Data Communications In Europe 1983 1991

Provides up-to-date information on analyzing practical international telecommunications problems and how to choose from the alternatives available to solve them. Written in non-technical terms, this volume brings information that until now was widely scattered throughout the literature. Chapters cover the information center, the worldwide environment, the flow of international information, network attachment products, office systems, digital voice and data networks, U.S. network services and alternatives, international traffic, value-added networks, telematics, satellite communications, and future trends. Features a directory of U.S. common carriers, domestic and international, and a directory of international PTT's for 160 countries.

This volume contains the proceedings of the Tenth International Congress on Medical Informatics, MIE 91, that will be held in Vienna, Austria, August 19-22, 1991. The MIE 91 Congress was organized by the European Federation for Medical Informatics (EFMI) in cooperation with the Austrian Computer Society (OCG) and the Austrian Society for Biomedi cal Engineering (OGBMT). It follows the previous congresses in Cambridge (1978), Berlin (1979), Toulouse (1981), Dublin (1982), Brussels (1984), Helsinki (1985), Rome (1987), Oslo (1988), and the Congress 1990 in Glasgow. The proceedings contain 199 contributions to the MIE 91 Congress. They cover all presentations which are part of the scientific programme of MIE 91, among them 157 paper presentations with an average of five pages, 28 poster presentations again with an average of five pages, and 14 abstracts of demonstrations with an average of one page. The papers included were selected by an International Programme Committee out of over 300 submissions after careful review by at least two international reviewers (for whose estimable efforts we are especially thankful). The recommendations of the re viewers were incorporated in the final texts. Some papers were reworked by a professional translator to obtain a high quality of presentation. Several submissions could not be considered for presenta tion at MIE 91 because of shortage of congress time and limitations in the number of pages of the proceedings.

This work provides a detailed introduction to: the current state of mobile data communications systems; the future wireless network; the radio propagation environment; error-control techniques; protocols; architectures; applications; and systems standards that support data communications.

Multi-Carrier Techniques for Broadband Wireless Communications provides an accessible introduction to OFDM-based systems from a signal processing perspective. The first part presents a concise treatment of some fundamental concepts related to wireless communications and multicarrier systems, while the second offers a comprehensive survey of recent developments on a variety of critical design issues. These include synchronization techniques, channel estimation methods, adaptive resource allocation and practical schemes for reducing the peak-to-average power ratio of the transmitted waveform.
