Download or read book Code Division Multiple Access CDMA written by R. Michael Buehrer and published by Morgan & Claypool Publishers. This book was released on 2006 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the basic aspects of Code Division Multiple Access or CDMA. It begins with an introduction to the basic ideas behind fixed and random access systems in order to demonstrate the difference between CDMA and the more widely understood TDMA, FDMA or CSMA. Secondly, a review of basic spread spectrum techniques are presented which are used in CDMA systems including direct sequence, frequency-hopping and time-hopping approaches. The basic concept of CDMA is presented, followed by the four basic principles of CDMA systems that impact their performance: interference averaging, universal frequency reuse, soft handoff, and statistical multiplexing. The focus of the discussion will then shift to applications. The most common application of CDMA currently is cellular systems. A detailed discussion on cellular voice systems based on CDMA, specifically IS-95, is presented. The capacity of such systems will be examined as well as performance enhancement techniques such as coding and spatial filtering. Also discussed are Third Generation CDMA cellular systems and how they differ from Second Generation systems. A second application of CDMA that is covered is spread spectrum packet radio networks. Finally, there is an examination of multi-user detection and interference cancellation and how such techniques impact CDMA networks. This book should be of interest and value to engineers, advanced students, and researchers in communications.

Download or read book Performance Analysis of a DS CDMA System Carrying Multirate Traffic with RCMA Protocol written by Rey Fredy González May and published by . This book was released on 2001 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, users need to have a communication service that allows them integrate voice and data, plus mobility. Cellular communication needs to be improved in its data transmission in order to be a reliable and competitive service as the wire service does. In this work, we evaluate Reservation Code Multiple Access (RCMA) to integrate services in a DS-CDMA cellular system carrying multirate traffic, voice and a data types. The multiuser interfer- ence factor, the probability of a successful transmission given other users are transmitting, and an homogeneous transmission line rate are considered in the analysis. We obtain the capacity of the number of users supported in function of the user type with the highest service quality. We evaluate the system performance in terms of speech packets dropping probability, message loss probability and data packet average delay. We conclude that CDMA system capacity is improved if RCMA is used to control the access medium and it depends of the service quality to provide.
Download or read book Mobile Multimedia Communications written by David J. Goodman and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1997, the two hottest topics in information technology are the Internet and mobile communications. Each one has the enthusiastic attention of the consuming public, investors. and the technical community. In a time of rapid expansion, they both face technical obstacles to meeting the public's high expectations. This situation stimulates a high volume of research in both areas. To bring the Internet into the twenty-first century. the research community focuses on multimedia communications in which integrated systems store, transport. and process many types of information simultaneously. A major challenge is to meet the of each information service. This problem is separate performance requirements especially challenging when a system has to deliver broadband, real-time services such as full-motion video. Meanwhile. the mobile communications research community continues its long term struggle against the triple challenge of mobility. ether. and energy. "Mobility" refers to the changing locations of terminals. When terminals are mobile. networks have to determine their locations and dynamically establish routes for information. The networks also have to rearrange themselves in order to maintain links to terminals with active communications sessions. "Ether" refers to the problems of wireless communications including limited bandwidth. rapidly changing radio propagation conditions. mutual interference of radio signals. and vulnerability of systems to eavesdropping and unauthorized access. "Energy" refers to the fact that portable information devices carry their own power sources. The rate at which the batteries of cellular telephones and portable computers drain their energy has a strong effect on their utility.

Download or read book Adaptation and Cross Layer Design in Wireless Networks written by Mohamed Ibnkahla and published by CRC Press. This book was released on 2018-10-08 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adaptive techniques play a key role in modern wireless communication systems. The concept of adaptation is emphasized in the Adaptation in Wireless Communications Series through a unified framework across all layers of the wireless protocol stack ranging from the physical layer to the application layer, and from cellular systems to next-generation wireless networks. Adaptation and Cross Layer Design in Wireless Networks is devoted to adaptation in the data link layer, network layer, and application layer. The book presents state-of-the-art adaptation techniques and methodologies, including cross-layer adaptation, joint signal processing, coding and networking, selfishness in mobile ad hoc networks, cooperative and opportunistic protocols, adaptation techniques for multimedia support, self –organizing routing, and tunable security services. It presents several new theoretical paradigms and analytical findings which are supported with various simulation and experimental results. Adaptation in wireless communications is needed in order to achieve high capacity and ubiquitous communications. The current trend in wireless communication systems is to make adaptation dependent upon the state of the relevant parameters in all layers of the system. Focusing on simplified cross layer design approaches, this volume describes advanced techniques such as adaptive resource management, adaptive modulation and coding, 4G communications, QoS, diversity combining, and energy and mobility aware MAC protocols. The first volume in the series, Adaptive Signal Processing in Wireless Communications (cat no.46012) covers adaptive signal processing at the physical layer.

This book was released on 2002-09-18 with total page 824 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers comprising Vol. I and Vol. II were prepared for and presented at the International Conference on Information Networking 2002 (ICOIN 2002), which was held from January 30 to February 1, 2002 at Cheju Island, Korea. It was organized by the KISS (Korean Information Science Society) SIGIN in Korea, IPSJ SIG DPE (Distributed Processing Systems) in Japan, the ITRI (Industrial Technology Research Institute), and National Taiwan University in Taiwan. The papers were selected through two steps, refereeing and presentation review. We selected for the theme of the conference the motto “One World of Information Networking”. We did this because we believe that networking will transform the world into one zone, in spite of different ages, countries and societies. Networking is in the main stream of everyday life and affects directly millions of people around the world. We are in an era of tremendous excitement for professionals working in many aspects of the converging networking, information retailing, entertainment, and publishing companies. Ubiquitous communication and computing technologies are changing the world. Online communities, e commerce, e service, and distance learning are a few of the consequences of these technologies, and advanced networking will develop new applications and technologies with global impact. The goal is the creation of a world wide distributed computing system that connects people and appliances through wireless and high bandwidth wired channels with a backbone of computers that serve as databases and object servers. Thus, Vol.
