    The synergy between digital radio communications and VLSI signal processing is revolutionizing the design of wireless terminals. Driving this synergy are certain fundamental paradigms in modern communication theory, digital signal processing, and VLSI design. The authors discuss the modern centers-of-gravity model, which they believe is emerging as the basis for the successful design and implement... View full abstract»

    The authors present an overview of the characteristics of code division multiple access (CDMA) as it is currently being envisioned for use in wireless communications. There are many considerations in the design of such systems, and there are multiple designs being discussed. CDMA has been proposed for both terrestrial links and satellite links. However, there are key differences in the characteris... View full abstract»

    This article specifically focuses on wireless personal communications, i.e., wireless access, that provides either terminal or personal mobility. In particular, we discuss some important issues in networking, traffic, and performance. Although within radio and networking aspects there are significant commonalities between traditional cellular mobile communications and wireless personal communicati... View full abstract»

    The authors describe the type of signals that occur in various environments and the modeling of the propagation parameters. Models are essentially of two classes. The first class consists of parametric statistical models that on average describe the phenomenon within a given error. They are simple to use, but relatively coarse. In the last few years a second class of environment-specific models ha... View full abstract»

    Although the telcos have introduced a host of new services, more service offerings are needed, some of which may require additional functionality with the same signals. The author discusses potential problems associated with the implementation of five new services: universal number; call forwarding ID; remote control of call waiting; smart card; and voice mail View full abstract»

    Many sessions at the International Telecommunications Symposium (ITS) in Rio de Janeiro, Brazil, in August 1994, were multicast through the Internet as live audio and pictures to viewers in the US and elsewhere. The Multicast Backbone (MBONE) frequently carries meetings of the Internet community and special events such as Space Shuttle launchings. It is beginning to be used for workshops and other...

    Time division multiple access (TDMA) is a classic approach to multiple access in digital cellular wireless communications systems. The authors summarize a number of frequency and time slot allocation techniques for enhancing the capacity and flexibility of TDMA-based systems. They also describe how the problems of fading, delay spread, time variability and interference affect TDMA systems, and how... View full abstract»

    The United States Government advanced several initiatives to stimulate the commercialization of technologies. The Federal Technology Transfer Act of 1986 provided the legal basis for the private sector's access to government facilities and technical resources. In 1987, the Malcom Baldridge National Quality Award was established to "stimulate American companies to improve quality and productivity f... View full abstract»

    The greatest single factor in enhancing spectral efficiency of a network is the mass deployment of microcells. By this simple technique we can repeatedly and efficiently reuse the precious spectrum. The number of users a network can support is fundamentally dependent on the common air interface (CAI) over which users communicate. User capacity is dependent on many factors, but the cardinal ones ar... View full abstract»
