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 ...
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 ...

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 ...
Carrier and time synchronization
(Wiley, 2021)
Mismatch in both time and frequency between communication sides is inevitable, and the receiver must be synchronized with the transmitter; otherwise, the performance of the system is degraded severely if it operates at ...
Hands-on wireless communication experience
(Wiley, 2021)
This chapter introduces a wireless communication systems lab that will provide readers with the experience to design, test, and simulate wireless systems (along with wireless circuits) using modern instrumentation and ...
Digital modulation and pulse shaping
(Wiley, 2021)
Depending on the channel conditions, radio frequency hardware cost and properties, allowed complexity, required data rate, available bandwidth, and desired levels of performance some will provide a better fit than others. ...
