In order to achieve this goal, it is necessary to understand the underlying physical propagation phenomenon in underground mines. Accurate and efficient channel models including large-scale fading characteristics are crucial for the design and performance evaluation of VLC systems. However, the characteristics of the underlying VLC channels have not been sufficiently investigated yet. In this paper, based on the recursive channel model, a path loss channel model is proposed precisely with the path loss exponent determined by three different trajectories in the mining roadway and working face environments. Taking different numbers of transmitters into account, both line-of-sight (LoS) and non-line-of-sight (NLoS) scenarios are considered. Our results demonstrate that the path loss exhibits a linear behavior in log-domain when curve fitting technique is applied. An expression for path loss as a function of distance is derived. Finally, root mean square (RMS) delay spread has been investigated and analyzed.","PeriodicalId":418396,"journal":{"name":"2017 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130835929","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}

Researchers recently note the potential of social network analysis to design wireless networks more efficiently. In this paper, we present a very original view to take advantage of clustering coefficient in social network analysis to develop more effective ad hoc networking without the need of global network information. We start from random geometric graph to view the communication range of a wireless node as a disc, which is equivalent to examining the outage probability of links. Under stochastic geometry analysis of interference, the impacts of density and traffic of nodes on the connectivity can be therefore analyzed. Similar to the structural holes in social networks, the ad hoc networks suffer from the void region problem in the geographical routing, which is even more harmful in ultra dense networking environments. Discarding the detailed global routing table, we surprisingly show that the local estimation of clustering coefficient of nodes can significantly improve the void problem handling to result in more effective ad hoc networking.","PeriodicalId":418396,"journal":{"name":"2017 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"C-36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127237294","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}

Continuous measurement campaign was conducted on a city expressway through the complex dense urban area in Wuhan, China. Small-scale channel characteristics including power delay profile (PDP), amplitude fading distribution, K-factor, delay spread and doppler shift were obtained, respectively. Specifically, the cumulative distribution function (CDF) of root mean square (RMS) delay spreads and RMS doppler spreads in non-congestion scenario and congestion scenario were all fitted well with Lognormal distribution. We also found that different intensity of traffic and speed of vehicles have little effect on RMS delay spreads, but have a big impact on RMS doppler spreads. According to estimation outcomes, the V2V channel characteristics in Chinese urban scenario were different from the previous measured results in European cities. All of these conclusions in this paper can provide references to design the wireless communication system for V2V channel.","PeriodicalId":418396,"journal":{"name":"2017 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"360 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125648433","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 scheme utilizes joint polarization-QAM to promote energy efficiency by taking the advantages of both QAM and polarization modulation in the linear and nonlinear areas of PA, respectively. However, the energy efficiency is effected by the changes of the factors such as modulation orders, PA characteristics, channel of polarization mode dispersion, channel compensation matrix and symbol error rate (SER) and data rate requirements. In addition, they can also interact with each other. To optimize energy efficiency, the energy efficiency maximization problem regarding these factors is formulated, and an improved algorithm based on differential evolution is proposed to obtain competitive performance when solving the problem. Therefore, the energy efficiency optimization scheme in this paper enables not only adaptation of modulation as adaptive polarization-QAM scheme, but also joint adjustment of PA characteristics and channel compensation matrix to achieve higher energy efficiency. The simulation results under the same SER threshold show that the energy efficiency of proposed energy efficiency optimization scheme based on improved differential evolution with joint polarization-QAM can be improved by up to 43% compared with adaptive polarization-QAM scheme in OFDM systems.","PeriodicalId":418396,"journal":{"name":"2017 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"58 20","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134005297","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 this paper, we propose a cognitive two-path relay (TPR) network with the capability of power splitting (PS)-SWIPT. With the aid of PS, the successive source and relay transmissions can overcome spectral efficiency loss compared with half-duplex (HD) relay-assisted PS-SWIPT networks. An optimization problem is formulated, with jointly optimizing the PS factors of two relays to maximize the minimum signal-to-interference-plus-noise ratio (SINR) at the destination during two successive time slots. Through ratiocination and proving, the optimal solutions can be obtained by iterative methods. In consideration of inter-relay interference (IRI) cancellation, we also investigate the optimal PS factors under the condition of sufficiently small IRI channel gains. The simulation results demonstrate that, in the proposed scheme, the optimal PS factors with IRI cancellation are almost identical with the solutions with IRI when the IRI channel gains lower than a certain threshold, which can be set as the initial values of the iteration to reduce the iteration times in practical networks.","PeriodicalId":418396,"journal":{"name":"2017 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"179 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133576466","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}
