This book presents some of the recent developments in the field of optical-wireless coherence communication. The factors affecting the coherence detection sensitivity are analyzed and the approach to approximate the coherence detection limit is discussed. The wavefront distortion caused by atmospheric turbulence is analyzed, and the influence of the wavefront distortion on the coherence detection performance is examined. A new concept of vortex-beam coherence-detection is proposed, and the problem of signal light decomposition into partially coherent light detection is analyzed. This book can benefit researchers, engineers, and graduate students in the field of telecommunications. It is suitable for engineering and technical personnel engaged in applied optics and communications engineering, university teachers, graduate students, and senior undergraduates.

The book focuses on noise models in optical-wireless communication systems. The main contents include noise classification in optical-wireless communication systems, as well as the current research progress at home and abroad, explores the noise mechanism in optical-wireless communication systems, as well as the establishment of a noise model and analysis methods to suppress the noise of optical-wireless communication systems. Combining theory with practice, systematic analysis of all kinds of noise in optical-wireless communication system, so that readers have a comprehensive understanding of the noise in optical-wireless communication system, which is an important feature of this book. The book can benefit senior college students in electronic information, communication engineering, and applied optical majors, as well as graduates, engineers, and technical personnel, etc.
