Enhanced physical layer security by OFDM signal transmission in fractional Fourier domains
(Institute of Electrical and Electronics Engineers, 2015)
The main idea of physical layer security for wireless communications is making the transmitted signal as meaningless for eavesdroppers. It can be achieved by signal processing techniques. In this study, fractional Fourier ...
Short paper: Secure multi-user transmission using CoMP directional modulation
(Institute of Electrical and Electronics Engineers, 2015)
Directional Modulation is a recently developed multi-antenna technique for secure transmission. It allows to transmit signals in desired directions while distorting the signal in the other directions. To secure the ...
A microcontroller-based wireless multichannel neural data transmission system
(Institute of Electrical and Electronics Engineers, 2017)
Chronically implantable microelectrode arrays enable multichannel electrophysiological recordings from the mammalian brains during behavioral experiments. Wireless data transmission systems combined with the microelectrode ...
N-continuous OFDM with CP alignment
(Institute of Electrical and Electronics Engineers, 2015)
In this paper, we propose an out-of-band (OOB) reduction method which incorporates with multipath channel and N-continuous OFDM structure. By exploiting the inevitable guard periods between OFDM symbols, i.e., cyclic prefix ...
Iterative tap pursuit for channel shortening equalizer design
(Institute of Electrical and Electronics Engineers Inc., 2018)
In this work, an iterative tap pursuit algorithm for designing channel shortening equalizers is proposed. Similar to pursuit algorithms, a residual vector is initialized with a desired target impulse response, which is ...
The impact of the use of sacubitril/valsartan on clinical and echocardiographic parameters in heart failure patients
(Wiley, 2019)
Background: Sacubitril/valsartan is a guideline-recommended alternative drug to Angiotensin-Converting enzyme inhibitors (ACEIs) or Angiotensin II Receptor Blockers (ARBs) to reduce morbidity and mortality in patients with ...
Waveform design principles for 5G and beyond
(Institute of Electrical and Electronics Engineers Inc., 2016)
Various emerging applications in future wireless networks require rethinking the access techniques not only from the capacity perspective but also satisfying a wide variety of requirements under the same framework. Traditional ...
Channel independent physical layer security
(Institute of Electrical and Electronics Engineers Inc., 2016)
Security is one of the key requirements of wireless communication systems. By exploiting the broadcast nature of wireless medium, a malicious user might attempt to mislead the legitimate nodes, intercept the communication ...
Static cyclic prefix alignment for OFDM-based waveforms
(Institute of Electrical and Electronics Engineers Inc., 2016)
The cyclic prefix (CP) alignment is an appealing technique for achieving multiple goals such as peak-to-average power ratio (PAPR) reduction, out-of-band (OOB) leakage suppression, and physical layer (PHY) security. It ...
Reliable listen-before-talk mechanism for medical implant communication systems
(Institute of Electrical and Electronics Engineers Inc., 2016)
Health care applications of wireless communication have been finding places dramatically. One of these applications is communication of implantable medical devices (IMD)s. It is expected that the number of IMDs will increase ...
