Wideband TDD WCDMA for the Unpaired Spectrum
This book is an outgrowth of the pioneering development work done by Inter Digital Communication Corporation in 3rd Generation TDD WCDMA Technology. Many engineers and managers were involved in this development, which spanned a wide range of technology areas, including system architecture, radio interface, radio modem design, radio resource management and hardware/software implementation. In addition, TDD WCDMA technology had many direct and...

Smart antennas involve processing of signals induced on an array of sensors such as antennas, microphones, and hydrophones. They have applications in the areas of radar, sonar, medical imaging, and communications. Smart antennas have the property of spatial filtering, which makes it possible to receive energy from a particular direction while simultaneously blocking it from another direction. This property makes smart antennas a very effective...

Propagation Handbook for Wireless Communication System Design
Wireless means different things to different people. For this book, it refers to the radio systems that provide point-to-point, point-to-multipoint, and Earth-space communications over transmission links that propagate outside buildings through the lower atmosphere. Wireless systems are being built that provide data transmission between computers and other devices on one’s own desk. These are part of the wireless world but not the part...

Principles of spread-spectrum commnication systems
The goal of this book is to provide a concise but lucid explanation and derivation of the fundamentals of spread -spectrum communication systems. Although spread-spectrum communication is a staple topic in textbooks on digital communication, its treatment is usually cursory, and the subject warrants a more intensive exposition. Originally adopted in military networks as a means of ensuring secure communication when confronted with the threats...

The performance of digital signal processing and communication systems is generally limited by the precision of the digital input signal which is achieved at the interface between analog and digital information. Sigma-Delta (S-D) modulation based analog-todigital(A/D) conversion technology is a cost effective alternative for high resolution (greater than 12 bits) converters which can be ultimately integrated on digital signal processor ICs.

Optical switching and networking handbook
Before you begin to read this book, please take a moment to read these introductory comments. The title of the book may be misleading for many people: For the engineering person, this may sound like the bible of optical networks and switching systems. Not so! This is not an engineering book and will not dig into the gory details of bits and bytes, ohms and lamdas, and so on. It will help an engineering person to understand the marketplace for...
