Prototype network addresses this challenge by learning an embedding function from training set and applying the function to targets from test set with few samples, but the learned embedding function is not optimal relative to unknown tasks. To this end, this paper employs a type of triple attention mechanism called Transformer to transform the embeddings from task-agnostic to task-specific by establishing the dimensional dependency between labeled samples and targets to be identified in the task. The experimental results show that proposed method improves recognition accuracy by 24.92% in 5-way 1-shot task and 18.35% in 5-way 5-shot task, which verifies the effectiveness of the method.","PeriodicalId":352596,"journal":{"name":"2021 2nd Information Communication Technologies Conference (ICTC)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127441516","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}

Based on VLC, many attractive localization technologies are proposed, especially angle-of-arrival (AOA) algorithm. Existing AOA systems exploit optical receivers to detect the light power, but the receivers may not be arranged as the optimal orientations to reduce the localization error. In this letter, we employ an optimal optical omnidirectional angle estimator (OOAE) as the receiver, and a novel three dimensional (3D) localization algorithm is proposed, which requires low computational cost. Furthermore, we propose two supplemented methods to reduce the positioning error when more than two white light-emitting diodes (LEDs) are exploited. Experimental results show that the proposed algorithm can achieve centimeter-level accuracy, which would provide constructive insights for the design of AOA systems.","PeriodicalId":352596,"journal":{"name":"2021 2nd Information Communication Technologies Conference (ICTC)","volume":"226 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114423065","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 field trial result has shown the inter-cell interference caused by cell reference signal from surrounding LTE cells reduces the 5G system performance severely. In view of the fact that the traditional CRS-IC algorithms which increase the design complexity of UE receiver structures need to estimate CRS interference from the domain interfering cell and subtracted from the received signal sequentially, low complexity interference algorithm based on network assistance is considered as a promising technology for 5G commercial UE and network. In this paper, a novel interference mitigation algorithm for NR system is proposed to reduce the co-channel interference from LTE cell. The performance of proposed solution is evaluated and compared to the zero-power rate matching-based solution by means of link level simulations that follow the 3GPP guidelines. The simulation results show that the proposed solution can provide significant gains.","PeriodicalId":352596,"journal":{"name":"2021 2nd Information Communication Technologies Conference (ICTC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123088940","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}
