The number and significance of wireless sensing use-cases highlight the importance of a framework to acquire information on the radio environment. This chapter introduces such a framework, goes over relevant technologies, and provides a case study for environment sensing. The most well-studied area of radio environment map (REM) is perhaps the radio frequency map construction. The chapter provides this as an example for the working of the REM architecture. The generalized radio environment monitoring framework enables information gathering and radio and physical environment awareness, behaving as an independent entity capable of feeding information to other entities.Öğe Wireless channel and interference(Wiley, 2021) Kihero, Abuu Bakari; Tusha, Armed; Arslan, HüseyinThis chapter focuses on various critical aspects of wireless channel starting with explanation of the dominant propagation phenomena and their resultant effects on the system. It then touches upon mechanisms employed for empirical measurement of these channel effects, as well as techniques commonly used to represent them in a way that is useful for system design (i.e. channel modeling). The features of interference caused by wireless channel are grouped considering the fading characteristics of the medium, such as large-scale and small-scale fading. In order to enable the control of wireless environment, several approaches have been proposed and discussed in the literature. The chapter also focuses on two promising techniques: reconfigurable antenna and reconfigurable intelligent surface. Finally, it explains basic channel emulation techniques which are used to reproduce various propagation effects in the laboratory environment for system testing.Öğe RF impairments(Wiley, 2021) Arslan, HüseyinThis chapter discusses baseband equivalent models for various radio frequency impairments. It explains the impacts of these impairments on the system performance through various tools and measurements. The transmitted signal, that goes through the in-phase and quadrature-phase vector modulator, experiences several levels of signal distortion due to imperfection in the modulator. These distortions can greatly affect the performance of the received signal and the overall system performance. Nonlinear power amplifiers can achieve better efficiencies with poor linearity in their responses. The nonlinearity causes several problems like amplitude and phase distortion and adjacent channel regrowth. Frequency offset and phase noise impairments can destroy the orthogonality in orthogonal frequency division multiplexing leading to inter-carrier interference. Similarly, timing jitter and sample clock error can destroy the orthogonality in raised cosine pulse-shaped single-carrier systems, causing inter-symbol interference.Öğe Blind signal analysis(Wiley, 2021) Aygül, Mehmet Ali; Naeem, Ahmed; Arslan, HüseyinBlind signal analysis (BSA) plays an essential role in wireless communication when the receiver does not know most or all of the received signal parameters. This chapter provides an in-depth understanding of BSA with laboratory implementation for different applications. The usage of BSA varies depending on the applications and its model. The chapter reviews spectrum sensing, parameter estimation and signal identification, radio environment map, equalization, modulation identification, and multi-carrier parameter estimation in the context of BSA. It presents preliminary information for machine learning (ML) and provides applications of the multidisciplinary domain (BSA and ML) including signal and interference identification, multi-RF impairments identification, channel modeling and estimation, and spectrum prediction with their future directions and challenges. Although the ML paradigm wants to fulfill BSA requirements, there are still some major problems in applying this paradigm practically. The chapter presents a list of these challenges.Öğe Analysis of single-carrier communication systems(Wiley, 2021) Arslan, HüseyinThis chapter discusses some of the fundamental concepts related to single-carrier communication. It focuses on the practical aspects of the implementation, analysis, and performance measurement of single-carrier systems. The chapter describes a single-carrier communication system in additive white Gaussian noise channel. Sample clock error is one of the most critical impairments in the model and the one that is described next (flat fading multipath channel). When the transmitted signal passes through a multipath radio channel where the relative path delays are on the order of a symbol period or more, then images of different symbols arrive at the same time. The dispersive channel, which is often referred as frequency selective channel, can be modeled as a linear, finite impulse response filter. A similar system model that is used for narrowband systems in dispersive channels can be used for direct spread code division multiple access systems.Öğe 5G and beyond networks(Elsevier, 2021) Ruiz, Silvia; Ahmadi, Hamed; Gardaševi?, Gordana; Haddad, Yoram; Katzis, Konstantinos; Grazioso, Paolo; Petrini, Valeria; Reichman, Arie; Özdemir, Mehmet Kemal; Velez, Fernando; Paulo, Rui; Fortes, Sergio; Correia, Luis M.; Rouzbehani, Behnam; Barahman, Mojgan; Deruyck, Margot; Mignardi, Silvia; Nasr, Karim; Zhang, HaibinThis chapter investigates the Network Layer aspects that will characterize the merger of the cellular paradigm and the IoT architectures, in the context of the evolution towards 5G-and-beyond, including some promising emerging services as Unmanned Aerial Vehicles or Base Stations, and V2X communications.Öğe Multiple accessing, multi-numerology, hybrid waveforms(Wiley, 2021) Şahin, Mehmet Mert; Arslan, HüseyinThis 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 orthogonal frames in order to manage the interference between the users. The concept of non-orthogonal multiple access has been proposed to overcome the limitation of orthogonal resources. The chapter also provides a comparison between random access schemes. It presents insight into which specific scheduled or random access technique to apply. The chapter emphasizes the real wireless system development problem of how to design a multiuser system depending on the system requirements, traffic characteristics of users in the network, performance measurements, channel characteristics, and other interfering systems operating in the same bandwidth. It examines a novel concept called radar-sensing and communication convergence by the perspective of the hybrid waveforms concept.Öğe Performance metrics and measurements(Wiley, 2021) Arslan, HüseyinThis 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 used in adaptive systems. In addition to various measurements to identify the quality of the signal, visual graphs are also very useful to get insight on impairments and other disturbances impacting the signal. Constellation diagram can be obtained by plotting the imaginary versus the real part of the complex signal. Signal intelligence and generic signal analysis could be extremely important for testing software-defined radio transmitter, especially in doing government regulation, observing an operating network, qualification of a product, and to some extent R&D verification. Reference signal received power measurement, normally expressed in dBm, is utilized mainly to make ranking among different candidate cells in accordance with their signal strength.
