Like its earlier editions, this book provides a mathematicallyrigorous overview of physical layer wireless communications. The basic pedagogicmethodology is to include fully detailed derivations from first principles. The text isintended to provide enough principle material to guide the novice student, whilit the same time having plenty of detailed material to satisfy graduate studentsinclined to pursue research in the area. The book is intended to stress the principlesof wireless communications that are applicable to a wide array of wireless standardsIt is intended to serve as a textbook and reference for graduate students, and a usefulreference for practicing engineersOrganization of the bookChapter 1 begins with an overview that is intended to introduce a broad array ofissues relating to wireless communications. Included is a brief description of theevolution of various wireless standards, the basic concepts of cellular frequencyreuse, the land mobile radio propagation environment, link budgets, and coverageand capacity of cellular radio systemsChapter 2 provides an extensive treatment of radio propagation, since goodunderstanding of the physical wireless channel is essential for the developmentand deployment of wireless systems. The chapter begins with a treatment ofthe narrow-band faded envelope for conventional fixed-to-mobile channels foundin cellular radio systems, mobile-to-mobile channels found in mobile ad henetworks, and multiple-input multiple-output (MIMO) channels where multipleantennas are used at both the transmitter and receiver to achieve high capacity afterconsidering the narrow-band channel, we consider the statistical treatment of wide-band channels. The emulation of wireless channels is essential for the developmentand testing of wireless systems, and the chapter provides a detailed discussion ofchannel simulation techniques. Finally, the chapter concludes with a discussion ofshadowing and path loss models for land mobile radio environmentsPreraceChapter 3 provides a detailed treatment of co-channel interference which is therimary impairment in spectrally efficient cellular frequency reuse systems. Veryoften the receivers in such systems are affected by multiple co-channel interferersand the probability distribution of the total interfering power is considered. Thchapter also considers the link outage performance due to co-channel interferencein a variety of wireless environmentsChapter 4 covers the various types of modulation schemes that are used in mobilecommunication systems along with their spectral characteristics. The chapter beginswith the mathematical representation of bandpass modulated signals, along withNyquist pulse shaping. Later, a large variety of modulation schemes used in wirelesssystems are considered, including both single-carrier and multi-carrier modulation,and both linear and nonlinear modulation techniques This is followed by a treatmentof the power density spectrum of modulated signals. Although quite mathematicalin nature, power spectrum is an important topic, since wireless systems are requiredto operate within a specified out-of-band emission maskChapter 5 discusses the error probability performance of various digital modulation schemes on narrow-band fat fading channels. The performance is evaluatedwith a variety of receiver structures, including coherent detectors, differentialcoherent detectors and noncoherent detectorsChapter 6 includes a treatment of multi-antenna techniques for combatingenvelope fading. The chapter includes a discussion of various diversity combiningtechniques for coherent, differentially coherent, and noncoherent receiver detectionof signals on fading channels with additive white gaussian noise. also consideredis optimal combining which is effective when the primary additive impairment isco-channel interference rather than noise. Finally, the chapter considers the use ofmultiple antennas at the transmitter in the context of classical beam-forming andtransmit diversityChapter 7 provides an extensive treatment of digital signaling on intersymbolinterference(ISI) channels that are typical of broadband land mobile radio systemsThe chapter begins with the characterization of Isi channels and goes on todiscuss techniques for combating ISI based on symbol-by-symbol equalization andsequence estimation. Later, error probability for maximum likelihood sequenceestimation is considered. The chapter concludes with a discussion of co-channeldemodulation for the purpose of mitigating co-channel interference on Isi channelsChapter 8 covers error control coding techniques for wireless systems. Thechapter begins with a discussion of basic block coding including space-time blockcodes Convolutional coding is considered next along with the Viterbi and BCJRalgorithms for decoding convolutional codes, followed by trellis coded modulationThe chapter then provides a detailed discussion on the design and performanceanalysis of convolutional and trellis codes for awgn channels, and interleaved fatfading channels, and fading isi channels. Later, space-time trellis codes are treatedand the chapter concludes with Turbo codinChapter 9 is devoted to spread spectrum techniques The chapter begins with anintroduction to direct sequence and frequency hop spread spectrum. This is followedy a detailed treatment of spreading sequences. Also included is a discussionPrefaceof the effects of tone interference on direct sequence spread spectrum, and theRAKE receiver performance on wide-band channels. The chapter wraps up witha discussion of cdma multiuser detectionChapter 10 is devoted to multi-carrier techniques. It considers the performanceof ofdm on frequency-selective channels and considers the effect of residualISI and problem of residual ISI cancellation. Later, the chapter examines singlecarrier frequency-domain equalization(SC-FDE)techniques. This is followed by atreatment of orthogonal frequency division multiple access (OFDMA)on both theforward and reverse links. The chapter concludes with a discussion of single-carrierfrequency division multiple acceSs (SC-FDMA)Chapter 11 considers frequency planning techniques for cellular systems. Thechapter begins with a discussion of cell sectoring, cell splitting, and reuse partition-ing. Later, the chapter considers radio planning for OFDMa cellular systems. Thisis followed by hierarchical overlay/underlay architectures based on cluster planningFinally, the chapter wraps up with macrodiversity TDMA cellular architecturesChapter 12 considers CDMa considers CDMA cellular systems, consideringtopics such as capacity and power control This is followed by a discussion ofhierarchical macrodiversity CDMa architectures and their performanceChapter 13 is devoted to cellular radio resource management. The chapter beginswith an introduction to basic hard and soft handoff. Later, the chapter considers theimportant problem of link quality evaluation, including signal strength averaging,velocity estimation, and velocity adaptive hard handoff algorithms later, a detailedanalysis of hard and soft handoff is provided. Finally, the chapter wraps up withmethods for estimating received carrier-to-interference plus noise ratio(CINR)The Appendix includes a brief and focused tutorial discussion of probabilityand random processes. A good understanding of the material in the Appendix isessential, since the concepts are widely used throughout the textUSing This Book for InstructionThe book has been developed from a graduate-level course on physical wirelesscommunications that I have taught at Georgia Tech since 1993. Normally, I prefera graduate-level course in digital communications as a prerequisite for this courseHowever, such a prerequisite may be waived to the extent that there is extensivebackground material in each chapter. A course may cover the introductory materialin each chapter and skip the more specialized material. In my own classes, I alwaystry to judge the mathematical level of the students early and adapt accordinglyThe book obviously contains far too much material to be taught in a onesemester course. However, i believe that it can serve as a suitable text in mostsituations through the appropriate instructor selection of background sections. Myown preference for a one semester course is to include the following material inorder: Chap. 1, Chap 2(skipping the more advanced material), and the first twosections of Chap 3. In moving to modulation waveforms in Chap. 4, an instructormay have to treat/assume basic signal-space representation. However, most students
