Given the rapid software and hardware developments in DSP, it is vital for students to complement their theoretical learning with practical applications. Digital Signal Processing Laboratory is a practical, readily understandable text for those studying DSP for the first time. The author acquaints students with an integrated approach consisting of side-by-side training in theory and hardware/software aspects of DSP, making it ideal for the companion laboratory to a class in DSP theory.

To execute this approach, each chapter consists of a brief section on theory to explain the underlying mathematics and principles, a problem solving section, and a computer laboratory section with programming examples and exercises using MATLAB and Simulink. Applicable chapters include a hardware laboratory section composed of exercises using test and measuring equipment. The author discusses the theory of DSP applications and systems, LTI discrete-time signals and systems, practical time and frequency analysis of discrete-time signals, Analog-to-Digital (A/D) process, design and application of digital filters, and the application of practical DSP processes through the DSP hardware, along with software models of these systems.

This textbook/lab manual offers a concise, easily understood presentation that makes the information accessible to senior undergraduate and graduate students while building their proficiency with the software, the hardware, and the theory of DSP. Students can easily adapt the concepts for different software/hardware conditions than those presented within, making this an extremely versatile and valuable resource.

Roaming in Wireless Networks

http://rapidshare.com/files/91907319/0071455051.rar

McGraw-Hill Professional; 1 edition | ISBN: 0071455051 | 324 pages | September 28, 2005 | PDF | 1 Mb

A cell phone’s roaming feature allows the user to get service when traveling beyond the boundaries of his/her service provider. Wireless service providers make approximately 30% of their operating profit from roaming. But despite being a major source of income, roaming suffers from a number of technological problems in the handoff between networks. Signal strength is wildly variable, calls are frequently dropped, and quality of service is poor. Based upon training courses the author teaches at Agilent and Hewlett-Packard, this is the first book to give communications engineers the know-how to faultlessly design and manage roaming services.

Antenna

Book Description
The Latest Resource for the Study of Antenna Theory! In a discipline that has experienced vast technological changes, this text offers the most recent look at all the necessary topics. Highlights include:
* New coverage of microstrip antennas provides information essential to a wide variety of practical designs of rectangular and circular patches, including computer programs.
* Applications of Fourier transform (spectral) method to antenna radiation.
* Updated material on moment methods, radar cross section, mutual impedances, aperture and horn antennas, compact range designs, and antenna measurements.
A New Emphasis on Design! Balanis features a tremendous increase in design procedures and equations. This presents a solid solution to the challenge of meeting real-life situations faced by engineers. Computer programs contained in the book-and accompanying software-have been developed to help engineers analyze, design, and visualize the radiation characteristics of antennas.

AN INTRODUCTION TO STEPPER MOTORS

Square 1 Electronics' new book, "Easy Step'n", An Introduction to Stepper Motors for the Experimenter," explains to the reader how to determine surplus motor electrical and mechanical specs by using easy-to-build electrical and mechanical test equipment. The experimenter will learn to design and build microcontroller based control systems and to design and build driver circuits to switch power applied to stepper motor windings. The book is hands-on and full of experiments. The format of the books uses flow charts and many code examples in a step-by-step approach.
