scheduling functions, such as algorithm job assignment, job priority scheduling, job result management. It supports three algorithms to schedule jobs: scheduling-in-order algorithm, scheduling-by-priority algorithm, and scheduling-by-resource algorithm, meanwhile implementing dynamic switching of these algorithms. The system has a graphical interface which greatly facilitates interaction between the system and the user.","PeriodicalId":244952,"journal":{"name":"2018 IEEE 18th International Conference on Communication Technology (ICCT)","volume":"5 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":"116982915","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}

Vehicles can be clustered together to ease the management, increase the effectiveness and capability of vehicular cloud. Clustering would allow these vehicles to pool their resources to serve the upper layers of the network infrastructure. This paper investigates the trends and state of the art of vehicular clustering in the past 5 years especially for parked vehicles in fog computing paradigm. It was observed that static and dynamic clustering are the two common methods, albeit dynamic clustering is more common.

To ensure detection accuracy, a line scan camera is used to capture the images of an LCD with more than 200 million pixels. Therefore, a tiny sub-pixel component of an LCD is mapped into many pixels in an image. The quadrant gradient operator is proposed to adjust gradient direction dynamically in different quadrants. Our method can directly detect sub-pixel component defects without extra operation to deal with edges. To detect defects efficiently and automatically, related parameters are estimated using a small random sampled sub-image. The projection method estimates the spaces between sub-pixel components, based on which the sample size and the defect area threshold can be estimated. Theoretical analysis and experimental results show that the proposed algorithm can accurately detect sub-pixel component defects in linear complexity O($n$).","PeriodicalId":244952,"journal":{"name":"2018 IEEE 18th International Conference on Communication Technology (ICCT)","volume":"141 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":"116051511","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}
