Available in PDF, EPUB and Kindle. Book excerpt: Although it is well known that the reverse link coverage of a cell has an inverse relationship with the user capacity in a Code Division Multiple Access (CDMA) cellular system, our literature review has found only one published paper that analyzes this important issue and provides some quantitative results. An accurate prediction of cell coverage as a function of user capacity is essential in CDMA network design and deployment, and is therefore of great interest. The results presented by the previous research are based on only one possible approach. Because CDMA is the primary technology being developed for 3G systems, there is great need and interest in further investigation of this issue. Thus, our research objective is to develop rigorous methods for estimating the coverage vs. capacity tradeoff in the reverse link of CDMA cellular systems and to then predict average reverse link coverage. In this dissertation, we first review the basics of mobile communication and CDMA cellular systems. We then describe the instantaneous outage approach used in the previous work to derive the relationship between cell coverage and capacity in a CDMA system and we analyze some of the limitations of this approach. Using this foundation, we develop a theoretical framework to analyze the coverage vs. capacity tradeoff and estimate the reverse-link single-cell coverage for CDMA cellular networks based on a duration outage criterion. We also analyze the impact of multipath fading on the CDMA cell coverage estimates. In addition to single-cell coverage, we also analyze reverse-link two-cell coverage including the impact of soft handoff. Based on this, we also analyze the tradeoff between capacity improvement vs. coverage expansion due to soft handoff. Further, we describe a simple algorithm for designing multi-cell coverage that is useful for planning the topology of a CDMA cell networks. In total, the results of this research provide a comprehensive framework for designing the topology of CDMA cell networks to achieve specific coverage and capacity requirements. Finally, we extend our coverage vs. capacity analysis to include multi-rate services allowed by wideband CDMA cellular systems.

Book excerpt: Most research on capacity analysis of code division multiple access (CDMA) cellular systems is based on the assumption that all cells have a fixed number of mobile users. Since real traffic load changes from cell to cell, such a capacity is only a special case in mobile cellular networks. The capacity of a CDMA system is mainly determined by the total interference introduced by the mobiles in the same frequency bandwidth. In this thesis, we first analyse this cochannel interference. Statistical characteristics of the interference are given by theoretical analysis and computer simulation. A method based on the system state, interference coefficients, propagation model and link quality is proposed to calculate reverse link capacity of a CDMA system with non-uniform traffic load. The effects of various factors, such as link quality requirement, propagation parameters (shadow fading deviation [sigma], path loss exponent _), voice activity, and other cell traffic load on capacity, are investigated based on two different simulation models. The numerical results for different propagation parameters and link quality requirements are presented and discussed. (Abstract shortened by UMI.).

This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, we propose, analyze and assess three novel radio channel access techniques to effectively manage the interference in the reverse links of a cellular CDMA network with the emphasis on the packet data applications. The first scheme is based on the combined use of rate, power and cell control, whereby base station receivers attempt to operate with equal receive power. In the second approach, the temporal variations of the channels are exploited to schedule packet-transmissions in different modes of operations. The third technique uses the overlapping sectors for adaptive sectoring of a cell based on the non-uniform angular traffic around the base stations. All of these approaches are systematically developed based on the fact that both the interference-reduction and the interference-balancing improve the CDMA system performance. The techniques in effect implement interference control at the system level respectively (a) exploiting the source characteristics of the mobiles for network-wide interference-balancing, (b) time separating the signals based on the relative channel conditions and delaying dominant interferers and (c) jointly selecting the best possible set of antenna based on the angular traffic at the antenna and making the user assignment that minimizes the total transmit power. Algorithms for base station selection, transmission rate adjustment and mobile power adaptation for the above schemes are also discussed. Simulation results and numerical examples that compare ours with previously reported techniques demonstrate the effectiveness of the new techniques.

Download or read book Call Admission Control in Mobile Cellular Networks written by Sanchita Ghosh and published by Springer. This book was released on 2012-08-14 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Call Admission Control (CAC) and Dynamic Channel Assignments (DCA) are important decision-making problems in mobile cellular communication systems. Current research in mobile communication considers them as two independent problems, although the former greatly depends on the resulting free channels obtained as the outcome of the latter. This book provides a solution to the CAC problem, considering DCA as an integral part of decision-making for call admission. Further, current technical resources ignore movement issues of mobile stations and fluctuation in network load (incoming calls) in the control strategy used for call admission. In addition, the present techniques on call admission offers solution globally for the entire network, instead of considering the cells independently. CAC here has been formulated by two alternative approaches. The first approach aimed at handling the uncertainty in the CAC problem by employing fuzzy comparators. The second approach is concerned with formulation of CAC as an optimization problem to minimize call drop, satisfying a set of constraints on feasibility and availability of channels, hotness of cells, and velocity and angular displacement of mobile stations. Evolutionary techniques, including Genetic Algorithm and Biogeography Based Optimization, have been employed to solve the optimization problems. The proposed approaches outperform traditional methods with respect to grade and quality of services.

This book was released on 2013-04-17 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Third generation networks have been specified and are now being deployed in a few countries. They are expected to reach maturity in the next several years and to provide various services including audio, video, and world wide web browsing. Furthermore, radio terminals are expected to be integrated in a number of devices such as personal computers, personal digital assistants, and even television sets. Such a wide-usage of radio mandates ongoing research to address design of networks with high capacity while providing acceptable quality of service. This volume is the sixth in the edited series Multiaccess, Mobility and Teletraffic for Wireless Communications. It presents the selected papers for the proceedings of the Seventh Workshop (MMT'2002) held on this topic in June 2002 in Rennes, France. The aim of this workshop has been to address a set of important issues of interest to the wireless communications community. In particular, the focus of this workshop is to identify, present and discuss the theoretical and implementation issues critical to the design of land based mobile cellular and microcellular as well as wireless local area networks. Included in this book are recent research results on performance analysis of wireless packet networks, channel coding and receiver design, radio resource management in third generation systems, mobility management in cellular and mobile IP networks, performance of transport protocols (TCP) over radio link control protocols, and ad-hoc networks.
