Experimental characterization of in vivo radio channel at MICS and ISM Bands
(Electromagnetics Academy, 2015)
This paper presents an experimental study for the propagation losses and wave attenuation inside human body for implanted antenna at different body organs. The experimental study discusses the commonly used frequency bands: ...
Waveform designs for cognitive radio and dynamic spectrum access applications
(Springer Singapore, 2019)
Cognitive radio and dynamic spectrum access systems are effective ways of using radio spectrum which is a scarce source. Cognitive radio applications changed the paradigm for the wireless communications systems in the past ...
Space-varying blur kernel estimation and image deblurring
(SPIE, 2014)
In recent years, we have seen highly successful blind image deblurring algorithms that can even handle large motion blurs. Most of these algorithms assume that the entire image is blurred with a single blur kernel. This ...
Super-resolution restoration of motion blurred images
(SPIE, 2014)
In this paper, we investigate super-resolution image restoration from multiple images, which are possibly degraded with large motion blur. The blur kernel for each input image is separately estimated. This is unlike many ...
Frequency division multiplexed imaging: A Texas Instruments DMD implementation
(SPIE-Int Soc Optical Engineering SPIE, 2014)
Recently we proposed frequency division multiplexed imaging (FDMI), which allows capturing multiple images in a single shot through spatial modulation and frequency domain filtering. This is achieved by spatially modulating ...
User association for enhancing physical layer security in heterogeneous network
(Springer, 2019)
In this work, a fair user association scheme is proposed for heterogeneous networks aiming to enhance physical layer security (PLS). More specifically, the user association problem is formulated as a Nash bargaining problem ...
Quantum laboratory setup for future wireless communication systems
(American Institute of Physics Inc., 2019)
Fifth generation of wireless communication envisages a diverse network that imposes stringent requirements regarding capacity, reliability, security, latency and seamless connectivity. These lofty goals have driven researchers ...
OFDM signal analysis and performance evaluation
(Wiley, 2021)
Orthogonal frequency division multiplexing (OFDM) is the most popular multi-carrier waveform that is used to achieve high spectral efficiencies. This chapter provides an in-depth understanding of OFDM as well as its ...
Simulating a communication system
(Wiley, 2021)
This chapter looks at the basics of simulation of communication systems, covering topics such as strategy, modeling, general methodology, link and network-level categorization, error sources, performance evaluation, and ...
Multidimensional signal analysis
(Wiley, 2021)
This chapter discusses signal characteristics in multiple domains, leading to the concept of multidimensional signal analysis. Multidimensional signal analysis is referred for analyzing the received radio signal from ...
