The low cost has been achieved by excluding any monolithic microwave integrated circuits thus all of the system blocks were designed using discrete components. The market price of all semiconductor components used in this project: radio frequency (RF) transistors, diodes, operational amplifiers, and voltage regulators, is about 9 USD when buying them in minimum quantity. The discrete nature of the system makes it an excellent tutorial on FMCW radar design and RF circuit techniques.","PeriodicalId":158890,"journal":{"name":"2018 International Conference on Communications (COMM)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114906255","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}

But the lack of implementations that can be used in practice has reduced its impact. This paper introduces a new and original implementation of the Gamma formalism based on set rewriting, that has the potential of reviving it from a practical point of view. The multisets are the basic data structure used by the Gamma formalism, so the quality of any implementation for this formalism depends on the quality of the implementation of the multiset. Set rewriting enables term rewriting on all the terms of a given set in a single rewriting operation, thus executing several rewriting operations in parallel and at the cost of a single one. The use of set rewriting to implement the multiset and the actions of the Gamma formalism seems to be a natural match, as they are both based on non -deterministic, parallel processing. The paper describes the new implementation and presents a proof of concept for the Gamma program for sorting numbers.","PeriodicalId":158890,"journal":{"name":"2018 International Conference on Communications (COMM)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122229761","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}

Although NLP schemes show better performance, their complexity is high.

A major step in implementing such a network is to design an architecture capable of meeting all the challenging requirements, to create interoperability with the existing networks and to be able to accommodate all new services and use cases. Our main contribution in this paper is the realization of a general architecture for a 5G network, from the mobile operator perspective. We have described the entities involved in this architecture with emphasis on virtualization and resource management part. We are proposing that the first deployable scenario under our 5G network will be Smart City, developed in H2 2018. That's why the paper presents also the main features of a 5G Smart City and describes a particular solution that will be developed within this city, Smart Lighting. In addition we have also synthesized, from the proposed architecture, a perspective of the functional model and business role for Smart Lighting use case, that is very important to us.","PeriodicalId":158890,"journal":{"name":"2018 International Conference on Communications (COMM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134162931","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}

One fundamental parameter of the any-communication signal is the information contained in the amplitude, frequency and /or phase change. This information is usually recovered using a detector based on the matched filter concept. Still, when it comes to the strong disturbed channels, the reference signal can be far from the received (expected) waveforms. Another application field is the communication intelligence (COMINT) when the recognition of communication signals is aimed. Using the concept of phase diagram representation of a signal, coming from the field of nonlinear dynamic systems, we aim to track the signal's parameters, providing a new method for the estimation of the frequency, phase and amplitude evolution in time. The main advantage of this approach is the capability of phase diagram representation to highlight the signal's phase continuity, very useful for an accurate tracking of the communication parameters.","PeriodicalId":158890,"journal":{"name":"2018 International Conference on Communications (COMM)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122407276","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}
