A possible solution to these issues could be small cell densification combined with utilizing access points carried by Unmanned Aerial Vehicles (UAVs).

It is essentially an enhanced version of the standard TXOP mechanism initially introduced by the IEEE 802.11e amendment, specifically engineered to improve performance of the Downlink Multi-User Multiple-Input-Multiple-Output (DL MU-MIMO) technology. DL MU-MIMO transmissions with TXOP sharing are performed only by the Access Point (AP) allowing multiple frames from multiple traffic classes to be transmitted simultaneously towards multiple users in the downlink. However, in the reverse path, acknowledgments must be transmitted sequentially. The default acknowledgment scheme selected by the IEEE 802.11ac is the Block Acknowledgments (BlockACK) which is a poll-based approach. In this paper, we investigate the application of an acknowledgment-free scheme, known as No Acknowledgment (NoACK), during DL MU-MIMO transmissions in IEEE 802.11ac Wireless Local Area Networks (WLANs). Its impact on the overall achieved throughput is evaluated through an analytical study.","PeriodicalId":383018,"journal":{"name":"2018 41st International Conference on Telecommunications and Signal Processing (TSP)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123649226","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 detect the signals transmitted from BS, users should have their channel information. Instead of assuming that each user can perfectly know the expected value of its effective channel gain, users use least-square (LS) estimation to estimate their effective channel gains through downlink training. However, the estimated effective channel gains will be polluted by interference from other cells due to the limited pilots, which will degrade the system performance if it is not treated well. To alleviate it, a novel pilots allocation scheme is proposed in which users who use the same uplink pilot sequence are allocated with mutual orthogonal downlink pilots. With this scheme, we prove for maximum-ratio transmission (MRT) and zero-forcing (ZF) precoding that the relative estimation error of the effective channel gain tends to zero when the number of BS antenna goes to infinity. Simulation results validate the efficiency of our proposal.","PeriodicalId":383018,"journal":{"name":"2018 41st International Conference on Telecommunications and Signal Processing (TSP)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127636650","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 novel minimum mean square error (MMSE) noise estimator that takes advantage of dual-channel noisy observations to avoid the use of a clean speech model while keeping a simple formulation. The parameters of this estimator are obtained through the unscented transform (UT), which is able to compute better quality statistics in a more efficient way than through classical vector Taylor series (VTS) linearization. For evaluation, speech enhancement on a dual-microphone smartphone in close-talk conditions is considered, which is a particular application of interest. Results show the superiority of our proposal with respect to other single-and dual-channel noise estimation methods in terms of different measures such as estimation accuracy as well as on the enhanced speech signal, i.e., speech quality and intelligibility.","PeriodicalId":383018,"journal":{"name":"2018 41st International Conference on Telecommunications and Signal Processing (TSP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132370247","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}

Unlike the prevalent methods for image security like steganography, the proposed scheme does not tamper with the medical images and ensures no loss of medical information. The digital unique ID is obtained by strategically combination of local features extracted from MRI image in Singular Value Decomposition (SVD) domain and patient's information. For authentication of medical image, the patient's information can be recovered from generated unique ID without any loss only after access of the particular unique ID. The proposed method has been tested on the publicly accessible dataset of medical MRI images and promising results were observed for solving the security issues of medical MRI images. Therefore the proposed method can be implemented in the field of tele-medicine and can be applied in areas where accurate and loss-less verification is a must as this may have great relevance when human health is concerned.","PeriodicalId":383018,"journal":{"name":"2018 41st International Conference on Telecommunications and Signal Processing (TSP)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131709503","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}
