This book focuses on the propagation characterization and channel modeling of Unmanned Aerial Vehicle (UAV) communications. Currently, there are no books that cover this specific topic. The authors fill in this void by elaborating accurate yet easy-to-use UAV channel models. The authors also present such topics as propagation characteristics of  UAV communications, a time stationary regular-shaped geometry-based stochastic model (RS-GBSM) for UAV narrowband channels. It also introduces a time non-stationary RS-GBSM for UAV narrowband channels, a time non-stationary RS-GBSM for UAV wideband channels, a time-space non-stationary irregular-shaped geometry-based stochastic model (IS-GBSM) for UAV wideband channels and more. Finally, this book closes up with some promising directions, hoping to promote future research outcomes in the field of  UAV channel modeling.

As the UAV technology matures rapidly, UAV communications are shifting from military development to civilian and commercial sectors. The UAV communication is widely considered as a significant and indispensable component of wireless communications. It is well known that an accurate yet easy-to-use UAV channel model is the foundation of designing a proper UAV communication system and evaluating its performance. This book also provides valuable suggestions for the design of UAV communication systems by adequately presenting the UAV propagation characterization and channel modeling.

This book is mainly written for researchers and professionals working in wireless communications. Advanced-level students majoring in computer science or electrical engineering may also find the content useful as a secondary textbook.

Fractional calculus and its applications are fascinating research areas in many engineering disciplines. This book is a comprehensive collection of research from the author''s group, which is one of the most active in the fractional calculus community worldwide and is the birthplace of one of the four MATLAB toolboxes in fractional calculus, the FOTF Toolbox. The book presents high-precision solution algorithms for a variety of fractional-order differential equations, including nonlinear, delay, and boundary value equations. Currently, there are no other universal solvers available for the latter two types of equations.

Through this book, readers can systematically study the mathematics and solution methods in the field of fractional calculus and apply these concepts to different engineering fields, particularly control systems engineering.

This book is a translation of an original German edition. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation.
