Propagation Channel Characterization, Parameter Estimation, and Modeling for Wireless Communications

By: Xuefeng Yin,Xiang Cheng

A comprehensive reference giving a thorough explanation of propagation mechanisms, channel characteristics results, measurement approaches and the modelling of channels Thoroughly covering channel characteristics and parameters, this book provides the knowledge needed to design various wireless systems, such as cellular communication systems, RFID and ad hoc wireless communication systems. It gives a detailed introduction to aspects of channels before presenting the novel estimation and modelling techniques which can be used to achieve accurate models. To systematically guide readers through the topic, the book is organised in three distinct parts. The first part covers the fundamentals of the characterization of propagation channels, including the conventional single-input single-output (SISO) propagation channel characterization as well as its extension to multiple-input multiple-output (MIMO) cases. Part two focuses on channel measurements and channel data post-processing. Wideband channel measurements are introduced, including the equipment, technology and advantages and disadvantages of different data acquisition schemes. The channel parameter estimation methods are then presented, which include conventional spectral-based estimation, the specular-path-model based high-resolution method, and the newly derived power spectrum estimation methods. Measurement results are used to compare the performance of the different estimation methods. The third part gives a complete introduction to different modelling approaches. Among them, both scattering theoretical channel modelling and measurement-based channel modelling approaches are detailed. This part also approaches how to utilize these two modelling approaches to investigate wireless channels for conventional cellular systems and some new emerging communication systems. This three-part approach means the book caters for the requirements of the audiences at different levels, including readers needing introductory knowledge, engineers who are looking for more advanced understanding, and expert researchers in wireless system design as a reference. Presents technical explanations, illustrated with examples of the theory in practice Discusses results applied to 4G communication systems and other emerging communication systems, such as relay, CoMP, and vehicle-to-vehicle rapid time-variant channels Can be used as comprehensive tutorial for students or a complete reference for engineers in industry Includes selected illustrations in color Program downloads available for readers Companion website with program downloads for readers and presentation slides and solution manual for instructors Essential reading for Graduate students and researchers interested in the characteristics of propagation channel, or who work in areas related to physical layer architectures, air interfaces, navigation, and wireless sensing

Geomechanical Behaviors of Deeply Buried Rock under Triaxial Disturbed Stress Conditions

By: Yu Wang,Xuefeng Yi,Lei Yin

This book is intended as a reference book for advanced graduate students and research engineers in rock mechanics related to civil, mining, hydropower, and traffic engineering, etc. For rock mass during construction, they are often subjected to complicated stress disturbance conditions, such as human-induced and environmental loading acting on rock that is cyclic or fatigue in nature. Typical forms of stress disturbance include excavation unloading, blasting vibration, earthquake, drilling and vehicle loading, etc. Usually, the stress disturbance condition is inferred as a kind of dynamic loading and differs dramatically from those under static loads. Along with the constructions on rock mass, a lot of disasters, e.g., tunnel rockburst, induced seismicity and sand liquefaction, are cyclic and dynamic processes. Nevertheless, insufficient attentions have been paid to the influences of disturbed stress on the long-term stability of rock mass construction so far. The discrepancy between theoretical prediction (by approximating the dynamic problems as static ones) and actual performance of constructed engineering structures is usually tolerated. As a result, investigation of the disturbed stress on rock is always vital to the rational design and the long-term stability prediction of rock constructions.

Nonparametric Bayesian Learning for Collaborative Robot Multimodal Introspection

By: Xuefeng Zhou

This open access book focuses on robot introspection, which has a direct impact on physical human-robot interaction and long-term autonomy, and which can benefit from autonomous anomaly monitoring and diagnosis, as well as anomaly recovery strategies. In robotics, the ability to reason, solve their own anomalies and proactively enrich owned knowledge is a direct way to improve autonomous behaviors. To this end, the authors start by considering the underlying pattern of multimodal observation during robot manipulation, which can effectively be modeled as a parametric hidden Markov model (HMM). They then adopt a nonparametric Bayesian approach in defining a prior using the hierarchical Dirichlet process (HDP) on the standard HMM parameters, known as the Hierarchical Dirichlet Process Hidden Markov Model (HDP-HMM). The HDP-HMM can examine an HMM with an unbounded number of possible states and allows flexibility in the complexity of the learned model and the development of reliable and scalable variational inference methods. This book is a valuable reference resource for researchers and designers in the field of robot learning and multimodal perception, as well as for senior undergraduate and graduate university students.

Teacher Education in Professional Learning Communities

Lessons from the Reciprocal Learning Project

By: Xuefeng Huang

This book explores the unique experiences of a sister school network in Canada and China contextualized through the lens of the Reciprocal Learning Project, which supports the relationship between a school network and teacher education exchange program of two countries. Huang uses theoretical viewpoints from teacher learning and comparative education research to analyse and interpret what has happened in the emerging cross-cultural school network. The book juxtaposes teacher learning and comparative education research from Shanghai and Ontario as teachers in the two places interact and provides detailed descriptions of teacher collaboration to show how these collaborations were initiated, developed, and sustained, as well as the impact brought about from these collaborations. The book offers a unique opportunity to examine how Canadian and Chinese teachers receive and react to opportunities of cross-cultural collaboration and learning.

Improving Village Governance in Contemporary China

By: Xuefeng He

Based on an in-depth investigation of different regions of China's vast countryside, Improving Village Governance in Contemporary China vividly describes rural governance mechanisms against the background of China's rapid urbanization. China’s rural areas vary greatly from region to region with respect to the pace and mode of change. Rural governance in China is decided by how the state transfers resources to villages, and by the linkage between the transfer style and the specific situation of each village. Only when grassroots governance is based on rural democracy (with peasants as the core) can villages become more harmonious.

Deep Reinforcement Learning with Guaranteed Performance

A Lyapunov-Based Approach

By: Yinyan Zhang,Shuai Li,Xuefeng Zhou

This book discusses methods and algorithms for the near-optimal adaptive control of nonlinear systems, including the corresponding theoretical analysis and simulative examples, and presents two innovative methods for the redundancy resolution of redundant manipulators with consideration of parameter uncertainty and periodic disturbances. It also reports on a series of systematic investigations on a near-optimal adaptive control method based on the Taylor expansion, neural networks, estimator design approaches, and the idea of sliding mode control, focusing on the tracking control problem of nonlinear systems under different scenarios. The book culminates with a presentation of two new redundancy resolution methods; one addresses adaptive kinematic control of redundant manipulators, and the other centers on the effect of periodic input disturbance on redundancy resolution. Each self-contained chapter is clearly written, making the book accessible to graduate students as well as academic and industrial researchers in the fields of adaptive and optimal control, robotics, and dynamic neural networks.
