For this purpose, a statistical millimeter wave (mmwave) MIMO channel simulator is carefully designed using state of the art channel models. At the mmwave frequencies, human/vehicular mobility around the mobile users may partially or completely block the communication link. This give rise to the consideration of new channel modeling parameter i.e. probability of a user to be in LOS dynamics. Higher line of sight (LOS) probabilities may increase the spatial correlation among the multiuser channels. Therefore, quantification of the spatial separation of users in different scenarios with distinct LOS probabilities is crucial and it is the subject of investigation of this paper. Additionally, the mutual orthogonality of channels by changing the number of base station (BS) antennas and inter antenna element distance (IED) have also been investigated. Analysis shows that LOS blockage of certain scenario has more impact at the degree of orthogonality among users as compared to the number of BS antennas and the spacing between the antenna elements.","PeriodicalId":284494,"journal":{"name":"2016 IEEE International Conference on Communication, Networks and Satellite (COMNETSAT)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114276944","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, the recent concepts of the massive MIMO systems (at centimeter wavelength frequencies) have shown that with higher spatial resolution of antenna arrays different users in the dense scenarios can be spatially separated. This in turn significantly reduces the signal processing efforts required for multiuser selection algorithms. On the other hand, recent measurements at millimeter wave frequencies show that multipath components only arrive from few angular directions leading to high spatial correlation between the paths and co-located users. This paper focus at the investigation of spatial separation among the users at the millimeter wave frequencies with fully digital linear zero-forcing transmit precoding considering various channel propagation parameters. Our analysis results convincingly give a proof that multiuser selection algorithms are still important for millimeter wave communication systems. Results also show that increased number of antenna elements does not give a major benefit to sum rate improvements as compared to the selection of correct number of users to be selected/scheduled.","PeriodicalId":284494,"journal":{"name":"2016 IEEE International Conference on Communication, Networks and Satellite (COMNETSAT)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126773954","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}

Finite-length buffer leads to lower delay quantities. We use relay selection scheme that improves the diversity gain in relay systems. Moreover, the packet loss rate is calculated.

It can provide an excellent orthogonality that is required by MIMO radar transmitter. Another privilege of using OFDM signal is the flexibility in subcarrier allocation when multiple MIMO radar user is considered. This paper analyzed about the comparison of radar detection accuracy, and resolution of four OFDM MIMO radar waveforms, i.e. Conventional OFDM-MIMO radar waveform, and three types of interleaved technique which are different in the way of allocating the subcarrier frequency when multi user scenario is concerned. Interleaved OFDM waveforms that will be compared here are the model introduced by Wiesbeck et al, Yoke et al, and random subcarrier interleaving. The transmitted OFDM signal is designed in such a way that the multiple transmitters will only radiate at the unique subcarriers. In this paper, MUSIC algorithm is used to obtain the target angle of arrival (AoA) information and virtual array is applied to improve radar ability in multi targets detection that usually limited by the number of receiver antennas. Radar performance comparison will be discussed in terms of the target range, velocity and the AoA resolution, including their accuracy and sidelobe levels.","PeriodicalId":284494,"journal":{"name":"2016 IEEE International Conference on Communication, Networks and Satellite (COMNETSAT)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126324864","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}

It maintains the advantages of Orthogonal Frequency Division Multiplexing (OFDM) from the fourth generation while avoiding its drawbacks; mainly, the requirements for a strict synchronization between transmitter and receiver. This convenience, however, increases computational complexity as UFMC employs filters to achieve this effect. While the performance of OFDM and UFMC against frequency synchronization error is investigated thoroughly, their performance to delay spread (aka multipath) and timing error has little attention. This paper contains the results of a simulation of UFMC against these communication impediments using MATLAB/Simulink™. In both schemes, the bit error rate is measured when the same number of bits modulated, transmitted, equalized, and demodulated. It is shown that UFMC outshines OFDM under both time and frequency synchronization errors and lags in performance under delay spread when delay spread is below a certain value. This is expected as OFDM preserves orthogonality due to the use of a cyclic prefix (CP). Also investigated in this study is the effect of increasing the filter length of UFMC in its performance. An increase in performance is evident for increasing lengths, but this convenience requires an increase in the number of sub-bands which complicates the system.","PeriodicalId":284494,"journal":{"name":"2016 IEEE International Conference on Communication, Networks and Satellite (COMNETSAT)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114874166","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}

Many approaches have been proposed with dominating machine learning and artificial intelligence techniques or its combination. High false positive rate is due to being more general while designing detection model. Rule-based network intrusion detection systems lack high false positive rate if any, because rules are tighter to individually known type of attack. Although anomaly-based network intrusion detection systems do not need prior knowledge of attack, it is still possible to imitate some rule-based specificity at certain level while designing detection model in order to reduce the false positive rate. The specificity being handled in this paper is the design of network intrusion detection system for TCP/IP network traffic. Then we propose a method to prepare quality clusters to build a network intrusion detection model. It has been surveyed that some research did not bring contribution to network based intrusion detection systems due to improperly preprocessed data especially during feature selection. In this paper, we propose an attribute selection method with basic TCP network features only.
