Book Design and Performance Analysis of Multicarrier CDMA Systems

Available in PDF, EPUB and Kindle. Book excerpt: The research being conducted is designed to yield major improvements in the capabilities of military wireless communications systems. The new system is designed around a physical layer based upon a wideband direct sequence (DS) multicarrier (MC) code division multiple access (CDMA) link. Among other things, an MC signal does not require a contiguous spectrum: this means, for example. that an MC CDMA network can be overlaid upon an existing set of narrowband signals simply by leaving appropriate gaps in the placement of the multiple carriers. Such a characteristic will allow the military to employ the same frequencies as used by various commercial systems, thereby making use of the technology advancements in those frequency bands, and yet not be limited in deployment because of excessive interference from conventional narrowband signals. We have emphasized the effect of estimation errors in determining channel state information for use in optimal receiver design for MC CDMA systems, and have performed analyses of performance. as measured by the average probability of error of the system. We have also included the use of space-time spreading.

Book A Bi Level FH CDMA for Wireless Communication Over Fading Channels

Download or read book A Bi Level FH CDMA for Wireless Communication Over Fading Channels written by Y.V.S. Durga Prasad and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A Bi-level Frequency Hopping Code-Division Multiple-Access (FH-CDMA)" scheme for wireless communication systems is developed. This new scheme provides flexibility in the selection of modulation codes and FH patterns. By partitioning modulation codes, our Bi-Level FH-CDMA scheme can be modified to support more possible users without increasing the number of FH patterns. This scheme is applied for different Fading channels and their performances in terms of Bit Error probability (BEP) are compared. We also calculate Spectral Efficiency (SE) of this scheme and compare this with Spectral Efficiency (SE) of Goodman's Frequency-Shift-Keying FH-CDMA. Our results show that the partitioned Two-Level FH-CDMA scheme supports higher data rate and greater SE than Goodman's Frequency-Shift-Keying FH-CDMA scheme under some conditions.

Book Principles of Mobile Communication

Download or read book Principles of Mobile Communication written by Gordon L. Stüber and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 670 pages. Available in PDF, EPUB and Kindle. Book excerpt: Principles of Mobile Communication provides an authoritative treatment of the fundamentals of mobile communications, one of the fastest growing areas of the modern telecommunications industry. The book stresses the fundamentals of mobile communications engineering that are important for the design of any mobile system. Less emphasis is placed on the description of existing and proposed wireless standards. This focus on fundamental issues should be of benefit not only to students taking formal instruction but also to practising engineers who are likely to already have a detailed familiarity with the standards and are seeking to deepen their knowledge of this important field. The book stresses mathematical modeling and analysis, rather than providing a qualitative overview. It has been specifically developed as a textbook for graduate level instruction and a reference book for practising engineers and those seeking to pursue research in the area. The book contains sufficient background material for the novice, yet enough advanced material for a sequence of graduate level courses. Principles of Mobile Communication treats a variety of contemporary issues, many of which have been treated before only in the journals. Some material in the book has never appeared before in the literature. The book provides an up-to-date treatment of the subject area at a level of detail that is not available in other books. Also, the book is unique in that the whole range of topics covered is not presently available in any other book. Throughout the book, detailed derivations are provided and extensive references to the literature are made. This is of value to the reader wishing to gain detailed knowledge of a particular topic.
