Thus, this work which conducted a Maximum Ratio Combining (MRC) scalable CP-OFDM modulation and was based on a measurement at 60 GHz is basically proposed for New Radio (NR)-5G system. Measurements are taken between three buildings under a non-line-of-sight (NLOS) scenario for a path length of 183 m. The measured impulse response has been used to evaluate the performance of NR-5G in terms of the BER. An MRC combiner is also used to maximize the instantaneous SNR at the output of Multi-Input Multi-Output (MIMO) schemes. The expected results are verified by an outdoor mm-wave link (60 GHz) under NLOS conditions for radio access transmission, where high transmission efficiency and data rates could be achieved. Therefore, these results would motivate the use of MRC-CP-OFDM waveform for mobile communication 5G-NR in the downlink.","PeriodicalId":269759,"journal":{"name":"2021 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET)","volume":"303 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122013583","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}

Noncontact monitoring processes will provide an advantage in covering a large area operation. The radar system is potentially applied as a noncontact sensor. However, small displacement detection requires high resolution referring to the range resolution perspective. Detecting a small displacement on a millimeter to centimeter scale requires a very wide bandwidth. The main information to be obtained from small displacement detection is the distance of the target and the size of the small displacement. Frequency modulation continuous wave (FMCW) is a radar system that has been widely used in various fields. In this paper, a small displacement detection method is proposed by developing the detection capabilities of the FMCW radar. The ability to detect distance using beat frequency identification is maintained and phase detection is elaborated to detect small displacement without having to increase bandwidth. The experimental modeling of proposed FMCW using a vector network analyzer (VNA) was conducted in this study. The results show that the proposed FMCW system using VNA has the ability to detect small displacement with average phase shift of 0.41 radians for a 2 mm shift in the direction close to the target and 0.44 radians for the direction away from the target.","PeriodicalId":269759,"journal":{"name":"2021 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET)","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122516754","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 speed quality of the DC motor needs to be guaranteed from interference and uncertainty. Although the components of DC motor such as electronics and mechanics can develop plant model, its degradation and sensor noise may provide uncertainty. In addition, disturbance from the environment and overload can interfere with the performance of a DC motor. This research aims to apply the mixed sensitivity synthesis method of H-infinity robust control for optimization on speed control of DC motor model to deal with uncertainty. The mechatronics component principle model is calculated by mixed-sensitivity synthesis procedure for constructing the H-infinity controller K. The simulation and analysis of the proposed method showed that the circumstances on robust criteria and H-infinity norm are successfully satisfied singular values. The optimization controller design is robustly stable due to limited perturbations assessment, particularly as noise sensor simulation. The proposed design also provided better overshoot and smother signals.","PeriodicalId":269759,"journal":{"name":"2021 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115964448","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 design starts by implementing a single element of Printed Circular Disc Monopole (PCDM) antenna on a 1.6 mm thick FR-4 substrate having a relative permittivity of 4.4. A parametric analysis, as well as slots insertion, are performed based on “Finite Difference Time Domain Analysis (FDTD)” to improve the structure performance related to the operating bandwidth. Concerning the MIMO antenna structure, a four-element configuration is investigated. Over the intended frequency band, the isolation is greater than 15 dB. The “Envelope Correlation Coefficient (ECC)”, “Diversity Gain (DG)”, and “Channel Capacity Loss (CCL)” have all been shown to improve diversity performance and are determined to be within acceptable limits. A network analyzer is used to measure the antenna structure once it is constructed. In terms of scattering characteristics and spectral efficiency, the measured and simulated are in good agreement.","PeriodicalId":269759,"journal":{"name":"2021 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET)","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117079581","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}

Rectangular Antenna Arrays guarantee good performances, both in azimuth and elevation in the Direction of arrival (DoA) estimation. This paper studies the eight antenna rectangular array topology, called URA8. Historically, MUSIC has been the most used algorithm on this type of array. Unfortunately in HAAT real-time applications, where it is essential to have a fast response from the DoA Locator, MUSIC, due to its high computational complexity in the peak searching over the pseudo-spectrum, may be inadequate for the scope. This paper proposes an innovative approach to reduce the complexity of this peak-searching phase: instead of only one peak-search over the complete azimuth-elevation hemisphere, we propose a two step search, the first with a reduced resolution and the latter with a fine resolution inside a proper confidence region, found in the first step. The proposed method ensures a good trade-off between computational complexity and detection performances: it turns out to approximately 6 times faster than the classic MUSIC, maintaining the same precision.","PeriodicalId":269759,"journal":{"name":"2021 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125142158","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}
