Deep learning is a type of machine learning that consists of multiple layers in which raw data is taken as input. This study analyzes the AMC process with a deep learning approach. In this context, performances of LSTM (Long-Short Term Memory) and Bi-LSTM (Bidirectional LSTM) methods on the modulation classification problem are compared. Simulation results show that Bi-LSTM method has a higher performance than does the LSTM method.","PeriodicalId":312627,"journal":{"name":"2020 28th Signal Processing and Communications Applications Conference (SIU)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115368540","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}

A high-level synthesis (HLS) tool, most recently and actively being researched in several research groups, automatically generates an RTL description of the hardware architecture from a high-level (C/C++) program. However, application to be accelerated on the hardware via an HLS tool needs to be written in order to decrease the overall memory access latency by simply rewriting the code so that the reformatted loop structure will have more locality. In this paper, we present two case studies to decrease the memory access latency by improving the locality of a given application by reorganizing the memory access pattern of the application being accelerated via HLS on hardware that has a cache. We also emphasize the importance of locality in performance of hardware accelerators with our empirical results on a Zynq-based SoC platform.","PeriodicalId":312627,"journal":{"name":"2020 28th Signal Processing and Communications Applications Conference (SIU)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115425412","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 recent years, a parallel version of the PSO algorithm has proposed to solve complex application problems, and the situation has become the focus of researchers. Communication in this approach is ensured by the migration of particles between sub-population. In the parallel version of the PSO algorithm, parameters such as migration strategy, migration period, the topological structure must be determined. In this study, it was analyzed in which periods it would be more appropriate to perform migration procedures. In this context, the maximum number of iterations of 10000 is divided into three period intervals: 1000-3000, 3000-6000 and 6000-9000. Then, for cases where the number of threads is 2 and 4, the migration process is analyzed over these periods.","PeriodicalId":312627,"journal":{"name":"2020 28th Signal Processing and Communications Applications Conference (SIU)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121089606","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 test of the algorithm's resistance against different compression formats and different compression qualities was carried out. Frame deletion forgeries were performed in random sizes and locations on the videos obtained from SULFA and TRACE LIBRARY databases which used frequently in the literature. Forgery location was detected with 100% accuracy at uncompressed videos. In MPEG4 and H264 compressed videos, accuracies are %85 and %90 respectively.

In this way, many diseases can be diagnosed early and treatment processes can be closely monitored. On the one hand, the advancing technology allows us to demonstrate how the human brain reacts to various environmental stimuli. In this study, electroencephalography (EEG) technique was used to record the reactions of the brain to the imagination of cloves and mint odors. The distinguishability of brain responses to these odors was tested using pixel means of gray-level images obtained from Burg-based color spectrogram images. By using pixel means as an attribute, a classification accuracy of 82.5% was obtained with k-nearest neighbor. The results showed that the EEG signals that can occur when the brain imagines different odors can be distinguished.","PeriodicalId":312627,"journal":{"name":"2020 28th Signal Processing and Communications Applications Conference (SIU)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125102484","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}

However, it is not a nationalized technology and also suffers from jamming and spoofing attacks which makes it unreliable for standalone use in military systems. In this study, an alternative localization solution based on radio communication is developed without GNSS. This solution utilizes the time synchronization algorithm which is needed for preserving the network functionality. Several localization algorithms based on propogation delay measurements, which are mutually shared by the time synchronization algorithm, are studied. Better performing algorithms are integrated into the embedded software while employing the underlying waveform capabilities as much as possible. Therefore, a solution with advanced protection against electronic warfare is developed which requires no additional hardware. Studied localization methods are extensively investigated for various system parameters along with their resulting localization performance.","PeriodicalId":312627,"journal":{"name":"2020 28th Signal Processing and Communications Applications Conference (SIU)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125143457","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}

A robot needs to do navigation in its surrounding environment to be able to do exploration. In outdoor and indoor environments with obstacles around, sensing an environment and creating its map to do navigation is a common practice in robotic studies. An aerial vehicle is able to reach to a target position without crashing into static and dynamic obstacles, with the help of costmaps created in navigation applications. To prevent an aerial vehicle, which is trying to find a path to a target position, from getting crashed into other vehicles in applications with multiple aerial vehicles, that aerial vehicle needs to take into account the paths that found by other vehicles. In this way it's possible to prevent aerial vehicles getting crashed into each other. In this work, a simultaneous navigation application is developed for aerial vehicles that can build concurrent 3D multi maps. Experiments have been done in Gazebo simulation environment of ROS framework.","PeriodicalId":312627,"journal":{"name":"2020 28th Signal Processing and Communications Applications Conference (SIU)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123790061","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}
