The research of belief propagation list (BPL) algorithm based on permutation factor graph has also made great progress, but the complexity of decoding process is still too high. In order to compromise performance and complexity, in this work, we focus on the iterative convergence of BPL decoding algorithm, and propose an early termination BPL algorithm based on multiple CRCs. The results show that the improved BPL decoding scheme can provide higher throughput and achieve similar decoding performance with the existing BPL decoding under the same simulation condition.","PeriodicalId":124337,"journal":{"name":"2020 IEEE 3rd International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114368950","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 feed the Circularly-polarized array antenna, a compact feeding network based on Wilkinson power divider is also proposed, achieving four-way power splitting and 90° phase shifting. By this way, a sequential rotation array antenna with compact size (0.21λ0× 0.21λ0 × 0.006λ0), ease of integration, low fabrication cost and good performance is realized.","PeriodicalId":124337,"journal":{"name":"2020 IEEE 3rd International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116029852","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 lower band which covers from 2.14GHz to 2.49GHz is mainly controlled by the size of rectangular loop. The middle band of 3.15GHz-4.06GHz is controlled by the dimension of T -shaped strip.

ERI is in the pilot research stage now in China, but the release of the standard is accelerating its promotion. The performance evaluation of car-related RFID products is often accomplished by test and trial method currently. The test results are seriously affected by irrelevant environmental factors, making it impossible to carry out scientific repeatable experiments. In this paper, the communication channel model of ERI system in the highway traffic scene is modeled based on the ray tracing method. In order to accurately establish the model, we conducted a simulation analysis on the influence of factors such as antenna pattern, polarization mode, ground material, and environmental noise on the received signal power and tag reading distance. Files generated based on the model in this article can be loaded onto the channel simulator, so as to build an ERI test system with reproducible test results which has important application value.","PeriodicalId":124337,"journal":{"name":"2020 IEEE 3rd International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122179031","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}

It has found that computer vision technology, natural language processing technology and brain-computer interface technology have become the focus of artificial intelligence research. From the perspective of the number of key core technology patents, intelligent chip technology and computer vision technology are the key research and development objects. The Artificial intelligence question and answer mode are mainly reflected in the change of interactive mode and its intelligence, in which core technologies and key algorithms are the focus.

In this paper, we propose a new kind of tasks based on occupancy, namely high correlated occupancy mining, by introducing correlated occupancy into the support-based mining framework.
