Book Wireless Personal Communications

Download or read book Wireless Personal Communications written by Martin J. Feuerstein and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, the state-of-the-art and future vision of wireless communications is presented in the form of a number of new services. Wireless personal communications is clearly a different service than today's cellular radio or cordless telephone, but there is an evolutionary connection between the three services. This book addresses questions about what features of personal communication services (PCS) will be met by existing or enhanced digital cellular radio technology. The regulatory and standards aspects of wireless communications are currently in a crucial stage of their formulation. A section of the book is devoted to the opinions of representatives from regulatory agencies and standards organizations on the future of this critical area. One of the most intriguing questions about the future of wireless communications has to do with the choice of multiple access technique. The trade offs between time division multiple access (TDMA) and code division multiple access (CDMA) have been the topic of many a heated discussion amongst members of the wireless community. This book presents a thorough discussion of a number of the topics which are instrumental in making a fair comparison of TDMA and CDMA; these topics include: analytical performance evaluation techniques, capacity studies, equalization requirements, and shared spectrum comparisons. Many of the technologies associated with wireless personal communications are reaching the design stages. This book presents a number of alternatives for designs of both base stations and user terminals. Some of the key questions of equalization, control channel requirements, multi-path diversity and channel allocation strategies have been addressed. Invariably, system designs and performance are tied to the characteristics of the radio channel. This book introduces several novel techniques for predicting propagation and system performance in a variety of indoor and outdoor environments. These techniques include analytical as well as computer simulation algorithms for predicting signal strenghts and other channel parameters based on the local topographical features. This book serves as an excellent reference source and may be used as a text for advanced courses on wireless communications, cellular radio, or digital mobile radio.

Book Channel Equalization for Wireless Communications

Download or read book Channel Equalization for Wireless Communications written by Gregory E. Bottomley and published by John Wiley & Sons. This book was released on 2012-01-03 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most thorough, up-to-date reference on channel equalization—from basic concepts to complex modeling techniques In today's instant-access society, a high premium is placed on information that can be stored and communicated effectively. As a result, storage densities and communications rates are being pushed to capacity, causing information symbols to interfere with one another. To help unclog pathways for the clearer conveyance of information, this book offers in-depth discussion of the significant contributions and future adaptability of channel equalization and a set of approaches for solving the problem of intersymbol interference (ISI). Chapter explorations in Channel Equalization include: Channel equalization topics presented with incremental learning methodology—from the very fundamental concept to more advanced mathematical knowledge Coverage of technology used in second-, third- and fourth-generation cellular communication systems A set of homework problems that reinforce concepts discussed in the book Tutorial explanations of recent developments currently captured in IEEE technical journals Unlike existing digital communications books that devote cursory attention to channel equalization, this invaluable guide addresses a crucial need by focusing solely on the background, current state, and future direction of this increasingly important technology. A unique mix of basic concepts and complex frameworks for delivering digitized data make Channel Equalization a valuable reference for all practicing wireless communication engineers and students dealing with the pressing demands of the information age.

Book Equalization of Time Varying Dispersive Channels Via Sequence Estimation

Download or read book Equalization of Time Varying Dispersive Channels Via Sequence Estimation written by R. Ibaraki and published by . This book was released on 1983 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adaptive maximum likelihood sequence estimation (AMLSE) has been shown to be an effective mitigation technique for high data rate links against the deleterious effects of intersymbol interference resulting from rapidly time-varying and frequency selective fading channels. It was demonstrated that significant performance improvements can be obtained through the use of AMLSE receiver demodulation in comparison to conventional (non-delay spread specialized) receivers and even decision feedback equalization receivers. In addition, several important channel related receiver anomalies which introduce symbol timing ambiguities were identified.

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.

Book Maximum Likelihood Sequence Estimation for Unknown Dispersive and Time Variant Communication Channels

Download or read book Maximum Likelihood Sequence Estimation for Unknown Dispersive and Time Variant Communication Channels written by L. E. Hoff and published by . This book was released on 1981 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Maximum Likelihood Sequence Estimation (MLSE) algorithm is one of a number of techniques developed for processing signals with intersymbol interference. The MLSE algorithm is optimum in the sense that it minimizes the probability of error. This report describes the intuitive and mathematical basis for the MLSE algorithm. The derivation assumes the channel is known and time invariant. In Navy communications (underwater acoustic and hf radio channel) channel characteristics are unknown to the receiver. This study's approach to the problem is to attach to the transmitted message a preamble consisting of a known bit sequence. The receiver uses it to estimate channel response. The MLSE algorithm is applied to the received data using the estimated channel response in lieu of the actual. Performance is then compared under ideal (known channel characteristics) and realistic (estimated channel characteristics) conditions, as a test on the effectiveness of the channel estimation procedure. This approach can be extended to channels exhibiting time variations. Updates to the matched filter and metrics are performed so that the channel distortion is more precisely represented by the estimated encoding. This is done periodically by injecting a short, known sequence into the message stream. The adaptive MLSE algorithm was tested on signals recorded during an hf field test.
