Multi-Carrier Digital Communications

Theory and Applications of OFDM, Second Edition

Multi-carrier modulation, Orthogonal Frequency Division Multiplexing (OFDM) particularly, has been successfully applied to a wide variety of digital communications applications over the past several years. OFDM has been chosen as the physical layer standard for a variety of important systems and its implementation techniques continue to evolve rapidly. This book is a valuable summary of the technology, providing an understanding of new advances as well as the present core technology.

A unified presentation of OFDM performance and implementation over a wide variety of channels, including both wireline and wireless systems, is made. This will prove valuable both to developers of such systems and to researchers and graduate students involved in analysis of digital communications.

In the interest of brevity, the authors have minimized treatment of more general communication issues. There exist many excellent texts on communication theory and technology. Only brief summaries of topics not specific to multi-carrier modulation are presented in this book where essential. As a background, it is assumed that the reader has a clear knowledge of basic fundamentals of digital communications.

Highlights of the Second Edition

During the past few years since the publication of the first edition of this text, the technology and application of OFDM have continued their rapid pace of advancement. As a result, it became clear that a new edition of the text would be highly desirable. The new edition provides the opportunity to make those corrections and clarifications whose need became apparent from continued discussions with many readers. However, the main purpose is to introduce new topics that have come to the forefront during the past few years, and to amplify the treatment of other subject matter.

Because of the particularly rapid development of wireless systems employing OFDM, the authors introduced a section early in the text on wireless channel fundamentals. They have extended and modified their analysis of the effects of clipping, including new simulation results. A section of channel estimation has been added to the chapter on equalization. The chapter on local area networks has been greatly expanded to include the latest technology and applications. Three totally new chapters are added, on OFDM multiple access technology, on ultra wideband technology, and on WiMAX (IEEE 802.16).

Organization of This Book

 

The authors begin with a historical overview of multi-carrier communications, wherein its advantages for transmission over highly dispersive channels have long been recog-nized, particularly before the development of equalization techniques. They then focus on the bandwidth efficient technology of OFDM, in particular the digital signal processing techniques that have made the modulation format practical. Several chapters describe and analyze the sub-systems of an OFDM implementation, such as clipping, synchronization channel estimation, equalization, and coding. Analysis of performance over channels with various impairments is presented.

The book continues with descriptions of three very important and diverse applications of OFDM that have been standardized and are now being deployed. ADSL provides access to digital services at several Mbps over the ordinary wire-pair connection between customers and the local telephone company central office. Digital broadcasting enables the radio reception of high-quality digitized sound and video. A unique configuration that is enabled by OFDM is the simultaneous transmission of identical signals by geographically dispersed transmitters. And, the new development of wireless LANs for multi-Mbps communications is presented in detail. Each of these successful applications required the development of new fundamental technology.

Finally, the book concludes with describing the OFDM based multiple access techniques, ultra wideband technology and WiMAX.

商品描述(中文翻譯)

多載波數位通訊
OFDM的理論與應用,第二版

在過去幾年中,多載波調變,尤其是正交分頻多工(OFDM),已成功應用於各種數位通訊應用。OFDM已被選為多個重要系統的物理層標準,其實現技術仍在快速演進。本書是對這項技術的寶貴總結,提供對新進展以及現有核心技術的理解。

本書統一介紹了OFDM在各種通道上的性能和實現,包括有線和無線系統。這對於這些系統的開發者以及從事數位通訊分析的研究人員和研究生都非常有價值。

為了簡潔起見,作者將一般通訊問題的處理最小化。有許多優秀的通訊理論和技術的書籍。本書僅對與多載波調變無關的主題進行簡要概述。作為背景,假設讀者對數位通訊的基本原理有清晰的了解。

第二版的亮點

自本書第一版出版以來的幾年中,OFDM的技術和應用持續快速發展。因此,明顯需要一個新版。新版提供了機會,對持續與許多讀者進行討論後明顯需要修正和澄清的內容進行修改。然而,主要目的是介紹在過去幾年中嶄露頭角的新主題,並加強其他主題的處理。

由於使用OFDM的無線系統特別快速發展,作者在本書早期引入了一節關於無線通道基礎的內容。他們擴展並修改了對剪切效應的分析,包括新的模擬結果。在等化章節中增加了一節關於通道估計的內容。局域網的章節大幅擴展,包括最新的技術和應用。新增了三個全新的章節,分別介紹了OFDM多重接入技術、超寬頻技術和WiMAX(IEEE 802.16)。

本書組織結構

作者首先對多載波通訊進行了歷史概述,其中長期以來已經認識到它在高度色散通道上的優勢,尤其是在等化技術發展之前。然後他們專注於OFDM的帶寬效率技術,特別是使調變格式實用的數位信號處理技術。幾個章節描述和分析了OFDM實現的子系統,如剪切、同步通道估計、等化和編碼。還介紹了在各種損壞通道上的性能分析。

本書繼續描述了三個非常重要且多樣化的OFDM應用,這些應用已經標準化並正在部署。ADSL通過普通的電話線對客戶和當地電話公司中央辦公室之間的連接提供數字服務訪問。數字廣播實現了高質量的數字化音頻和視頻的無線接收。OFDM使地理分散的發射器同時傳輸相同信號的獨特配置成為可能。還詳細介紹了無線局域網的新發展,用於多Mbps通信。每個成功的應用都有詳細的描述。
