Aggiungi al carrelloCondizione: Gut. Zustand: Gut | Sprache: Englisch | Produktart: Bücher | The wireless industry is growing at a phenomenal rate. Cellular subscribers are increasing at a rate of 45% per year, the market for wireless local loop service is growing at a rate of 42%, and the wireless local area network market is growing at a rate of 61 %. This growth and potential for future growth has motivated companies to commit $20 billion in obtaining 90 MHz of PCS spectrum during the recent FCC auctions in the United States. Obviously spectrum is a costly, but critical, resource. Efficient utilization of this resource is essential for profitable wireless service. To meet this challenge, researchers in wireless communications are tenaciously developing more spectrally efficient modulation techniques, planning tools for efficient communication system layout, and digital signal processing techniques for more robust communications. The papers and lectures presented in this book were originally given at the Sixth Annual Virginia Tech Symposium on Wireless Personal Communications and cover a broad range of topics in wireless communications. The majority of the papers are relevant to creating higher capacity (spectrally efficient) systems with greater coverage. Topics include adaptive antenna array measurements and algorithm comparisons, Cellular Digital Packet Data deployment guidelines, speech coding techniques, wireless system design methodology, and propagation measurements in hostile or previously unexplored channels.

Aggiungi al carrelloCondizione: Gut. Zustand: Gut | Sprache: Englisch | Produktart: Bücher | Wireless personal communications, or wireless as it is now being called, has arrived. The hype is starting to fade, and the hard work of deploying new systems and services for personal communications is underway. In the United States, the FCC propelled the wireless era from infancy to mainstream with a $7.7 billion auction of 60 MHz of radio spectrum in the 180011900 MHz band. With the largest single sale of public property in the history of mankind mostly complete, the resources of the entire world are being called upon to develop inexpensive, rapidly deployable wireless systems and sub scriber units for an industry that is adding subscribers at greater than 50% annual rate. This growth is commonplace for wireless service companies throughout the world, and in the U.S., where as many as 7 licensed wireless service providers may be competing for cellularfPCS customers within the next couple of years, differentiators in cost, qual ity, service, and coverage will become critical to customer acceptance and use. Many of these issues are discussed in the papers included in this book.

Technology advances and new frequency allocations for personal communication services (PCS) are creating numerous business and technical opportunities. It is becoming clear that an essential requirement for exploiting opportunities is the ability to track the dramatic changes in wireless technology, which is a principal aim of this book. Wireless Personal Communications: Research Developments places particular emphasis on the areas of signal processing, propagation and spread-spectrum, and emerging communication systems. This book contains new results on adaptive antennas for capacity improvements in wireless communication systems, as well as state-of-the-art information on the latest technical developments. Also included are several chapters which discuss the impact of defense conversion on the wireless industry, and related competitive issues. The six parts of the book each focus on a distinct issue in wireless communications. Part I contains several tutorial chapters on key areas in wireless communications. The first chapter is on radio wave propagation for emerging wireless personal communication systems. Chapter two contains a comprehensive study of emerging DSP-based interference rejection techniques for single channel (antenna) systems. Chapter three deals with spread spectrum wireless communications, explaining the concept of spread spectrum, modeling techniques for spread spectrum, and current applications and research issues for spread spectrum systems. Part II focuses on digital signal processing and spread spectrum, two means of creating interference and multipath robust communications. Part III concerns propagation aspects of wireless communications. Part IV discusses the performance of emerging wireless systems. Part V describes the opportunities and pitfalls of defense conversion from the perspective of several U.S. defense firmsthat have successfully made the transition to commercial wireless. The final section discusses a number of competitive issues regarding personal communication services.
