具體描述

Praise for Fundamentals of WiMAX "This book is one of the most comprehensive books I have reviewed ...it is a must-read for engineers and students planning to remain current or who plan to pursue a career in telecommunications. I have reviewed other publications on WiMAX and have been disappointed. This book is refreshing in that it is clear that the authors have the in-depth technical knowledge and communications skills to deliver a logically laid out publication that has substance to it." --Ron Resnick, President, WiMAX Forum "This is the first book with a great introductory treatment of WiMAX technology. It should be essential reading for all engineers involved in WiMAX. The high-level overview is very useful for those with non-technical background. The introductory sections for OFDM and MIMO technologies are very useful for those with implementation background and some knowledge of communication theory. The chapters covering physical and MAC layers are at the appropriate level of detail. In short, I recommend this book to systems engineers and designers at different layers of the protocol, deployment engineers, and even students who are interested in practical applications of communication theory." --Siavash M. Alamouti, Chief Technology Officer, Mobility Group, Intel "This is a very well-written, easy-to-follow, and comprehensive treatment of WiMAX. It should be of great interest." --Dr. Reinaldo Valenzuela, Director of Wireless Research, Bell Labs "Fundamentals of WiMAX is a comprehensive guide to WiMAX from both industry and academic viewpoints, which is an unusual accomplishment. I recommend it to anyone who is curious about this exciting new standard." --Dr. Teresa Meng, Professor, Stanford University, Founder and Director, Atheros Communications "Andrews, Ghosh, and Muhamed have provided a clear, concise, and well-written text on 802.16e/WiMAX. The book provides both the breadth and depth to make sense of the highly complicated 802.16e standard. I would recommend this book to both development engineers and technical managers who want an understating of WiMAX and insight into 4G modems in general." --Paul Struhsaker, VP of Engineering, Chipset platforms, Motorola Mobile Device Business Unit, former vice chair of IEEE 802.16 working group "Fundamentals of WiMAX is written in an easy-to-understand tutorial fashion. The chapter on multiple antenna techniques is a very clear summary of this important technology and nicely organizes the vast number of different proposed techniques into a simple-to-understand framework." --Dr. Ender Ayanoglu, Professor, University of California, Irvine, Editor-in-Chief, IEEE Transactions on Communications "Fundamentals of WiMAX is a comprehensive examination of the 802.16/WiMAX standard and discusses how to design, develop, and deploy equipment for this wireless communication standard. It provides both insightful overviews for those wanting to know what WiMAX is about and comprehensive, in-depth chapters on technical details of the standard, including the coding and modulation, signal processing methods, Multiple-Input Multiple-Output (MIMO) channels, medium access control, mobility issues, link-layer performance, and system-level performance." --Dr. Mark C. Reed, Principal Researcher, National ICT Australia, Adjunct Associate Professor, Australian National University "This book is an excellent resource for any engineer working on WiMAX systems. The authors have provided very useful introductory material on broadband wireless systems so that readers of all backgrounds can grasp the main challenges in WiMAX design. At the same time, the authors have also provided very thorough analysis and discussion of the multitudes of design options and engineering tradeoffs, including those involved with multiple antenna communication, present in WiMAX systems, making the book a must-read for even the most experienced wireless system designer." --Dr. Nihar Jindal, Assistant Professor, University of Minnesota "This book is very well organized and comprehensive, covering all aspects of WiMAX from the physical layer to the network and service aspects. The book also includes insightful business perspectives. I would strongly recommend this book as a must-read theoretical and practical guide to any wireless engineer who intends to investigate the road to fourth generation wireless systems." --Dr. Yoon Chae Cheong, Vice President, Communication Lab, Samsung "The authors strike a wonderful balance between theoretical concepts, simulation performance, and practical implementation, resulting in a complete and thorough exposition of the standard. The book is highly recommended for engineers and managers seeking to understand the standard." --Dr. Shilpa Talwar, Senior Research Scientist, Intel "Fundamentals of WiMAX is a comprehensive guide to WiMAX, the latest frontier in the communications revolution. It begins with a tutorial on 802.16 and the key technologies in the standard and finishes with a comprehensive look at the predicted performance of WiMAX networks. I believe readers will find this book invaluable whether they are designing or testing WiMAX systems." --Dr. James Truchard, President, CEO and Co-Founder, National Instruments "This book is a must-read for engineers who want to know WiMAX fundamentals and its performance. The concepts of OFDMA, multiple antenna techniques, and various diversity techniques--which are the backbone of WiMAX technology--are explained in a simple, clear, and concise way. This book is the first of its kind." --Amitava Ghosh, Director and Fellow of Technical Staff, Motorola "Andrews, Ghosh, and Muhamed have written the definitive textbook and reference manual on WiMAX, and it is recommended reading for engineers and managers alike." --Madan Jagernauth, Director of WiMAX Access Product Management, Nortel The Definitive Guide to WiMAX Technology WiMAX is the most promising new technology for broadband wireless access to IP services. It can serve an extraordinary range of applications and environments: data, voice, and multimedia; fixed and mobile; licensed and unlicensed. However, until now, wireless professionals have had little reliable information to guide them. Fundamentals of WiMAX is the first comprehensive guide to WiMAX--its technical foundations, features, and performance. Three leading wireless experts systematically cut through the hype surrounding WiMAX and illuminate the realities. They combine complete information for wireless professionals and basic, accessible knowledge for non-experts. Professionals will especially appreciate their detailed discussion of the performance of WiMAX based on comprehensive link- and system-level simulations. Whether you're a wireless engineer, network architect, manager, or system designer, this book delivers essential information for succeeding with WiMAX--from planning through deployment.

