Preface

We are pleased to present this edited volume, *MIMO Communications – Fundamental Theory, Propagation Channels, and Antenna Systems*. This book introduces and discusses the latest research and developments in MIMO communications, serving as a comprehensive resource for scholars, researchers, industry professionals, and engineers.

The volume is divided into four parts: "Wireless Communications", "Antenna Techniques", "Channel Modeling", and "Autonomous Driving and Radars". Each part features contributions from esteemed experts in the field, covering a wide range of topics, including capacity analysis of MIMO channels, beamforming and antenna array design, channel modeling and estimation, and the applications of autonomous driving and radars.

Section 1, "Wireless Communications", lays out the fundamental theory of MIMO communications, providing a detailed introduction to the key concepts and techniques involved in designing and analyzing MIMO systems.

Section 2, "Antenna Techniques", discusses various types of antenna arrays, radiation patterns, and design techniques, and covers critical aspects of MIMO communication systems such as antenna selection and beamforming.

Section 3, "Channel Modeling", examines the various aspects of MIMO channels, including channel models, multipath fading, spatial correlation, and more advanced topics such as channel estimation and feedback.

Section 4, "Autonomous Driving and Radars", provides a comprehensive overview of the field of autonomous driving, including the history, challenges, and applications of this technology, and covers the basics of radar, including its principle, design, and implementation.

We want to take this opportunity to acknowledge the authors' hard work and contributions and the support of the editorial team. We hope this volume will serve as a valuable resource for scholars, researchers, and industry professionals and that the insights and perspectives presented in this volume will help advance the MIMO communication fields.
