However, unsupervised learning with CNN attracts less attention than supervised learning. In this work, we use deep convolutional generative adversarial neural networks (DCGANs) to generate images. The model is trained by various star and galaxy images from Sloan Digital Sky Survey. In this paper, we also took a gird search to choose the best value for hyper-parameters and several methods to help to stabilize the training process and promise a good quality of the output. Based on several experiments, we demonstrate that our approach keeps the training procedure stable and the generator and discriminator are both good for unsupervised leaning.","PeriodicalId":367029,"journal":{"name":"2018 10th International Conference on Advanced Infocomm Technology (ICAIT)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130602369","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 changing polarization, wavefront of the laser after transmission over the atmospheric channel is analyzed, and the influence on the intermediate frequency (IF) signal is also analyzed. The results show that the polarization state of the laser is slowly changing after 1.3km transmission. When the polarization state of the signal light is controlled, the peak value of the output IF signal is increased by 0.5V and the mixing efficiency increased by 19%. The slowly changing of wavefront can directly affect the coupling efficiency of spatial light coupling into the fiber. Importantly, after the wavefront correction, the coupling efficiency is increased by 30 times, and the peak value of the IF signal is increased by 1V, thus, the mixing efficiency is increased by 20%. Moreover, both ends of the communication can complete continuously and smoothly transmission of the video signal, and the bit error rate of the communication system is below 10-9.","PeriodicalId":367029,"journal":{"name":"2018 10th International Conference on Advanced Infocomm Technology (ICAIT)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123614763","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 scheme is carried out using two steps: partitioning MS into groups in terms of covariances of each group; harnessing a two-stage beamforming: a precoder to mitigate inter-group interference by spatial correlation and a mutli-user precoder to counterbalance intra-group interference. Dual polarized massive MIMO aims to stave off the spatial constraint of 5G massive mimo. Diverging from pervious contributions which equally distribute MS into groups, this paper focuses mainly on an adaptive MS clustering algorithm for massive mimo JSDM scheme to optimize system performance.

Based on channel modelling of Quadriga which follows a geometry-based stochastic channel modeling approach, the proposed space time code is applied in the uplink of an industrial communication system. Simulation results show that the proposed code outperforms Alamouti code for Industrial Automation. The bit error rate (BER) performance demonstrates that the achieved coding gain for the proposed code is higher than Alamouti code. Furthermore, a low complexity decoder based on minimum mean squared error is designed at the receiver side. The proposed space time code is designed basically for increasing the reliability and robustness in industrial communication systems where BER of 10–9 is demanded. The proposed code provides superior performance against the state-of-the-art space time code systems.","PeriodicalId":367029,"journal":{"name":"2018 10th International Conference on Advanced Infocomm Technology (ICAIT)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122229796","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 algorithm is based on a newly proposed edge coloring method, called complex coloring. The route assignment in three-stage fault-tolerant Clos networks is formulated as an edge coloring problem of bipartite graphs. The extra switch modules in the middle stage of fault-tolerant Clos networks provide additional colors for edge coloring. In complex coloring, those redundant colors help to reduce the running time of the coloring process. Therefore, as the number of extra switch modules increases, the time complexity can be substantially improved along with the reliability of switching systems. The performance of our algorithm has been verified by extensive simulation experiments.","PeriodicalId":367029,"journal":{"name":"2018 10th International Conference on Advanced Infocomm Technology (ICAIT)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128544942","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 main candidate technologies for V2X communications are dedicated short range communication (DSRC)/IEEE 802.11p and long-term evolution (LTE), each of which has its own strengths and weaknesses. DSRC provides low-latency direct connectivity, but suffers from serious link degradation and reliability issues. On the other hand, LTE is able to provide high capacity data transmission, while its latency remains an issue due to the long transmission time interval. Integrating these two radio technologies as a heterogeneous solution is promising to complement each other and support V2X applications with differentiated service requirements. This paper proposes a service-aware radio access technology (RAT) selection algorithm that enables a heterogeneous LTE/DSRC solution, where LTE and/or DSRC are selected according to services. Each vehicle is assumed to be equipped with both LTE and DSRC interfaces. The heterogeneous solution selects RAT based on the services requirements with consideration of the networks performance. The solution is implemented with integration of the C-ITS standard and validated through the OMNet++ and SUMO based network simulator. A see-through scenario, where a fleet of vehicles require real-time video data sharing to assist efficient driving, is considered. The simulation results demonstrate that the proposed approach outperforms the purely DSRC approach significantly and is able to simultaneously support safety message transmission with low latency, video streaming with high bandwidth requirements, and other applications with different service requirements.","PeriodicalId":367029,"journal":{"name":"2018 10th International Conference on Advanced Infocomm Technology (ICAIT)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129200505","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}
