Описание: Principles of Mobile Communication, Third Edition, is an authoritative treatment of the fundamentals of mobile communications. This book stresses the fundamentals of physical-layer wireless and mobile communications engineering that are important for the design of any wireless system. This book differs from others in the field by stressing mathematical modeling and analysis. It includes many detailed derivations from first principles, extensive literature references, and provides a level of depth that is necessary for graduate students wishing to pursue research on this topic. The book's focus will benefit students taking formal instruction and practicing engineers who are likely to already have familiarity with the standards and are seeking to increase their knowledge of this important subject. Major changes from the second edition: 1. Updated discussion of wireless standards (Chapter 1). 2. Updated treatment of land mobile radio propagation to include space-time correlation functions, mobile-to-mobile (or vehicle-to-vehicle) channels, multiple-input multiple-output (MIMO) channels, improved simulation models for land mobile radio channels, and 3G cellular simulation models. 3. Updated treatment of modulation techniques and power spectrum to include Nyquist pulse shaping and linearized Gaussian minimum shift keying (LGMSK). 4. Updated treatment of antenna diversity techniques to include optimum combining, non-coherent square-law combining, and classical beamforming. 5. Updated treatment of error control coding to include space-time block codes, the BCJR algorithm, bit interleaved coded modulation, and space-time trellis codes. 6. Updated treatment of spread spectrum to include code division multiple access (CDMA) multi-user detection techniques. 7. A completely new chapter on multi-carrier techniques to include the performance of orthogonal frequency division multiplexing (OFDM) on intersymbol interference (ISI) channels, OFDM residual ISI cancellation, single-carrier frequency domain equalization (SC-FDE), orthogonal frequency division multiple access (OFDMA) and single-carrier frequency division multiple access (SC-FDMA). 8.

Описание: The book provides a comprehensive investigation of the performance and problems of the TCP/IP protocol stack, when data is transmitted over GSM, GPRS and UMTS. It gives an introduction to the protocols used for Internet access today, and also the Wireless Application Protocol (WAP). The basics of GSM, GPRS and UMTS are given, which are necessary for understanding the main topic, TCP performance over GSM, GPRS and UMTS. We describe at length the problems that TCP has when operating over a mobile radio link, and what has been proposed to remedy these problems. We derive the optimum TCP packet length for maximum data throughput on wireless networks, analytically and by simulation. Results on the throughput and various other parameters of TCP over mobile networks are given. This book gives valuable advice to network operators and application programmers to maximize data throughput, and which protocols, transmission modes, and coding schemes to use and which to avoid.

Описание: Radio network system planning is a comprehensive optimisation task where different planning targets - coverage, capacity and quality- have a direct influence on each other and where optimised solution is a compromise of these planning areas. In order to find out the cost effective and high quality radio network plan the well-known theoretical details have to be bound with practical radio planning issues like planning phases and planning parameters. At the same time the long-term network evolution paths and the possible changes of the radio propagation environment have to be well understood. Radio Interface System Planning for GSM/GPRS/UMTS introduces the radio system planning where these theoretical and practical details have both been emphasized and then utilized for the planning of GSM, GPRS and UMTS mobile networks. The key planning parameters for these systems are explained and the typical values for power budget, various margins, gains and losses, and frequency reuse are given. Also, the book describes the common tasks in radio system planning. The planning methods and phases introduced in the book can also be applied to other mobile communication systems.
Описание: Offers coverage from both a theoretical and practical perspective on the planning and optimization aspects of UMTS, and a number of other techniques to help operators get the most out of their networks. This book provides an end-to-end perspective, from network design to optimization.
Описание: Providing an accessible introduction to all stages of planning and optimizing UMTS, HSPA, and LTE cellular networks, this book supplies a comprehensive explanation of the fundamental aspects of current and future cellular networks.
