The majorities of existing dehazing methods rely on the dark channel prior (DCP) assumption and therefore share two mains limitations; the model is invalid when the scene is intrinsically similar to the atmospheric light and the DCP method suffers from high computational cost to refine the transmission map. In this paper, we propose a fast single image dehazing based on color cube constraint based on new haze imaging model to overcome these two limitations. The thickness of the haze can be estimated effectively, and a haze-free image can be recovered by adopting the new method and the new haze imaging model. In this method, we first design a new haze imaging model which enables us to represent the hazy image inside a color cube according to the concentration of the haze. Then, to get an accurate value of the global atmospheric light we took the maximum value of each RGB color channel. Next, we propose a simple but very powerful prior or method called variation of distance prior (VOD), which is a statistic of extensive high resolution outdoor images. Using this prior combined with the designed haze imaging model and improved global atmospheric light, we can directly estimate the transmission map and restore a high quality outdoor haze-free image. The experimental results show that our model is physically valid, and the proposed method outperforms several state-of-the-art single image dehazing methods in terms of effectiveness robustness and speed.","PeriodicalId":199874,"journal":{"name":"2017 IEEE 17th International Conference on Communication Technology (ICCT)","volume":"31 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":"122675138","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}

From the point of view of physical layer security, this paper analyzes the propagation characteristics, channel parameters and channel model of millimeter wave, and probes into the problem of passive eavesdropper in MISO communication scene. The main work includes: firstly, introduce the multipath propagation characteristics of millimeter wave, using beamforming and artificial noise broadcasting as a secure transmission mechanism. Secondly, a power allocation strategy based on artificial noise under the condition of inaccurate CSI is proposed to meet the QoSs (service quality requirement) constraints both at destination and eavesdropper so as to guarantee target secrecy probability. Both power constrained and power unconstrained systems are considered. The simulation results show that the outage probability-based method is simpler and more efficient than the existing second — order-statistic-based method.","PeriodicalId":199874,"journal":{"name":"2017 IEEE 17th International Conference on Communication Technology (ICCT)","volume":"1 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":"128658339","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 traditional binary graph based interference model cannot describe the cumulative interference relations, which are common in D2D networks. Therefore, we use the hypergraph model to depict the complex interference among the low powered and densely located D2D pairs. Consider the dynamic nature of the D2D communication, each D2D pair may frequently change between the active and silent state. Therefore, the network topology changes dynamically according to the combination of active D2D pairs. In order to reduce the cost and the delay caused by frequently updating access policies, we make the allocation of spectrum access aiming at optimizing the expectation of long-term network performance. We formulate the spectrum access problem as a local congestion game to minimize the expectation of the MAC layer interference level, which can consequently optimize the network performance. Afterwards, a distributed learning algorithm was used to search the pure strategy Nash equilibrium of the game. The simulation results validate the superiority of the hypergraph game solution.","PeriodicalId":199874,"journal":{"name":"2017 IEEE 17th International Conference on Communication Technology (ICCT)","volume":"12 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":"121470758","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}
