出版日期: 2013年12月5日 This book is an in-depth, systematic and structured technical reference on 3GPP's LTE-Advanced (Releases 10 and 11), covering theory, technology and implementation, written by an author who has been involved in the inception and development of these technologies for over 20 years. The book not only describes the operation of individual components, but also shows how they fit into the overall system and operate from a systems perspective. Uniquely, this book gives in-depth information on upper protocol layers, implementation and deployment issues, and services, making it suitable for engineers who are implementing the technology into future products and services. Reflecting the author's 25 plus years of experience in signal processing and communication system design, this book is ideal for professional engineers, researchers, and graduate students working in cellular communication systems, radio air-interface technologies, cellular communications protocols, advanced radio access technologies for beyond 4G systems, and broadband cellular standards. Features: an end-to-end description of LTE/LTE-Advanced technologies using a top-down systems approach, providing an in-depth understanding of how the overall system works; detailed algorithmic descriptions of the individual components' operation and inter-connection; strong emphasis on implementation and deployment scenarios, making this a very practical book; an in-depth coverage of theoretical and practical aspects of LTE Releases 10 and 11; and clear and concise descriptions of the underlying principles and theoretical concepts to provide a better understanding of the operation of the system's components. It covers all essential system functionalities, features, and their inter-connections based on a clear protocol structure, including detailed signal flow graphs and block diagrams. It includes methodologies and results related to link-level and system-level evaluations of LTE-Advanced. It provides understanding and insight into the advanced underlying technologies in LTE-Advanced up to and including Release 11: multi-antenna signal processing, OFDM, carrier aggregation, coordinated multi-point transmission and reception, eICIC, multi-radio coexistence, E-MBMS, positioning methods, real-time and non-real-time wireless multimedia applications.

understanding digital signal processing 这是一本广受好评的数字信号处理图书,作者R. Lyons同时还是IEEE信号处理杂志的副主编,负责信号处理技巧专栏。这本书不仅写得通俗易懂,而且与通用的教材结合非常紧密,堪称是学院派与实用性完美结合的典范。实际上,这本书也重新定义了教材著作的范式,成为优秀教科书的代表。与上面那本smith的书相比,数学公式稍多一些,但不难理解。例子也非常丰富,还提供了很多的信号处理技巧。这本书的英文版在2010年已经出了第三版。中文版好像只有第二版,译者是朱光明。不过中文版现在好像到处无货,估计第三版的中文版也会很快上市。从淘宝网购得,保证不后悔!

Navigation is defined as the science of getting a craft or person from one place to another. Each of us conducts some form of navigation in our daily lives. Driving to work or walking to a store requires that we employ fundamental navigation skills. For most of us, these skills require utilizing our eyes, common sense, and landmarks. However, in some cases where a more accurate knowledge of our position, intended course, or transit time to a desired destination is required, navigation aids other than landmarks are used. These may be in the form of a simple clock to determine the velocity over a known distance or the odometer in our car to keep track of the distance traveled. Some other navigation aids transmit electronic signals and therefore are more complex. These are referred to as radionavigation aids.

Maple is a computer program capable of performing a wide variety of mathematical operations. It originated in the early 1980s as a computer algebra system, but today this description doesn’t really do it justice. Maple has facilities for algebra, calculus, linear algebra, graphics (twoand three-dimensional plots, and animations), numerical calculations to arbitrary precision, and many other things besides. It is widely used in universities across the world, and is particularly useful for tasks that are tedious and error-prone when performed by humans, such as manipulating complicated series expansions and solving large sets of simultaneous equations. Used correctly, Maple can save time and quickly solve problems that would otherwise be intractable. Used incorrectly, it can lead to frustration, and the destruction of expensive IT equipment. At the time of writing, the current version is Maple 2016. Versions before Maple 2015 were numbered starting from 1; the last of these was Maple 18. New features introduced in each version from Maple 4.0 onwards can be viewed using the help system (see Section 2.2). For the most part, recent changes have been relatively minor, at least as far as the material in this book is concerned. Consequently, all of the examples work with both Maple 2015 and Maple 2016. In fact, most will work in older versions as well, though naturally the number of exceptions increases the further back one goes. Two substantial new features are the dataplot command, discussed in Section 6.6, and the new rules concerning terminating characters, described in Appendix B (see also Section 2.3). Both of these were introduced in Maple 2015.
