Its application scenario lies in a small-scale Internet of Things environment. These devices are usually small and exquisite and easy to carry. Since these devices are powered by the battery inside, it is an important issue for BLE to reduce power consumption and extend usage time without reducing performance. The data communication of BLE devices can only start after advertising, scanning, and connecting. Therefore, the configuration of advertising and scanning parameters of BLE devices is another important issue that affects performance. For advertising, there are advertising interval, advertising event, random delay, etc. For scanning, there are scan window, scan interval, etc. The combination of different parameters can lead to a large variation in the neighbor discovery process (NDP) time. In this paper, we investigate and analyze the relationship between parameters and the discovery latency. We show that unbounded latency could occur when the advertising interval is equal to an integer multiple of scan interval minus the average random delay. We further propose a method to bound the discovery latency by adjusting the parameters as appropriate during the discovery process.","PeriodicalId":104014,"journal":{"name":"Proceedings of the 4th International Electronics Communication Conference","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130783616","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 tackle this issue, an improved ABS technology based on interference suppression was proposed in this paper. Firstly, the channel parameters are estimated in the ABS frame and sent back to the micro base station (BS). Secondly, the micro BS uses the estimated parameters and the synchronized digital signal of the macro BS to calculate the pre-processed digital signal. Finally, the predistortion part of the signal from the micro BS and the signal from the macro BS cancel each other out at the terminal. The proposed method can alleviate the interference of the macro BS to the edge users of the small cell, and significantly reduce the proportion of ABS frames in the macro BS, thereby improving the communication performance of the macro cell.","PeriodicalId":104014,"journal":{"name":"Proceedings of the 4th International Electronics Communication Conference","volume":"39 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120927329","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 order to adapt to the development, the concept of \"reconfigurable network\" is proposed to improve the robustness and expansibility of network service support. However, the reconfiguration of the routing switching platform represented by the upgrading of the architecture hardware system will bring great cost pressure to users. In order to reduce the operation and maintenance cost of the network system and improve the reliability of the network system, the reconfiguration of the routing switching platform gradually transits and develops to the direction of retaining hardware equipment, upgrading software system and updating some equipment. In this paper, it analyses and design the security architecture of the open reconfigurable routing and switching platform to meet the demand for high speed, high capacity and high efficiency processing of network information, especially the demand for secure data transmission and exchange. For the prominent and critical security issues and matters in the reconfigurable routing and switching platform, the security reconfiguration method of platform components and components is constructed, and the system of components is analysed and modelled. Finally, the effectiveness and necessity of security techniques applied in the open reconfigurable routing and switching platform are verified.","PeriodicalId":104014,"journal":{"name":"Proceedings of the 4th International Electronics Communication Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128038717","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}

Broadband Communication such as millimeter wave (mmWave) communications and teraHertz (THz) communications are both key enablers of 6G networks. Due to the inherent nonlinearity of the radio frequency (RF) components, such as power amplifiers (PAs) and mixers, larger bandwidth with high-speed modulation would cause serious nonlinear distortion, which would significantly degrade the quality of the transmission signal.If simply transmitting signal at a power level with large back-off, the power efficiency of the transmitter would dramatically drop to a unacceptable level, which would deviate from green communications with less power consumption.The digital pre-distortion (DPD) technique usually be used to correct the nonlinearity from these RF component and integration module. However, in the conventional DPD, the sampling rate of analog-to-digital (ADC) and digital-to-analog (DAC) is ten times as bandwidth for the transmitting signal, which is impractical for broadband applications, such as THz communication. Therefore, this paper proposed a novel linearization method to use ADC and DAC with low sampling rates. A nonlinearity correction model with under sampling signals are derived. Finally, simulation results verify the effectiveness of the theoretical analysis and demonstrate that the proposed linearization method could improve the EVM from 9% to 2% for a 64-QAM signal of 2 GHz bandwidth.","PeriodicalId":104014,"journal":{"name":"Proceedings of the 4th International Electronics Communication Conference","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127785649","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}
