| السلام عليكم اخي لقد نقلت لك بعض الكتب عسى ان تكون هي التي تبحث عنها او تساعدك تقنية اتصالات الراديو الرقمية Digital Synthesizers and Transmitters for Software Radio Jouko Vankka, "Digital Synthesizers and Transmitters for Software Radio" Springer | ISBN 1402031947 | 2005 Year | PDF | 12 Mb | 359 Pages The approach adopted in Digital Synthesizers and Transmitters for Software Radio will provide an understanding of key areas in the field of digital synthesizers and transmitters. It is easy to include different digital techniques in the digital synthesizers and transmitters by using digital signal processing methods, because the signal is in digital form. By programming the digital synthesizers and transmitters, adaptive channel bandwidths, modulation formats, frequency hopping and data rates are easily achieved. Techniques such as digital predistortion for power amplifier linearization, digital compensation methods for analog I/Q modulator nonlinearities and digital power control and ramping are presented in this book. The flexibility of the digital synthesizers and transmitters makes them ideal as signal generators for software radio. Software radios represent a major change in the design paradigm for radios in which a large portion of the functionality is implemented through programmable signal processing devices, giving the radio the ability to change its operating parameters to accommodate new features and capabilities. A software radio approach reduces the content of radio frequency (RF) and other analog components of traditional radios and emphasizes digital signal processing to enhance overall transmitter flexibility. Software radios are emerging in commercial and military infrastructure. حمل من هنا: http://rapidshare.de/files/11001998/JVankka.rar.html Password: color=#247cd4www.AvaxHome.ru ************************************************** ************************************************ الكتاب الثانى Digital Modulation Techniques Summary: Book Info Explains the full range of today's digital modulation techniques and their practical application to conventional, fixed microwave terrestrial communications, satellite communications, mobile wireless, mobile satellite, and fiber-optic communications. http://rapidshare.de/files/7833331/A...s_MAZ.rar.html ************************************************** **************************************** الكتاب الثالث Digital Communication over Fading Channels (Wiley Series in Telecommunications and Signal Processing) Summary: The four short years since Digital Communication over Fading Channels became an instant classic have seen a virtual explosion of significant new work on the subject, both by the authors and by numerous researchers around the world. Foremost among these is a great deal of progress in the area of transmit diversity and space-time coding and the associated multiple input-multiple output (MIMO) channel. This new edition gathers these and other results, previously scattered throughout numerous publications, into a single convenient and informative volume. Like its predecessor, this Second Edition discusses in detail coherent and noncoherent communication systems as well as a large variety of fading channel models typical of communication links found in the real world. Coverage includes single- and multichannel reception and, in the case of the latter, a large variety of diversity types. The moment generating function (MGF)-based approach for performance analysis, introduced by the authors in the first edition and referred to in literally hundreds of publications, still represents the backbone of the book's presentation. Important features of this new edition include: An all-new, comprehensive chapter on transmit diversity, space-time coding, and the MIMO channel, focusing on performance evaluation[*] Coverage of new and improved diversity schemes[*] Performance analyses of previously known schemes in new and different fading scenarios[*] A new chapter on the outage probability of cellular mobile radio systems[*] A new chapter on the capacity of fading channels[*] And much more Digital Communication over Fading Channels, Second Edition is an indispensable resource for graduate students, researchers investigating these systems, and practicing engineers responsible for evaluating their performance. الرابط http://rapidshare.de/files/13512109/...649538.pdf.rar PASSWORD: color=#247cd4ed@board ************************************************** ************************************************* الكتاب الرابع كتاب CDMA Systems Capacity Engineering - Artech House This hands-on practical book tackles CDMA (code division multiple access) capacity engineering, which is crucial to ensuring optimal performance of wireless networks. Examining CDMA capacity at all system levels, this book shows network engineers and operators how to quantify systems capacity so they can design resource management and capacity strategies. It analyzes various critical systems conditions, such as system outages, so CDMA capacity can be properly managed. Case studies and detailed operations scenarios provide practical insight for capacity planing and resource allocation to ensure optimal network performance. Because of the key role CDMA plays in current and third generation cellular systems, this book is also an essential reference for wireless network researchers and planners. A full range of analytic methods for voice, data, and multimedia make this book an indispensable tool for optimizing CDMA systems حمل من هنا : http://www.megaupload.com/?d=KLIZ0REW Password : color=#247cd4www.blueportal.org ************************************************** ************************************************** ******* الكتاب الخامس اقدم اليكم هذا الكتاب المفيد جدا وارجو ان ينال قبولكم Description Taking a close look at an integral part of next generation wireless communications, this book presents SS/CDMA system architecture (Satellite Switched Code Division Multiple Access) and its various communications services.
