Book Performance Analysis of a DS CDMA System Carrying Multirate Traffic with RCMA Protocol

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.

Book Performance Analysis of Pilot Aided Forward CDMA Cellular Channel

Download or read book Performance Analysis of Pilot Aided Forward CDMA Cellular Channel written by Nikolaos Panagopoulos and published by . This book was released on 2001-09-01 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis we analyze the performance of the forward channel of a DS-CDMA cellular system operating in a Rayleigh-fading, Lognormal-shadowing environment. We develop an upper bound on the probability of bit error, including all the participating interference. In addition, various techniques such as sectoring and forward error correction in the terms of convolutional encoding are applied to optimize the performance. We further improve the performance by applying a narrow bandpass filter in the pilot tone branch of the demodulator. We then adjust the bandwidth of the filter in the means of the interference power passing through and observe the effects on the probability of bit error of the system. Moreover, pilot tone power control is added to enhance the demodulation. Finally, in this thesis a simple single cell system functioning as a port-to-port network communication between very small numbers of users is analyzed.

Book Performance Analysis of Multi Channel and Multi Traffic on Wireless Communication Networks

Download or read book Performance Analysis of Multi Channel and Multi Traffic on Wireless Communication Networks written by Wuyi Yue and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the rapidly increasing penetration of laptop computers and mobile phones, which are primarily used by mobile users to access Internet s- vices like e-mail and World Wide Web (WWW) access, support of Internet services in a mobile environment is an emerging requirement. Wireless n- works have been used for communication among fully distributed users in a multimedia environment that has the needs to provide real-time bursty traffic (such as voice or video) and data traffic with excellent reliability and service quality. To satisfy the huge wireless multimedia service demand and improve the system performance, efficient channel access methods and analytical methods must be provided. In this way very accurate models, that faithfully reproduce the stochastic behavior of multimedia wireless communication and computer networks, can be constructed. Most of these system models are discrete-time queueing systems. Queueing networks and Markov chains are commonly used for the p- formance and reliability evaluation of computer, communication, and m- ufacturing systems. Although there are quite a few books on the individual topics of queueing networks and Markov chains, we have found none that covers the topics of discrete-time and continuous-time multichannel mul- traffic queueing networks. On the other hand, the design and development of multichannel mul- hop network systems and interconnected network systems or integrated n- works of multimedia traffic require not only such average performance m- sures as the throughput or packet delay but also higher moments of traffic departures and transmission delay.

Book Wireless Location in CDMA Cellular Radio Systems

Download or read book Wireless Location in CDMA Cellular Radio Systems written by James J. Caffery, Jr. and published by Springer Science & Business Media. This book was released on 2006-01-02 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the increasing market penetration of cellular telephones, the number of E-911 calls placed by cellular telephones has grown cons- erably. This growth in E-911 calls led to a 1996 FCC ruling requiring that all cellular, PCS, and SMR licensees provide location information for the support of E-911 safety services. The provision of such location information is to be implemented in two phases. Phase I, whose deadline has already been passed, requires that wireless carriers relay the caller’s telephone number along with location of the cell site and/or sector se- ing the call, to a designated Public Safety Answering Point (PSAP). This information allows the PSAP to return the call if disconnected. Phase II, to be completed by October 1, 2001, is much more stringent and requires that the location of an E-911 caller be determined and reported with an rms location accuracy of 125 m in 67% of the cases. The applications of wireless location technology extend well beyond E-911 services. Location information can be used by cellular telephone operators themselves for more effective management of their radio - sources, so as to achieve greater spectral efficiencies. Resource m- agement algorithms such as hand-offs between cell sites, channel assi- ments, and others can all benefit from subscriber location information. Location information obtained from vehicular based cellular telephones can be used as an input to Intelligent Transportation Systems (ITS), and in particular traffic management and traveler information systems.
