Wireless Technology will play a key role in uplifting the economies of the Emerging countries globally." Ashok Chandra, Wireless Advisor to Govt. of India"

This innovative book provides a stimulating introduction to analog electronics by analyzing the design and construction of a radio transceiver. The author provides essential theoretical background at each step, along with carefully designed laboratory and homework exercises. This structured approach ensures a good grasp of basic electronics as well as an excellent foundation in wireless communications systems. The author begins with a thorough description of basic electronic components and simple circuits. He then describes the key elements of radio electronics, including filters, amplifiers, oscillators, mixers, and antennas. In the laboratory exercises, he leads the reader through the design, construction, and testing of a popular radio transceiver (the NorCal 40A), thereby illustrating and reinforcing the theoretical material. A diskette containing the widely known circuit simulation software, Puff, is included in the book. This book, the first to deal with elementary electronics in the context of radio, can be used as a textbook for introductory analog electronics courses, or for more advanced undergraduate classes on radio-frequency electronics. It will also be of great interest to electronics hobbyists and radio enthusiasts.

In 1873, Scottish physicist James Clerk Maxwell first advanced the idea that there might be electromagnetic waves that were similar to light waves, a startling concept to the scientists of his day. About 13 years later, German physicist Heinrich Hertz demonstrated in his laboratory that electromagnetic radiation did indeed exist. But it was not until after Hertz's death that a young Italian named Guglielmo Marconi got the idea for a practical communications system based on Hertz's work. Marconi was surprised and disappointed that the Italian government was not interested in his newly discovered wireless communications system, and thus he took his equipment to England. From that point on, the wireless became identified with Britain. From these beginnings, wireless radio became the basis of a revolution that has resulted in the satellite communications of today. This history first looks at Marconi's invention and then explores its many applications, including marine radio, cellular telephones, police and military uses, television and radar. Radio collecting is also discussed, and brief biographies are provided for the major figures in the development and use of the wireless.

Full coverage of the techniques needed to implement an autonomous software-defined radio system

This book introduces the reader to the concept of an autonomous software-defined radio (SDR) receiver, which automatically recognizes attributes of an incoming signal and reconfigures itself to receive it. This is in contrast to conventional software-defined radios, which are reconfigurable but not autonomous.

The book explores the challenges of such automatic reconfiguration, and explains the design and development of algorithms that permit its successful operation. Among the topics covered are automatic identification of the carrier frequency, modulation index, data rate, modulation type, and pulse shape, based on observations of the received signal.

Each distinct aspect of the design of the receiver is treated in a separate chapter written by one or more leading innovators in the field. Chapters begin with a problem statement and then offer a full mathematical derivation of an appropriate solution, a decision metric or loop-structure as appropriate, and performance results.

Two of the chapters serve specifically to pull all the individual elements together and help readers see how a successful autonomous SDR receiver works: Chapter 2, The Electra Radio, provides a detailed review of NASA's Electra radio, which was developed for deep space applications Chapter 11, Implementation and Interaction of Estimators and Classifiers, the final chapter, demonstrates the performance of an actual software implementation of the various algorithms working in concert with each other

In summary, all the materials and techniques that an engineer needs to implement an autonomous SDR areincluded. Although the technology is intended for deep space applications, the theoretical development and algorithms presented in this text can be applied to any terrestrial radio with the capability of processing more than one type of signal.

Kick off your shoes, put on your sunglasses, and get ready for a nostalgic trip back to the heyday of portable music. Transistor radios, those quintessential '50s and '60s accompaniments for the beach, backyard, and shirt pocket, have become one of the most popular and colorful collectors' items of recent years. Packed with over 460 full color photographs, this book provides an overview of the endless variety of transistor radio types, sizes, and styles produced during the prolific early years of their development. Over 1,000 radios are featured here, from American manufacturers such as Admiral, Bulova, Emerson, Philco, Regency, and Zenith and from Japanese manufacturers such as Hitachi, Koyo, NEC, Realtone, Sony, and Toshiba. Each radio is identified by manufacturer, model number, number of transistors, special features, country of origin, and date. Wherever possible, the sets are grouped to show radios which share common features, such as manufacturer, marketing organization, type of radio, or style. Shown as well are the color variations and cabinet variations which exist for many of the most popular radios. You'll learn which of the manufacturers marketed their sets under different names or to different organizations and which sets, although bearing different names, are virtually identical. A complete value guide is included to help collectors determine the value of various models with similar styling and features.

The merging of voice and data on a single network opens powerful new possibilities in communications. Only a fundamental understanding of both technologies will ensure you are equipped to maximise their full potential.
