This book was released on 2006-04-18 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: th The papers appearing in this book were originally presented at the 9 Virginia Tech/MPRG Symposium on Wireless Personal Communications. The Symposium on Wireless Communications, which is an annual event for Virginia Tech, was held on June 2-4, 1999. The 1999 symposium was co-sponsored by MPRG, the Division of Continuing Education, University International Programs, and the MPRG Industrial Affiliate Sponsors. Much of the success of our annual symposium, as well as the success of MPRG's research program, is due to the support of our industrial affiliates. Their support allows us to serve the wireless community through research, education and outreach programs. At the time of the 1999 symposium, the MPRG affiliates program included the following organizations: Army Research Office, AT&T Corporation, Bellsouth Cellular Corporation, Comcast Cellular Communications, Inc. , Datum, Inc. , Ericsson, Inc. , Grayson Wireless, Hewlett-Packard Company, Honeywell, Inc. , Hughes Electronics Corporation, ITT Industries, Lucent Technologies, Motorola, National Semiconductor, Nokia, Nortel Networks, Qualcomm, Inc. , Radix Technologies, Inc. , Salient 3 Communications, Samsung Advanced Institute of Technology, Southwestern Bell, Tantivy Communications, Tektronix, Inc. , Telcordia Technologies, Texas Instruments, TRW, Inc. , and the Watkins-Johnson Company As can be seen from the Table of Contents, the papers included in this book are divided into six sections. The first five of these correspond to symposium sessions, and cover the following topics: Propagation and Channel Modeling (4 papers), Antennas (6 papers), Multiuser Detection (3 papers), Radio Systems and Technology (4 papers), and Wireless Data (3 papers).

Book excerpt: In this thesis, combined power and rate adaptations in the reverse channel of a multicell CDMA cellular system over a Nakagami-Lognormal frequency selective fading channel are considered. Imperfect power control, user traffic distribution, Intracell interference, co-channel interference, a RAKE receiver and spatial diversity are also considered. Numerical results obtained by Monte Carlo simulation show that power and rate adaptations result in an increase of the system capacity and prolong the mobile station's battery life.

Download or read book Effects of Base Station Power Control and Soft Handoff on the Outage and Capacity in the Forward Link of CDMA Systems written by Dongdong Li and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on the capacity analysis of the forward link of code division multiple access (CDMA) systems by characterizing the base station (BS) power distribution. With the rapid growth of data and multi-media traffic; the forward link becomes the system bottleneck. How to design an efficient call admission algorithm in the forward link to effectively use the limited base station power while guaranteeing certain quality of service is important to increase the forward link capacity. To effectively use the limited BS power, we need to understand the BS power distribution given a certain traffic pattern. However, the characterization of the BS power in the forward link has not been adequately addressed in the literature and the limit of the BS power on the capacity has not been fully studied. By taking into consideration of channel characteristics and system parameters, such as the network traffic pattern, call admission algorithm, power control strategies, and soft handoff approach, we characterize the BS power distribution and obtain a closed-form expression of the forward link capacity. Furthermore, previous work studying the forward link performance assumes equal BS power throughout the system and obtains a static capacity without considering the correlation and interactional relation among BS powers, which is rarely true in the real CDMA systems. By further considering the interaction among BS powers, we introduce an iterative process to determine the dynamic forward link capacity. From the system engineering aspects, our research can provide an analytical framework to facilitate the design and benchmark of CDMA networks compared to pure computer simulations. The models established in our research also provide an accurate estimation of the network capacity. Since the air interface of future networks or networks being deployed recently, such as wide-band CDMA (WCDMA), CDMA 2000, and Universal Mobile Telecommunication Services (UMTS), is CDMA based, we are expecting that our research is useful to design call admission algorithms in wireless systems.
Download or read book On the Capacity of a Cellular CDMA System Reverse Channel written by Petros Klitorakis and published by . This book was released on 2002-03 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, the reverse channel model for a seven-cell cluster DS-CDMA cellular communications system operating in a slow-flat Nakagami fading and lognormal shadowing environment is developed. The aforementioned system uses imperfect power control to combat the near-far effect and the lognormal shadowing. Forward error correction is applied by using convolutional encoding and soft decision decoding. The probability of bit error is estimated by using a Gaussian approximation, sectoring antennas and a rake receiver at the base station in order to enhance the system's performance. The performance of the system is examined under several values of the standard deviation of lognormal shadowing and the power control error for various numbers of users and values of the Nakagami-m variable by using simulations. Finally, a barrage noise jammer will be introduced and its effect seen in the performance of the cellular communication system for a specific value of E(sub b)/N(sub o).
