Wireless communications are rapidly expanding. Cellular phones, satellite phones, handheld computers and personal navigation systems capable of pinpointing a location within a few feet are becoming connected through new generations of wireless services and the Internet. Anyone can now be reached anywhere and at any time.
The aim of this book is to provide the reader with a comprehensive understanding of mobile technologies and why they are important in every day work. In Chapter 1, the basics of mobile technology and mobile products services and applications to business are explained. Mobile Internet and data services are defined and their applications to business are explored in Chapter 2. Chapter 3, Software and Protocols, discusses the rapidly emerging wireless programs and technical standards that make mobile communications work. Chapter 4, Software-defined Radios, takes a look at a fast emerging technology that may soon change the way mobile phones and other wireless devices are designed, serviced and used. The various types of messaging services available to the business user are described in detail in Chapter 5. Chapter 6 discusses how mobile devices, services and special features fit in the mobile mix. Chapter 7, Cellular Communications and Specialized Mobile Radios, provides a good background in cellular communications. Location-based services are discussed in Chapter 8, covering the technology and services that enable location-specific information to be delivered to mobile devices. Chapter 9, Mobile Commerce Applications, looks at mobile shopping, wireless advertising and methods for applying mobile technologies to business. Security and privacy issues and electronic payments are covered in Chapters 10 and 11. Chapter 12 considers the next generation systems and beyond.
Each chapter consists of several questions and answers. Bullet points that highlight key facts or issues surrounding the questions are included. In addition, the book contains an extensive glossary, which defines and explains many of the terms and acronyms used.

Joint time-frequency analysis has been a topic of much interest in the signal processing community in the past decade. The intent of this book is to provide a summary of the authors' research into applying time-frequency transforms to radar applications. In particular, the focus is on the extraction of target features from the radar-backscattered signal for the purpose of signature diagnostics and automatic target recognition.
In Chapter 1, a brief introduction to radar concepts is provided, including radar-backscattering principles, radar waveforms, noise and clutter, ambiguity functions, matched filter and pulse compression. An overview of joint time-frequency transform is given in Chapter 2. The discussions cover both linear transforms such as the short-time Fourier transform, the continuous wavelet transform and the adaptive spectrogram, and bilinear transforms, including the Wigner-Ville distribution, Cohen's class and the time-frequency distribution series. Chapter 3 discusses the use of time-frequency transforms in the detection and extraction of radar signal in noise. Chapters 4 and 5 offer the main developments of time-frequency transforms for radar-signal analysis and image processing. The use of time-frequency transforms for one-dimensional radar range profiles is described as well as how time-frequency analysis is used for radar imaging of multiple targets. Chapters 6, 7 and 8 describe more specific applications of time-frequency transforms for radar such as the use of joint time-frequency analysis for ISAR motion compensation and the use of time-frequency transforms in SAR imaging of moving targets. In Chapter 8, the use of time-frequency transforms to analyze the micro-Doppler phenomenon on targets is described. Chapter 9 concludes by providing current trends and future outlooks in applying time-frequency transforms for radar applications. This book mainly emphasizes the application perspective, that is how and what type of time-frequency transform can be used to carry out radar signal processing and extract relevant target information effectively.
