"Single Carrier FDMA--A New Air Interface for Long Term Evolution" 本书深入探讨了Single Carrier Frequency Division Multiple Access（SC-FDMA）技术，这是一项在移动通信领域，特别是Long Term Evolution（LTE）标准中被广泛采用的新颖空口技术。SC-FDMA的主要优势在于其在频域内的低峰均比（PAPR），这对于提高电池效率和降低发射机复杂性具有重要意义。 SC-FDMA是相对于传统的多载波技术，如Orthogonal Frequency Division Multiplexing (OFDM)的一种优化。在OFDM系统中，由于多个载波的相位和幅度可以独立变化，导致信号的瞬时功率峰值很高，这不仅增加了对发射机线性度的要求，也增大了功耗。相反，SC-FDMA通过单载波传输数据，将数据分配到连续的子载波上，然后在时间上进行多路复用，从而有效地降低了PAPR。书中详细阐述了SC-FDMA的基本原理，包括预编码技术、多址接入方式以及与OFDM系统的比较。读者将了解到如何设计和实现SC-FDMA系统，包括信道编码、调制、多址接入、频率同步和功控策略等方面。此外，书中还可能涵盖了SC-FDMA在实际无线环境中的性能分析，如在衰落信道下的性能、干扰抑制方法以及抗多径衰落的策略。 SC-FDMA的应用不仅限于LTE，它也被考虑在其他无线通信标准中，例如3GPP的LTE-Advanced和WiMAX。书中的内容对于无线通信工程师、研究人员以及对此领域感兴趣的学生来说，提供了理解这项关键技术的理论基础和实践经验。作者Hyung G. Myung和David J. Goodman都是该领域的专家，他们的著作旨在提供一个全面而深入的视角，帮助读者理解SC-FDMA如何改变了无线通信的格局，并推动了移动网络的演进。通过阅读本书，读者能够掌握SC-FDMA的核心概念，以及如何在实际系统设计中应用这些概念，从而更好地适应和引领无线通信技术的发展。

to describe its speciﬁcations: UMTS (Universal Mobile Telecommunica-

of 3GPP speciﬁcations; and UTRAN (Universal Terrestrial Radio Access

Network) refers to the collection of network elements, and their interfaces,

used for transmission between mobile terminals and the network infras-

tructure. The other project, 3GPP2, is concerned with advanced versions

of the original CDMA cellular system. The technologies standardized by

3GPP2 are often referred to collectively as CDMA2000.

The Partnership Projects consist of “organizational partners”, “market

representation partners”, and “individual members”. The organizational

partners are the regional and national standards organizations, listed in Ta-

ble 1.1,based inNorth America, Europe, and Asia. The market representa-

tion partners are industry associations that promote deployment of speciﬁc

technologies. The individual members are companies associated with one

or more of the organizational partners. In October 2006 there were 297

individual members of 3GPP and 82 individual members of 3GPP2.

The technologies embodied in WCDMA and CDMA2000 appear in

hundreds of technical speciﬁcations covering all aspects of a cellular

network. In both Partnership Projects, responsibility for producing the

speciﬁcations is delegated to Technical Speciﬁcation Groups (TSG), each

covering one category of technologies. In 3GPP, the TSGs are further

subdivided into Work Groups (WG). The publication policies of the two

Partnership Projects are different. 3GPP periodically “freezes” a complete

set of standards, including many new speciﬁcations. Each set is referred

to as a “Release”. Each Release is complete in that it incorporates all un-

changed sections of previous standards that are still in effect as well as any

new and changed sections. 3GPP also publishes preliminary speciﬁcations

that will form part of a future Release. By contrast, each TSG in 3GPP2

publishes a new or updated speciﬁcation whenever the speciﬁcation ob-

tains necessary approvals.

Release 5 of WCDMA was frozen in 2002, Release 6 in 2005, and

Release 7 in 2007 [5]. In 2008, LTE speciﬁcations are being ﬁnalized

as Release 8. Two of the innovations in Release 5 are High Speed

Downlink Packet Access (HSDPA) and the IP Multimedia Subsystem

(IMS). In Release 6, the innovations are High Speed Uplink Packet Ac-

cess (HSUPA), the Multimedia Broadcast/Multicast Service (MBMS), and

Wireless LAN/cellular interaction, and in Release 7, Multiple Input

Multiple Output (MIMO) and higher order modulation. Release 8 deliber-

ations focus on the Long Term Evolution (LTE) of WCDMA. In the Radio

Access Network (RAN), the LTE goals are data rates “up to 100 Mbps in

fullmobilitywideareadeploymentsand up to 1 Gbps in lowmobility, local

areadeployments” [6]. Forbest effortpacketcommunication,thelongterm

spectral efﬁciencytargetsare 5–10b/s/Hz in a single (isolated) cell; and up

to 2–3 b/s/Hz in a multi-cellular case [6]. In this context, SC-FDMA is un-

der consideration for transmission from mobile stations to a Base Station

Subsystem or a Radio Network System.

1.4 IEEE Standards

In addition to the two cellular Partnership Projects, the Institute of Electri-

cal and Electronic Engineers(IEEE) has publishedstandards usedthrough-

out the worldin products with a massmarket. Within the IEEE LAN/MAN

standards committee (Project 802), there are several working groups re-

sponsible for wireless communications technologies. The one with the

greatest inﬂuence to date is IEEE 802.11, responsible for the “WiFi” fam-

ily of wireless local area networks. Two of the networks conforming to the

speciﬁcations IEEE 802.11aand IEEE 802.11gemployOFDM technology

for transmission at bit rates up to 54 Mb/s [7,8]. The other working group

standardizing OFDM technology is IEEE 802.16, responsible for wireless

metropolitan area networks. Among the standards produced by this work-

inggroup,IEEE802.16e,referredtoas“WiMAX”anddescribedinthenext

section, most closely resembles technology under consideration by 3GPP

for cellular long term evolution.

1.5 Advanced Mobile Wireless Systems Based on FDMA

Three standards organizations, IEEE, 3GPP, and 3GPP2, have work in

progress on advanced mobile broadband systems using frequency division

transmission technology. The following subsections describe key proper-

ties of Mobile WiMAX (developed by the IEEE), Ultra Mobile Broad-

band (developed by 3GPP2), and 3GPP Long Term Evolution (LTE).

SC-FDMA, the subject of this book, is a component of LTE.

ily of wireless local area network (WLAN) standards, the IEEE 802.16

Working Group on Broadband Wireless Access (BWA) began its work of
