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, ...
Multiple elements MIMO antenna system with broadband operation for 5th generation smart phones
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2022)
In this work, a simple, low-cost, dual wideband sub6GHz Multiple Input Multiple Output (MIMO) antenna system for a smart phone is presented. The antenna system is fabricated using inexpensive and commercially easily available ...
Cyclic feature suppression for physical layer security
(Elsevier Sciences Bv, 2017)
Cyclic prefix (CP) deploying techniques such as orthogonal frequency division multiplexing (OFDM) and single carrier frequency domain equalization (SC-FDE) offer considerable advantages in terms of equalizing time dispersive ...
VLCnet: Deep learning based end-to-end visible light communication system
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2020)
Visible light communication is a popular research area where proposed communication methods must satisfy the lighting related requirements as well. Suggested VLC modules should not only improve communication quality such ...

Space-variant blur kernel estimation and image deblurring through kernel clustering
(Elsevier B.V., 2019)
This paper presents a space-variant blur kernel estimation and image deblurring framework. For space-variant blur kernel estimation, the input image is divided into small patches, and for each patch, the blur kernel is ...
Light field extraction from a conventional camera
(Elsevier B.V., 2022)
This paper presents a single-shot light field (LF) acquisition method using a conventional camera. The proposed method does not require any modification in the camera design and instead involves an offline calibration ...
A three-mask process for fabricating vacuum-sealed capacitive micromachined ultrasonic transducers using anodic bonding
(Institute of Electrical and Electronics Engineers, 2015)
This paper introduces a simplified fabrication method for vacuum-sealed capacitive micromachined ultrasonic transducer (CMUT) arrays using anodic bonding. Anodic bonding provides the established advantages of wafer-bonding-based ...
Extending depth of field and dynamic range from differently focused and exposed images
(Springer, 2016)
Focus stacking and high dynamic range (HDR) imaging are two paradigms of computational photography. Focus stacking aims to produce an image with greater depth of field (DOF) from a set of images taken with different focus ...
Emulation techniques for small scale fading aspects by using reverberation chamber
(Ieee-Inst Electrical Electronics Engineers Inc, 2019)
Reverberation chambers (RVCs) are used to provide an efficient and reliable testbed for emulating the wireless channel effects in the laboratory environment. In the literature, various techniques have been studied to enrich ...
