This Springer Brief investigates spectrum sharing with limited channel feedback in various cognitive radio systems, such as point-to-point, broadcast scheduling and ad-hoc networks. The design aim is to optimally allocate the secondary resources to improve the throughput of secondary users while maintaining a certain quality of service for primary users. The analytical results of optimal resource allocation are derived via optimization theory and are verified by the numerical results. The results demonstrate the secondary performance is significantly improved by limited feedback and is further improved by more feedback bits, more secondary receivers and more primary side information.

This SpringerBrief presents interference coordination techniques for future 5G cellular networks. Starting with an overview of existing interference management techniques, it focuses on practical interference coordination schemes based on beamforming and user scheduling. The proposed schemes aim to deal with the inter-cell interference in multi-cell MIMO networks, cross-tier interference in device-to-device communications underlaying cellular network, and inter-network interference in cognitive radio networks. The performances of the proposed schemes are evaluated both analytically and numerically in terms of several performance parameters, including the sum rate, multiplexing gain, and outage probability of the networks. The results show that the proposed schemes can significantly reduce the effect of interference and improve the quality of service of the networks. Interference Coordination for 5G Cellular Networks is suitable for researchers and advanced students interested in interference coordination or 5G cellular networks.

This book is a grand review of the centurial development of rule of law in China. It covers the most important issues in this area and presents “political constitution,” a new interpretative framework that allows the Chinese experience of rule of law to be more fully and correctly expressed. It is especially useful to scholars involved in the study of modern China. The main chapters of this book include: The Constituent Movement in the Late Qing Dynasty; The Xinhai (1911) Revolution; Constitution-making at the Beginning of the Republic of China; The Great Revolution in the 1920s; The Rise of the Party State and its Transition; The Founding of 1949 New China and its Early Constitutional Development; and The Dualist System of Rule of Law in the Reforming Times.

This book comprehensively introduces the drilling theory and practice behind CCSD-1 well drilling, the first stage of a key national scientific engineering project of China. In addition to access to variety of data and information accumulated decade during the project’s decade-long operation, readers also gain insight into state-of-the-art techniques and most recent achievements in China’s scientific drilling industry. Specifically, this work introduces the drilling engineering design, well site construction, and equipment and construction situation. It also provides a minute description on the new techniques that were developed for tackling the technical difficulties, expounds in detail the core drilling techniques for hard rock deep well, and treats diamond core drill bits, reaming drilling techniques in hard crystalline rocks, well-deviation control techniques for strong dipping strata, and much more. In summary, this book offers a valuable resource for engineers and technicians who engage in scientific drilling and a variety of resource drilling engineering; teachers and students who are interested in this field will also gain plentiful information. Prof. Da Wang, the former deputy director of China Geological Survey, was the director of the Engineering Centre, chief engineer and drill-site general director of China Continental Scientific Drilling Project.
