A complete discussion of MIMO communications, from theory to real-world applications

The emerging wireless technology Wideband Multiple-Input, Multiple-Output (MIMO) holds the promise of greater bandwidth efficiency and wireless link reliability. This technology is just now being implemented into hardware and working its way into wireless standards such as the ubiquitous 802.11g, as well as third- and fourth-generation cellular standards.

Multiple-Input Multiple-Output Channel Models uniquely brings together the theoretical and practical aspects of MIMO communications, revealing how these systems use their multipath diversity to increase channel capacity. It gives the reader a clear understanding of the underlying propagation mechanisms in the wideband MIMO channel, which is fundamental to the development of communication algorithms, signaling strategies, and transceiver design for MIMO systems.

MIMO channel models are important tools in understanding the potential gains of a MIMO system. This book discusses two types of wideband MIMO models in detail: correlative channel models—specifically the Kronecker, Weichselberger, and structured models—and cluster models, including Saleh-Valenzuela, European Cooperation in the field of Scientific and Technical Research (COST) 273, and Random Cluster models. From simple to complex, the reader will understand the models'' mechanisms and the reasons behind the parameters. Next, channel sounding is explained in detail, presenting the theory behind a few channel sounding techniques used to sound narrowband and wideband channels. The technique of digital matched filtering is then examined and, using real-life data, is shown to provide very accurate estimates of channel gains. The book concludes with a performance analysis of the structured and Kronecker models.

Multiple-Input Multiple-Output Channel Models is the first book to apply tensor calculus to the problem of wideband MIMO channel modeling. Each chapter features a list of important references, including core literary references, Matlab implementations of key models, and the location of databases that can be used to help in the development of new models or communication algorithms. Engineers who are working in the development of telecommunications systems will find this resource invaluable, as will researchers and students at the graduate or post-graduate level.

Occupational Safety and Hygiene VI collects recent papers of selected authors from 21 countries in the domain of occupational safety and hygiene (OSH). The contributions cover a wide range of topics, including:- Occupational safety- Risk assessment- Safety management- Ergonomics- Management systems- Environmental ergonomics- Physical environment- Construction safety, and- Human factors

Occupational Safety and Hygiene VI represents the state-of-the-art on the above mentioned domains, and is based on research carried out at universities and other research institutions. Some contributions focus more on practical case studies developed by OSH practitioners within their own companies. Hence, the book provides practical tools and approaches currently used by OHS practitioners in a global context.

This book gathers cutting-edge research and best practices relating to occupational risk and safety management, healthcare and ergonomics. It covers strategies for different industries, such as construction, chemical and healthcare. It emphasises challenges posed by automation, discusses solutions offered by technologies, and reports on case studies carried out in different countries. Chapters are based on selected contributions to the 18th International Symposium on Occupational Safety and Hygiene (SHO 2022), held on September 8–9, 2022, in Porto, Portugal. By reporting on different perspectives, such as the ones from managers, workers and OSH professionals, and covering timely issues, such as implications of telework ,issues related to gender inequality and applications of machine learning techniques in occupational health, this book offers extensive information and a source of inspiration to OSH researchers, practitioners and organizations operating in both local and globalcontexts.
