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 ...
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. ...
Multiple accessing, multi-numerology, hybrid waveforms
(Wiley, 2021)
This chapter focuses on the issue of how to intelligently share the resources in a hyperspace whose dimensions are time, frequency, space, beam, and code. Most of the wireless communication standards prefer to design ...
Performance metrics and measurements
(Wiley, 2021)
This chapter discusses various metrics and measurement techniques discussed to inspect the communication system architecture and its performance. Signal quality estimation is by far the most important measure that can be ...
Radio environment monitoring
(Wiley, 2021)
The high number of wireless devices available and the inherent relationship between electromagnetic wave propagation and the physical environment have made these devices and their network architectures ideal sources of ...
