For this reason, efforts are underway to protect tuna resources in countries around the world. In Japan, an upper limit value of the catch amount is set, and when there is a possibility that the catch amount may exceed the upper limit value, the fishing operation is refrained to protect tuna resources. The set-net fishing covered in this research is a passive fishing method, it is almost impossible to avoid or catch only certain fish species. In addition, if the fixed net fishing is prohibited, the income of fishermen is lost because of fish species other than tuna aren't also caught. In this paper, we propose a method aiming at compatibility between resource protection of tuna and income guarantee of fishermen. An acoustic image of the 30-minute interval obtained by the fish finder is divided into a plurality of divided images, and whether or not the response of tuna is included by convolution neural network (CNN). Finally, based on the identification result of the divided image, it is judged whether the acoustic data of 30 minutes includes tuna. In this paper, to evaluate the performance of the proposed method, we derived the discrimination accuracy of the proposed method, and we also estimated the tuna resource protection effect when applying the proposed method, and the decrease rate of catch.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124983310","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}

Okamoto, Naoto Horiike, Tetsuya Yamamoto","doi":"10.1109/WPMC.2017.8301884","DOIUrl":"https://doi.org/10.1109/WPMC.2017.8301884","url":null,"abstract":"Massive machine-type communications (mMTC) scenarios that can accommodate Internet of things (IoT) device communications are currently being considered for implementation in fifth generation mobile communication systems. To support the dynamic traffic present in mMTC systems, grant-free non-orthogonal multiple access schemes have been proposed. In these schemes, both system capacity enhancement and transmit protocol simplification are achieved, and an overloaded transmission of more than one hundred percent of the capacity of the number of transmit samples is conducted. However, demand still exists for more capacity to accommodate massive devices. On the other hand, a simple method for ensuring the security of mMTC systems is required to suppress the energy consumption of IoT devices and reduce the amount of signal processing required at the central receive stations. In this paper, to satisfy these requirements, we propose a novel grant-free sparse chaos code multiple access (GF-SCCMA) scheme for mMTC systems in which sparse code multiple access is supplied based on chaos signals and physical layer security is ensured. GF-SCCMA is a non-orthogonal multiple access scheme in which only pairs sharing common keys can decode data by utilizing a chaotic codebook of transmission sequences. Furthermore, the distribution of the output log likelihood ratio is improved by using chaos-based quasi-Gaussian modulation, and enhancement of the capacity is achieved for conventional schemes when the outer channel code is concatenated. The improved performances in terms of capacity and security are shown through numerical simulations.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114453102","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}

On the other hand, mobile network operators are facing a significant challenge of how to realize ultra-dense micro-cell networks in a cost-effective manner. Recently, a new concept of network sharing toward multi-tenancy networks has been proposed and studied. In this concept, network resources including the BS (Base Station) are shared by multiple operators, resulting in significant cost reduction. In this respect, the shared BS needs to support several RATs (Radio Access Technologies) including mmW bands for providing a variety of communication systems. In this study, we prototype a shared BS supporting mmW bands based on the LTE system, by applying the frequency conversion technology to the off-the-shelf LTE eNB. This shared BS is mainly composed of an IF transceiver unit for the 4.5 GHz band and RF converter units for 28 GHz and 32 GHz bands. In addition, by applying the same architecture to the off-the-shelf UE, we successfully demonstrate the data transmission between the shared BS and the UE in 4.5 GHz, 28 GHz, and 32 GHz bands.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"80 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113971909","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}

To improve the user's quality of service (QoS) in that systems, in the present study, we propose a user cooperation aided clustering approach based on device-centric architectures and enable the multi-user multiple-input multiple-output transmissions with non-reciprocal setups. We actively use device-to-device communication techniques to achieve the sharing of user information and try to form clusters on user side instead of the traditional way that performs clustering on base station (BS) side in data offloading. We further adopt a device-centric architecture to break the limits of the classical BS-centric cellular structure. Moreover, we derive an approximate expression to calculate the user rate for LS-DASs with employment of the zero-forcing precoding and consideration of inter-cluster interference. Simulated and numerical results indicate that the approximate expression predicts the user rate with a lower computational cost, and the proposed approach provides better user experience for, in particular, the users who have unacceptable QoS.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131528729","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}
