Semiconductor-based devices with increased reliability, low cost, unusual lightness, small size, and minimal service have become an important part of our daily lives. It is difficult to imagine life without electronic vehicles, TVs, computers, smartphones, medical networks, and global e-commerce. As this book argues, semiconductors are the main “driving force” behind economic strength, national security, and resilience in times of crisis. However, novel types of semiconductors are needed in order to support ever-growing scaling demands today. Developing semiconductors with desired properties, such as tolerance to radiation, for instance, is of crucial importance. InAs-InP solid solutions present an example of such materials used for cutting-edge electronic technologies. Packed with diagrams and accompanying detailed computations, this book provides a comprehensive coverage of InAs1-xPx solid solutions, from the production of single bulk crystals and layers to the thorough study of their properties and to their inexhaustible application potential in electronics.

Build and operate multi-GNSS and multi-frequency receivers with state-of-the-art techniques using this up-to-date, thorough, and easy-to-follow text. Covering both theory and practise, and complemented by MATLAB code and digital samples with which to test it, this package is a powerful learning tool for students, engineers, and researchers everywhere. Suggestions of hardware equipment allow you to get to work straight away and to create your own samples. Concisely but clearly explaining all the fundamental concepts in one place, this is also a perfect resource for readers seeking an introduction to the topic. Software-defined radios (SDRs) brought an unprecedented degree of flexibility to the design of the receivers that support radio navigation. Previously, such design work had been the domain of a handful of hardware manufacturers whose schemes were implemented in hardware. This hardware provided a limited set of outputs and virtually no access to the internal states and data processing. SDRs allowed customization that simply was not possible using mass-produced receiver sets.

What is an Artificial Intelligence (AI)-enabled drone and what can it do? Are AI-enabled drones better than human-controlled drones? This book will answer these questions and more, and empower you to develop your own AI-enabled drone. You'll progress from a list of specifications and requirements, in small and iterative steps, which will then lead to the development of Unified Modeling Language (UML) diagrams based in part to the standards established by for the Robotic Operating System (ROS). The ROS architecture has been used to develop land-based drones. This will serve as a reference model for the software architecture of unmanned systems.

This book aims to cover a new emerging need in designing digital phase shifter for modern communication systems. With the advancement of new generation mobile communication systems, directed beams of antenna arrays save a substantial amount of power as well as improve the communication quality. In this regard, beam-forming circuits, such as digital phase shifters (DPS) constitute essential parts of the antenna array systems. Therefore, this book is devoted to the design of digital phase shifters for various communications systems. Nowadays, phase array systems demand compact phase shifters suitable for chip implementation with wide phase-range and broad frequency band. For each phase shifter topology introduced in this book, the reader is furnished with explicit design equations to construct the circuit under consideration. Furthermore, design equations are programmed using MATLAB to assess the electrical performance of the phase shifters with ideal and lossy components. MATLAB design programs are given at the and of each chapter as appendices and provided as soft copy on the web page of the book.
