In this paper, we address antenna selection (AS)-aided massive multi-user multiple-input-multiple-output (MU-MIMO).system based on maximum signal-to-noise ratio, where imperfect channel state information (CSI), time-varying channel and.antenna spatial correlation are considered. More explicitly, a computationally simple training-based channel estimator (CE) is.firstly employed for obtaining the imperfect down-link CSI. Channel quantization (CQ) is subsequently introduced by the feedback.link whi

An important working resource for engineers and researchers involved in the design, development, and implementation of signal processing systemsThe last decade has seen a rapid expansion of the use of field programmable gate arrays (FPGAs) for a wide range of applications beyond traditional digital signal processing (DSP) systems. Written by a team of experts working at the leading edge of FPGA research and development, this second edition of FPGA-based Implementation of Signal Processing Systems has been extensively updated and revised to reflect the latest iterations of FPGA theory, applications, and technology. Written from a system-level perspective, it features expert discussions of contemporary methods and tools used in the design, optimization and implementation of DSP systems using programmable FPGA hardware. And it provides a wealth of practical insights—along with illustrative case studies and timely real-world examples—of critical concern to engineers working in the design and development of DSP systems for radio, telecommunications, audio-visual, and security applications, as well as bioinformatics, Big Data applications, and more.

Operating Systems-Three Easy Pieces V1.0, 带书签。 To Everyone Welcome to this book! We hope you’ll enjoy reading it as much as we enjoyed writing it. The book is called Operating Systems: Three Easy Pieces (available at http://www.ostep.org), and the title is obviously an homage to one of the greatest sets of lecture notes ever created, by one Richard Feynman on the topic of Physics [F96]. While this book will undoubtedly fall short of the high standard set by that famous physicist, perhaps it will be good enough for you in your quest to understand what operating systems (and more generally, systems) are all about.

2007年五星书 英文版 Digital Design (Verilog): An Embedded Systems Approach Using Verilog Product Description Digital Design: An Embedded Systems Approach Using Verilog provides a foundation in digital design for students in computer engineering, electrical engineering and computer science courses. It takes an up-to-date and modern approach of presenting digital logic design as an activity in a larger systems design context. Rather than focus on aspects of digital design that have little relevance in a realistic design context, this book concentrates on modern and evolving knowledge and design skills. Hardware description language (HDL)-based design and verification is emphasized--Verilog examples are used extensively throughout. By treating digital logic as part of embedded systems design, this book provides an understanding of the hardware needed in the analysis and design of systems comprising both hardware and software components. Includes a Web site with links to vendor tools, labs and tutorials. Presents digital logic design as an activity in a larger systems design context. Features extensive use of Verilog examples to demonstrate HDL usage at the abstract behavioural level and register transfer level, as well as for low-level verification and verification environments. Includes worked examples throughout to enhance the reader's understanding and retention of the material. Companion Web site includes links to CAD tools for FPGA design from Synplicity, Mentor Graphics, and Xilinx, Verilog source code for all the examples in the book, lecture slides, laboratory projects, and solutions to exercises.

People increasingly use social networks to manage various aspects of their lives such as communication, collaboration, and information sharing. A user’s network of friends may offer a wide range of important benefits such as receiving online help and support and the ability to exploit professional opportunities. One of the most profound properties of social networks is their dynamic nature governed by people constantly joining and leaving the social networks. The circle of friends may frequently change when people establish friendship through social links or when their interest in a social relationship ends and the link is removed. This book introduces novel techniques and algorithms for social network-based recommender systems. Here, concepts such as link prediction using graph patterns, following recommendation based on user authority, strategic partner selection in collaborative systems, and network formation based on “social brokers” are presented. In this book, well-established graph models such as the notion of hubs and authorities provide the basis for authority-based recommendation and are systematically extended towards a unified Hyperlink Induced Topic Search (HITS) and personalized PageRank model. Detailed experiments using various real-world datasets and systematic evaluation of recommendation results proof the applicability of the presented concepts.
