Anotácia knihy

Orthogonal Frequency Division Multiplexing (OFDM) has been the waveform of choice for most wireless communications systems in the past 25 years. This book addresses "the what comes next?" question by presenting the recently proposed waveform known as 'Orthogonal Time-Frequency-Space' (OTFS), which offers a better alternative for high mobility environments. The OTFS waveform is based on the idea that the mobile wireless channels can be effectively modelled in the delay-Doppler domain. The information is encoded in such domain, in order to exploit all the multipaths even they are affected by Doppler shifts present in high mobility environments. Delay-Doppler Communications: Priniciples and Applications covers the fundamental concepts and the underlying principles of delay-Doppler communications. Readers familiar with OFDM will be able to quickly understand the key differences in delay-Doppler domain waveforms that can oversome some of the challenges of high-mobility communications. For the broader readership with a basic knowledge of wireless communications principles, the book provides sufficient background to be self-contained. In each chapter, the book provides a general overview of future search directions and discusses a range of applications of delay-Doppler domain signal processing. With this book the reader will be able to: Recognize the challenges of high mobility channels affected by both multipath and multiple Doppler shifts in physical layer waveform design and performance Understand the limitations of current multicarrier techniques such as OFDM in high mobility channels Recognize the mathematical and physical relations between the different domains for representing channels and waveforms: time-frequency, time-delay, delay-Doppler Understand the operation of the key blocks of a delay-Doppler modulator and demodulator both analytically and by hands-on Matlab exmaples Master the special features and advantages of OTFS with regard to channel estimation, MIMO, multiuser MIMO, and performance Realize the importance of delay-Doppler communications for current and furure applications, e.g., 5G and beyond First book on Delay Doppler CommunicationsWritten by two of the leading authorities in the fieldIncludes a wide range of applications
