Berg O., Berg T., Haavik S., Hjelmstad J., Skaug R. Spread Spectrum in Mobile Communication

The Institution of Electrical Engineers, 1998. — 478 p.When two of the authors were initially approached by the publishers, they were asked if it would be possible to update the work 'Spread spectrum in communication' published in 1985. As the publishers pointed out, a lot has happened recently in the field of spread-spectrum communications, not the least with respect to the use of mobile radio systems and the introduction of radio networks rather than point-to-point radio connections.
The results presented in this book show that so much has changed that it was not really a question of updating the book from 1985 but rather one of writing a completely new book. Any readers of the previous book will thus only recognise a minor re-use of text and figures. The bare fact that we are no longer two co-authors, but five, points to the great widening of the field of spread-spectrum radiocommunications.
The first book did, to a large degree, focus on technology and the implementational aspects relating to radio design and spread-spectrum modulation. To generate and demodulate the spreading codes was a major issue, as was the necessity for methods to synchronise the transmitter and receiver. Today, embedded digital signal-processing power, and the general technology available, has enabled a large variety of possibilities for practical spread-spectrum implementations. At the same time, the integration and use of data-network protocols in radios enables the development of radio systems with the kind of functionality and menu of services previously only possible for wired systems.Designing systems to meet user requirements
