In-Band Full-Duplex Wireless Systems Handbook available in PDF, EPUB and Kindle. Many wireless systems could benefit from the ability to transmit and receive on the same frequency at the same time, which is known as In-Band Full-Duplex (IBFD). This technology could lead to enhanced spectral efficiency for future wireless networks, such as fifth-generation New Radio (5G NR) and beyond, and could enable capabilities and applications that were previously considered impossible, such as IBFD with phased array systems. In this exciting new book, experts from industry, academic, and federal research institutions discuss the various approaches that can be taken to suppress the inherent self-interference that is generated in IBFD systems. Both static and adaptive techniques that span across the propagation, analog and digital domains are presented. Details and measured results that encompass high-isolation antenna designs, RF, and photonic cancellation as well as signal processing approaches, which include beamforming and linear/non-linear equalization are detailed. Throughout this book, state-of-the-art IBFD systems that utilize these technologies will be provided as practical examples for various applications. Expert IBFD perspectives from multiple research organizations and companies, which would provide readers with the most accurate state-of-the-art approaches. This is the first book that dives into both the techniques that make IBFD systems possible as well as several different applications that use IBFD technology.

Download and read online ebook Full-Duplex Wireless Communications Systems write by Tho Le-Ngoc. This book was released on 2017-07-02. Full-Duplex Wireless Communications Systems available in PDF, EPUB and Kindle. This book introduces the development of self-interference (SI)-cancellation techniques for full-duplex wireless communication systems. The authors rely on estimation theory and signal processing to develop SI-cancellation algorithms by generating an estimate of the received SI and subtracting it from the received signal. The authors also cover two new SI-cancellation methods using the new concept of active signal injection (ASI) for full-duplex MIMO-OFDM systems. The ASI approach adds an appropriate cancelling signal to each transmitted signal such that the combined signals from transmit antennas attenuate the SI at the receive antennas. The authors illustrate that the SI-pre-cancelling signal does not affect the data-bearing signal. This book is for researchers and professionals working in wireless communications and engineers willing to understand the challenges of deploying full-duplex and practical solutions to implement a full-duplex system. Advanced-level students in electrical engineering and computer science studying wireless communications will also find this book useful as a secondary textbook.

Download and read online ebook An Introduction to Optical Wireless Mobile Communication write by Harald Haas. This book was released on 2021-09-30. An Introduction to Optical Wireless Mobile Communication available in PDF, EPUB and Kindle. The use of the optical spectrum for wireless communications has gained significant interest in recent years. Applications range from low-rate simplex transmission links using existing embedded CMOS cameras in smartphones, referred to as optical camera communications (OCC), mobile light fidelity (LiFi) networking in homes, offices, urban and sub-sea environments to free-space gigabit interconnects in data centers and point-to-point long-range wireless backhaul links outdoors and in space. This exciting book focuses on the use of optical wireless communications (OWC) for mobile use cases. The book discusses existing conventional radio frequency (RF)-based wireless access technology and presents the challenges that can impact the requirements of the future wave of new wireless services in the context of artificial intelligence (AI) driven autonomous systems and machine-type communications. The relationship between visible light communications (VLC) and light fidelity (LiFi), is explored, and the major advantages of VLC and LiFi such as security and data density, and discuss existing research challenges are also introduced. Channel modeling techniques are provided for mobile multiuser scenarios, and will introduce key building blocks to achieve LiFi cellular networks achieving orders of magnitude improvements of area spectral efficiency compared to state-of-the-art. Challenges that arise from moving from a static point-to-point visible light link to a LiFi network that is capable of serving hundreds of mobile and fixed nodes are discussed. An overview of recent standardization activities and the commercialization challenges of this disruptive technology is also provided.

Download and read online ebook Wi-Fi 6: Protocol and Network write by Sundar Gandhi Sankaran. This book was released on 2021-08-31. Wi-Fi 6: Protocol and Network available in PDF, EPUB and Kindle. With more than 15 billion Wi-Fi enabled devices, Wi-Fi has proven itself as a technology that has successfully evolved over the past 25 years. The need for high-speed connectivity is growing, as Wi-Fi has evolved into a fundamental utility that is expected to be available everywhere. This comprehensive resource covers six generations of Wi-Fi standards including protocol, implementation, and network deployment for both residential and enterprise environments. It will provide readers with a new understanding of how to approach and debug basic Wi-Fi problems, and will grant those wondering whether to pick 5G or Wi-Fi 6 for their product the clarity needed to make an informed decision. Readers will find in-depth coverage of Wi-Fi encryption and authentication methods, including explorations of recently uncovered security vulnerabilities and how to fix them. This book also provides detailed information on the implementation of Wi-Fi, including common regulatory and certification requirements, as well its associated challenges. This book also provides direction on the placement of Wi-Fi access points in indoor locations. It introduces the most recent Wi-Fi 6E certification, which defines requirements for devices operating on the newly opened 6 GHz band.
