This book discusses  response feature technology and its applications to modeling, optimization, and computer-aided design of high-frequency structures including antenna and microwave components. By exploring the specific structure of the system outputs, feature-based approaches  facilitate simulation-driven design procedures, both in terms of improving their computational efficiency and reliability. These benefits are associated with the weakly nonlinear relationship between feature point coordinates and design variables, which—in the context of optimization—leads to...

In an effort to overcome the spectral efficiency loss and high latency by half-duplex (HD), full-duplex (FD) has attracted extensive attention in industry and academia. With signal transmitted and received simultaneously over the same frequency, FD can approximately double the SE over HD. More than that, by enabling the capability of simultaneous transmission-and-reception for communication nodes, full duplex (FD) is a key enabler for many 5G techniques, including but not limited to integrated sensing and communication, low-latency relaying, concurrent bi-directional uplink and downlink...

This book covers the most recent, advanced methods for designing mixed-signal integrated circuits, for radiation-hardened sensor readouts (capacitive) and frequency synthesizers (quadrature, digitally controlled oscillators and all-digital PLL etc.). The authors discuss the ionizing radiation sources, complex failure mechanisms as well as several mitigation strategies for avoiding such failures. Readers will benefit from an introduction to the essential theory and fundamentals of ionizing radiation and time-based signal processing, with the details of the implementation of several...

This book introduces the fundamentals of physical layer security (PLS) and demonstrates how a variety of PLS techniques can be applied to improve the security of wireless communication systems. In particular, this book covers three security aspects of wireless communications. It includes secrecy, i.e., preventing eavesdroppers from intercepting information from transmitted wireless signals, covertness, i.e., hiding the transmitted signals themselves from malicious wardens and authentication, i.e., authenticating the identities of communicating entities. 

When discussing the secrecy...

This book studies the intersection between cryptography and AI, highlighting the significant cross-impact and potential between the two technologies. The authors first study the individual ecosystems of cryptography and AI to show the omnipresence of each technology in the ecosystem of the other one. Next, they show how these technologies have come together in collaborative or adversarial ways. In the next section, the authors highlight the coevolution being formed between cryptography and AI. Throughout the book, the authors use evidence from state-of-the-art research to look ahead at the...

These next generation standardization activities and related technical discussions are getting more and more interesting because advanced communication theories are consistently proposed, studied, discussed, and finally adopted as one of major technologies in standardization activities; e.g., millimeter-wave wireless communications, massive multiple-input-multiple-output (MIMO) wireless systems and precoding, device-to-device networking. This book introduces cutting-edge technological topics in future mobile cellular and wireless access standardization. With a solid understanding about the...
