  • Near-Capacity+Multi-Functional+MIMO+Systems

    The family of recent wireless stAndards included the optional employment of MIMO tyechniques. This was motivated by the observation according to the classic Shannon-Hartley law the achiev- able channel capacity increases logarithmically with the transmit power. By contrast, the MIMO capacity increases linearly with the number of transmit antennas, provided that the number of receive antennas is equal to the number of transmit antennas.

  • OFDM+Baseband+Receiver+Design

    All wireless communication stAndards, existing and under development, adopt or consider adopting orthogonal frequency-division multiplexing (OFDM) as the modulation technique. It is clear that OFDM has become the definitive modulation scheme in current and future wireless communication systems.

  • OFDM+Wireless+LANS

    Before delving into the details of orthogonal frequency division multiplexing (OFDM), relevant background material must be presented first. The purpose of this chapter is to provide the necessary building blocks for the development of OFDM principles. Included in this chapter are reviews of stochastic and random process, discrete-time signals and systems, and the Discrete Fourier Transform (DFT). Tooled with the necessary mathematical foundation, we proceed with an overview of digital communication systems and OFDM communication systems. We conclude the chapter with summaries of the OFDM wireless LAN stAndards currently in existence and a high-level comparison of single carrier systems versus OFDM.

  • Radio+Resource+Allocation

    We are currently witnessing an increase in telecommunications norms and stAndards given the recent advances in this domain. The increasing number of normalized stAndards paves the way for an increase in the range of offers and services available for each consumer. Moreover, the majority of available radio frequencies have already been allocated.

  • Radio+Resource+Management

    Wireless communications and networking technology are advancing at a very rapid pace. Newer technologies and stAndards are evolving to serve the ever-increasing num- ber of users demanding different types of mobile applications and services. Research and development activities on wireless technology constitute one of the most impor- tant segments of research and development in the telecommunications area today.

  • Radio+Spectrum+Management

    An understanding of the policies, regulations, stAndards and techniques of radio spectrum management is useful to those who manage and administrate it, to operators, to equipment providers and to the users of wireless communication (i.e., all of us). For many years the author has been deeply involved in ruling the RF spectrum at the national, regional and global levels. The book is based on the professional experience of the author, his academic courses, presenta- tions and tutorials in five continents. The book reflects this legacy and will be of use to engineers, lawyers and economists, who serve the global industry of the wireless world; in it they may find solutions to the problems they frequently encounter.

  • SAE and the Evolved Packet Core

    The outcome of the 3GPP SAE (system architecture evolution) technical study and specification work is a set of stAndards that specifies the evolution of the packet core network for GSM/GPRS and WCDMA/HSPA to an all-IP architec- ture and enables a feature-rich ‘common packet core’ for radio accesses devel- oped within 3GPP and also by other standardization fora.

  • Service Delivery Platforms

    Convergence between the two largest networks (Telecom and IP) is taking place very rapidly and at diff erent levels: (1) network level: unifi cation of IP networks with traditional Telecom networks through evolving stAndards (Session Initiation Protocol (SIP), Realtime Transfer Protocol (RTP), SS7, 3G) to support interopera- bility; (2) service level: traditional Telecom services like voice calls are being provi- sioned on the IP backbone (VoIP), while traditional IP services (most data-driven services such as multimedia, browsing, chatting, gaming, etc.) are accessible over the Telecom network.
