Wireless technology is a truly revolutionary paradigm shift, enabling multimedia communications between people and devices from any location. It also underpins exciting applications such as sensor networks, smart homes, telemedicine, and automated highways. This book provides a comprehensive introduction to the underlying theory, design techniques and analytical tools of wireless communications, focusing primarily on the core principles of wireless system design. The book begins with an overview of wireless systems and standards. The characteristics of the wireless channel are then described, including their fundamental capacity limits. Various modulation, coding, and signal processing schemes are then discussed in detail, including state-of-the-art adaptive modulation, multicarrier, spread spectrum, and multiple antenna techniques. The concluding chapters deal with multiuser communications, cellular system design, and ad-hoc network design. Design insights and tradeoffs are emphasized throughout the book. It contains many worked examples, over 200 figures, almost 300 homework exercises, over 700 references, and is an ideal textbook for students. The book is also a valuable reference for engineers in the wireless industry. Andrea Goldsmith received her Ph.D. from the University of California, Berkeley, and is an Associate Professor of Electrical Engineering at Stanford University. Prior to this she was an Assistant Professor at the California Institute of Technology. She has Read more...

The market is flooded with numbers of good books on Embedded Systems designed especially with the most popular MCS51 family. These books are traditional in nature i.e. they start with the routine architectural features of 8051, description of registers, ports, interrupts etc. Most of these things are already covered in the device data sheet and application notes. In this book all such routine things are skipped. The focus is on programming microcontrollers, to be specific MCS-51 family in 'C' using Keil IDE. The book presents seventeen live case studies apart from the many basic programs organized around every on-chip resource like port, time/counter, interrupt , serial I/O etc. Rather than introducing the underpinning theory or reproducing lengthy data sheets, our approach is "learning-through-doing" and one that appeals to busy electronics designers. The 'C' codes given are well supported by easy to understand comments wherever required. Mastering the basic modules and hands on working with the projects will enable to grasp the basic building blocks for most 8051 programs. Whether you are a student using the MCS-51 family of microcontrollers for your project work or an embedded systems programmer, this is a book that will give you a kick-start in using and understanding the most popular microcontroller. Authors through their interaction with the undergraduate, postgraduate students as well as industry professionals have found that such a book is a need of the microcontr Read more...

Recognising the benefits of improved control, the second edition of Autotuning of PID Controllers provides simple yet effective methods for improving PID controller performance. The practical issues of controller tuning are examined using numerous worked examples and case studies in association with specially written autotuning MATLABR programs to bridge the gap between conventional tuning practice and novel autotuning methods. The extensively revised second edition expands and refines on important work in the ubiquitous PID form of control with material covering: * Derivation of analytical expressions for relay feedback responses with tabulated results for easy reference. * The use of shapes of relay responses to generate information for improved closed-loop control and performance assessment. * The applications of autotuning to multiple-model-based cases for handling process nonlinearity. * The use of feedback shapes to generate information for performance assessment. * The impact of imperfect actuators on controller performance. Autotuning of PID Controllers is more than just a monograph, it is an independent learning tool applicable to the work of academic control engineers and of their counterparts in industry looking for more effective process control and automation. Comments on the first edition: This book is written in a way which not only makes it easy to understand but is also useful to those interested in or working with PID controllers. Assemb Read more...

More than ever before, complicated mathematical procedures are integral to the success and advancement of technology, engineering, and even industrial production. Knowledge of and experience with these procedures is therefore vital to present and future scientists, engineers and technologists. Mathematical Methods in Physics and Engineering with Mathematica clearly demonstrates how to solve difficult practical problems involving ordinary and partial differential equations and boundary value problems using the software package Mathematica (4.x). Avoiding mathematical theorems and numerical methods-and requiring no prior experience with the software-the author helps readers learn by doing with step-by-step recipes useful in both new and classical applications. Mathematica and FORTRAN codes used in the book's examples and exercises are available for download from the Internet. The author's clear explanation of each Mathematica command along with a wealth of examples and exercises make Mathematical Methods in Physics and Engineering with Mathematica an outstanding choice both as a reference for practical problem solving and as a quick-start guide to using a leading mathematics software package. Review It is a whirlwind review of mathematical methods used to solve linear and nonlinear boundary-value problems. The best aspect of this book is its immersion in Mathematica, which is treated as a full partner in presenting the material. A list of codesand an appendix that lists all Read more...

Mathematical Analysis (often called Advanced Calculus) is generally found by students to be one of their hardest courses in Mathematics. This text uses the so-called sequential approach to continuity, differentiability and integration to make it easier to understand the subject.Topics that are generally glossed over in the standard Calculus courses are given careful study here. For example, what exactly is a 'continuous' function? And how exactly can one give a careful definition of 'integral'? The latter question is often one of the mysterious points in a Calculus course - and it is quite difficult to give a rigorous treatment of integration! The text has a large number of diagrams and helpful margin notes; and uses many graded examples and exercises, often with complete solutions, to guide students through the tricky points. It is suitable for self-study or use in parallel with a standard University course on the subject.