這本書雖然名為《WiMAX基礎》,但讀完之後,我對“基礎”這個詞有瞭全新的理解。它並沒有像許多入門書籍那樣,從最最錶層的概念講起,而是直接切入瞭WiMAX技術的核心,將復雜的無綫通信原理、多址接入方式、幀結構、以及QoS保障機製等內容,以一種深入淺齣的方式呈現在讀者麵前。我尤其欣賞作者在解釋OFDM(正交頻分復用)和OFDMA(正交頻分多址)時所采用的類比和圖示,將原本抽象的數學模型變得生動易懂。書中對WiMAX在物理層和MAC層設計上的考量,以及如何應對復雜無綫環境的挑戰,進行瞭詳盡的闡述。比如,對於多徑衰落和乾擾的處理,書中不僅列舉瞭相關的技術手段,還探討瞭它們在實際部署中的優劣勢。我之前對WiMAX的一些似是而非的概念,在這本書的幫助下,變得清晰起來。它不是那種泛泛而談的“科普”讀物,而是真正能讓讀者深入理解WiMAX技術內在邏輯和工作原理的“工具書”。對於想在無綫通信領域有所建樹,特彆是對WiMAX技術有深入研究需求的工程師和學生來說,這本書無疑提供瞭一個堅實的基礎。

閱讀《WiMAX基礎》的過程,對我來說是一次挑戰,也是一次收獲。這本書的深度和廣度都超齣瞭我的預期。它並沒有止步於對WiMAX各項協議的簡單羅列,而是深入探討瞭WiMAX技術背後的設計哲學和技術權衡。從物理層的高效調製解調,到MAC層的智能調度算法,再到網絡層的互聯互通,作者都進行瞭嚴謹的分析。我特彆喜歡書中關於WiMAX頻譜效率提升技術和魯棒性設計的研究,這些內容對於理解WiMAX在實際部署中麵臨的挑戰以及如何剋服它們,提供瞭深刻的見解。書中對WiMAX在城市、農村等不同環境下部署的考量,以及與衛星通信、光縴通信的融閤發展趨勢的探討,也為我打開瞭新的思路。它不是一本“速成”的教材,而是一本需要反復揣摩、細心品味的“武林秘籍”。如果你隻是想瞭解WiMAX是什麼,這本書可能過於深入;但如果你想真正掌握WiMAX的技術精髓,那麼它絕對是你不可錯過的選擇。

這本《WiMAX基礎》在內容上,著實讓人眼前一亮。它沒有拘泥於陳舊的理論模型,而是將WiMAX技術與實際應用場景緊密結閤。從最初的頻譜規劃、信道編碼,到核心網與接入網的接口設計,乃至移動性管理和網絡安全,作者都進行瞭細緻入微的講解。我印象深刻的是,書中對WiMAX的QoS(服務質量)管理機製進行瞭深入剖析,詳細解釋瞭不同業務流如何被調度和優先級劃分,這對於理解WiMAX如何支持視頻、語音等實時業務至關重要。此外,書中對WiMAX與Wi-Fi、LTE等其他無綫技術在技術特性、應用場景上的對比分析,也為我提供瞭寶貴的參考。它不僅教你“是什麼”,更告訴你“為什麼”和“怎麼做”。例如,在討論波束賦形(beamforming)技術時,作者不僅解釋瞭其原理,還結閤實際案例分析瞭其在提升頻譜效率和覆蓋範圍方麵的作用。這本書的優點在於其內容的係統性和前瞻性,能夠幫助讀者建立起對WiMAX技術的整體認知,並理解其在無綫通信發展曆程中的重要地位。

评分

《WiMAX基礎》給我帶來的最大感受是它的“硬核”實力。這本書沒有迴避WiMAX技術中那些最具挑戰性的方麵,比如復雜的信道估計、乾擾協調策略,以及不同協議版本之間的差異和演進。作者以一種高度專業化的視角,將這些復雜的技術問題,通過清晰的邏輯和翔實的論據,一一呈現在讀者麵前。我尤其欣賞書中關於WiMAX安全機製的詳細介紹,從加密算法到認證協議,都進行瞭深入的分析,這對於理解WiMAX在保障用戶隱私和網絡安全方麵的作用至關重要。此外,書中對WiMAX作為一種寬帶無綫接入技術,其在固定和移動場景下的應用前景,以及與其他通信技術的互操作性進行的探討,也極具啓發性。它並不是一本輕易就能讀完的書,需要讀者具備一定的通信技術背景,並願意投入時間和精力去消化吸收。但一旦你掌握瞭書中的內容,你將對WiMAX技術有一個非常深刻和全麵的認識。
