VLC in indoor energy management is attractive due to characteristics that data are transferred through light and possible to be spatial security and localization. Variable pulse position modulation (VPPM) especially is suitable for the indoor energy management because of supporting a full dimming range and being implemented simply. This paper proposes a timing tracker for timing synchronization in the VPPM-VLC system. The proposed timing tracker is evolution of the early-late detection to the VPPM-VLC system by considering characteristics of the VPPM-VLC signaling in perspective on the timing tracker. This paper describes design results for a VPPM-VLC receiver with the proposed timing tracker, and presents behavioral simulation results for the verification of the proposed timing tracker. The simulation results shows that the proposed VPPM-VLC timing tracker estimates the timing-offset and compensates timing mismatch through buffer control.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132256453","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 design the system and evaluate the interference to other radio systems, propagation characteristics should be clarified for various usage environments. In this paper, propagation characteristics of path loss and r.m.s. delay spread are described based on measurement results in a viaduct environment. Path loss coefficients are extracted at different antenna heights compared with the side wall height of viaduct for a link budget design and it is validated by ray trace simulation. The cumulative distribution of delay spread is also analyzed for physical layer design.

The 5G (5th generation mobile communications systems) requires that base stations effectively receive small-size packets but massive uplink signals transmitted by the IoT devices.

We have evaluated channel estimation techniques and interference suppression and cancellation techniques by computer simulation. However, we have not evaluated the techniques on real machine yet.

Energy detection as a conventional CS is possible to detect unknown signals but so sensitive to noise variance that only a coarse spectrum sensing is performed in a short time. This paper proposes a novel CS for fine sensing based on LTE decoding in context of spectrum sharing in LTE systems among different operators by utilizing a prior knowledge of a control channel for resource scheduling. Numerical experiments show that the proposed method can achieve significant performances in terms of miss detection rate, false alarm rate, and the average of these.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130180651","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 study investigates the consequences on the accuracy of this approach. A simulation-based assessment is performed, where a single link is considered. The received signal strength is used to estimate the distance between LED and photo-diode. Results are obtained for different phosphor coated LEDs and photodiodes. It is shown that neglecting the wavelength dependency results in distance estimation errors in the order of 10 %. This severe degradation would undermine the achievable accuracy of VLP systems (order of centimeters). The result shows that regardless the used photodiode, LEDs with a high correlated color temperature are more prone to distance estimation errors in comparison with low correlated color temperature LEDs.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129119452","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 been also clarified that Digital FBCP is efficient in not-only single-site but also multi-site environment by introducing extended precoding technique. Although the previous works evaluate only in computer simulations, this paper aims to evaluate real-field performances by using 5G low-SHF-band massive MIMO prototype.

The new developed model enables the application of QoE as a possible network optimization criteria. Furthermore, it is showcased a generic framework to optimize antenna physical parameters. Using this framework, an algorithm was implemented which empowers the network MOS estimation by using the developed QoE model. A Root Mean Square Error (RMSE) of 9% was achieved, on the MOS prediction, using the developed model. Concerning the MOS antenna physical parameters optimization, it resulted in an average network performance gain of 5% comparatively to a interference control generic approach.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122705925","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 user experience of traditional service system based on content delivery network (CDN) and peer to peer (P2P) is limited by the bandwidth and the service ability. These technologies mostly concentrate on content servers and personal computers rather than routers and devices in the network. In this paper, we propose an in-network service system by taking full advantage of the smart routers and edge devices to relieve the load of CDN. We mainly do the following works. 1) We propose the basic architecture of the in-network service system and deploy it on a real network environment. 2) We introduce a hybrid node management algorithm for large scale, flexible, high churn network to manage the smart routers with the edge devices. 3) We design a file self-diffusion algorithm for content delivery. The evaluation shows the high performance of the hit rate of service using the proposed system. In the experiment, up to half of the user requests can be serviced by the proposed system without accessing the CDN.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"2 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120915342","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}
