IQI mitigation for narrowband iot systems with OFDM-IM
(Institute of Electrical and Electronics Engineers Inc., 2018)
The crucial aim for 5G narrowband Internet of Things (NB-IoT) is to support massive connectivity with wide coverage area, low power consumption, low hardware complexity, and low data rate. Direct conversion receiver (DCR) ...
Randomized beamforming with generalized selection transmission for security enhancement in MISO wiretap channels
(IEEE-Inst Electrical Electronics Engineers Inc, 2018)
Transmit beamforming (TBF) has been proposed as an effective approach to enhance the security performance of multiple-input single-output (MISO) wiretap channels. However, this secrecy enhancement comes at some expenses, ...
Light field super resolution through controlled micro-shifts of light field sensor
(Elsevier Science Bv, 2018)
Light field cameras enable new capabilities, such as post-capture refocusing and aperture control, through capturing directional and spatial distribution of light rays in space. Micro-lens array based light field camera ...
Joint phy/mac layer security design using arq with mrc and null-space independent papr-aware artificial noise in siso systems
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2018)
Automatic-repeat-request (ARQ) as a MAC layer mechanism and artificial noise (AN) as a physical layer mechanism along with the help of maximal ratio combining (MRC), are jointly designed to achieve secrecy. Basically, a ...
OFDM with index modulation for asynchronous mMTC networks
(MDPI, 2018)
One of the critical missions for next-generation wireless communication systems is to fulfill the high demand for massive Machine-Type Communications (mMTC). In mMTC systems, a sporadic transmission is performed between ...
Deep learning- and word embedding-based heterogeneous classifier ensembles for text classification
(Wiley-Hindawi, 2018)
The use of ensemble learning, deep learning, and effective document representation methods is currently some of the most common trends to improve the overall accuracy of a text classification/categorization system. Ensemble ...
Complications of 2-level dynamic stabilization: A correlative clinical and radiological analysis at two-year follow-up on 103 patients
(Turkish Neurosurgical Society, 2018)
AIM: To investigate the postoperative complications, such as screw loosening, screw breakage and adjacent segment disease (ASD), in patients who underwent surgery with 2-level dynamic stabilization systems. MATERIAL and ...
Mutual coupling compensation in transmitting arrays of thin wire antennas
(Applied Computational Electromagnetics Society (ACES), 2018)
This paper presents a numerical technique for the compensation of mutual coupling in transmitting arrays of thin wire antennas. The Method of Moments is used to compute the scattering parameters of the array. Using these ...
NOMA for multinumerology OFDM systems
(Wiley Hindawi, 2018)
Nonorthogonal multiple access (NOMA) is a promising technique which outperforms the traditional multiple access schemes in many aspects. It uses superposition coding (SC) to share the available resources among the users ...
Adaptive OFDM-IM for enhancing physical layer security and spectral efficiency of future wireless networks
(Hindawi Limited, 2018)
In this paper, we propose algorithms for enhancing physical layer security and spectral efficiency of Orthogonal Frequency Division Multiplexing (OFDM) with Index Modulation (IM) systems. Particularly, different activation ...
