Experimentations involving two well-known algorithms for Angle Of Arrival estimation, conventional beamforming and baseline interferometry, have been conducted. The realized RF front end and National Instruments hardware with LabVIEW programming tool have been used for RF signal conditioning and digital signal processing respectively. The testbed setup and the front end realization steps are explained. The experimental results of the two algorithms are given for test signals of arbitrary frequencies and angles of arrival to demonstrate the utility of the RF front end and the successful implementation of both algorithms.","PeriodicalId":371206,"journal":{"name":"2017 Seminar on Detection Systems Architectures and Technologies (DAT)","volume":"5 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":"130809527","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 new approach for PAPR reduction over powerline communication (PLC) based on the combination of μ-law companding and a novel clipping function. The new clipping process is introduced to remove out the impulsive noise generated over the electric wires and at the same time it is used to reduce the PAPR introduced through the OFDM based PLC. Then, a μ-law companding function is combined with the clipping function to add more robustness against impulsive noise and PAPR. Simulation results show the significant reduction in PAPR and bit error rate (BER) achieved using the proposed technique.","PeriodicalId":371206,"journal":{"name":"2017 Seminar on Detection Systems Architectures and Technologies (DAT)","volume":"7 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":"133116879","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}

These algorithms are the Second-Order Difference Array (SODA), CORRelative (CORR) interferometer, and Phase Rotation Algorithm (PRA). In the second part, an efficient Field Programmable Gate Array (FPGA) implementation of PRA, is proposed and compared to the implementation of SODA and CORR algorithms.

The MTM structures are designed to have a resonant frequency around 2.88GHz and achieve Negative values of Permeability and Permittivity within the operating frequency ranges. S-parameter and retrieved effective value for MTM structures, the return loss, bandwidth and radiation pattern for monopole antenna with MTMs are all simulated using CST software. The simulated data show that the proposed MTM can produce a relatively low resonant frequency (dual band) with reduced antenna dimensions without external matching network. It has been remarked that the bandwidth of the proposed monopole antenna is increased when associated with the metamaterial structure.","PeriodicalId":371206,"journal":{"name":"2017 Seminar on Detection Systems Architectures and Technologies (DAT)","volume":"15 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":"129026585","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 approach benefits from the modulation within radar pulses to extract the components through pulse compression. A typical radar system employing coherent quadrature demodulation and pulse compression implements these two steps separately. When I/Q components are extracted at the RF or IF stage, high rate and costly ADCs are needed along with costly digital hardware. The joint I/Q demodulation/pulse compression approach investigated operates at baseband, reducing therefore digitization rate and cost of the associated digital hardware. Furthermore, since the demodulation is combined with pulse compression, the resulting architecture is less complex which is suitable for low cost, less demanding radar applications. The considered simulation scenarios that validate the efficiency of the proposed approach and the obtained results are presented and discussed.","PeriodicalId":371206,"journal":{"name":"2017 Seminar on Detection Systems Architectures and Technologies (DAT)","volume":"48 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":"131568787","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 overcome these problems, we present in this work the designing of an ultra-wideband matrix with multi-layer features for two different topologies. The first type of conductors of this matrix was designed with a lozenge shape, and the second type designed with an elliptical topology which allows minimizing the losses and ensures a good performance compared to the first type of conductors.","PeriodicalId":371206,"journal":{"name":"2017 Seminar on Detection Systems Architectures and Technologies (DAT)","volume":"186 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":"132127384","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 can bring substantial improvements over conventional point-to-point MIMO by focusing energy into ever smaller regions of space to bring huge improvements in throughput and radiated energy efficiency. However, increasing the number of antennae at BS will automatically leads to additional energy consumption due to RF chains and signal processing circuit. In this study, we attempt to exploit Artificial Bee Colony (ABC) algorithm in optimizing the energy efficiency by finding the suitable combination (antennae size, active users) that maximize the energy efficiency.
