Blind numerology identification for mixed numerologies
(IEEE - Institute of Electrical and Electronics Engineers, Inc, 2021)
5G New Radio (NR) introduces new flexibility that different numerologies can be selected to meet the requirements of a wide variety of services. For this new structure, blind numerology identification can increase system ...
Energy-efficient resource allocation for 5G cognitive radio NOMA using game theory
(IEEE - Institute of Electrical and Electronics Engineers, Inc, 2021)
Cognitive radio non-orthogonal multiple access (CR-NOMA) networks promise improved spectrum utilization and capacity in 5G networks. In this work, we aim to investigate efficient power allocation for the secondary users ...
Reconfigurable intelligent surface (RIS): Eigenvalue decomposition-based separate channel estimation
(Institute of Electrical and Electronics Engineers Inc., 2021)
Reconfigurable intelligent surface (RIS) has recently drawn significant attention in wireless communication technologies. However, identifying, modeling, and estimating the RIS channel in multiple-input multiple-output ...
Channel modeling for 5G and beyond
(Institution of Engineering and Technology, 2020)
The wide variety in enabling technologies, operating scenarios, environments, and use cases required for the fifth generation (5G) communication system and beyond 5G (B5G) entails the availability of descriptive channel ...
Generalized and flexible modulation options
(Institution of Engineering and Technology, 2020)
Flexibility support is critical for fifth generation (5G) and beyond radio access technologies (RATs) to meet diverse applications, channel conditions, and user requirements. Besides the flexible waveform design discussed ...
Foreword
(Institution of Engineering and Technology, 2020)
The most critical difference of the fifth generation (5G) mobile communication technology compared to previous generations is its ability to support a wide variety of services. In other words, the 5G technology is all about ...
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 ...
