Excerpt from An Easy Method of Modulation: By Means of Universal Formulas Almost every teacher of Harmony can count among his amateur pupils a large (perhaps the greater) number, on whom he feels that his instructions are in great part wasted, at least in the sense that they are not applied to some practical purpose, as, for instance, in musical composition or improvisation, for which such pupils have no talent. It is for this large class of harmony-pupils that I have prepared the present work, as offering to them some tangible fruit to be gathered from their studies. For, if such persons will study harmony, they must be assumed to have some aim or other in so doing; and since they do not compose, the next best application of the study of harmony is undeniably the practice of Digressive Modulation - a purely mechanical thing, within the reach of all. Those, therefore, who desire to study harmony sufficiently to be able to pass correctly from one key to another - an accomplishment rarely met with in music-amateurs, even though advanced piano-pupils, - will find assistance in the present work.

From CHAPTER I. Modulation, in general. 1. To modulate, in the strict sense, is, in general, to pass by means of appropriate harmonies from one key to another. For the sake of terseness we will call the key just left the Old Key, the other one the New Key. By "appropriate harmonies" we mean in general such chords as form, in connection with a short harmonic formula called Cadence (see Chapter IX), a bond of union between the old Key and the new. The harmonies used in this work are exclusively major and minor Triads, as being the easiest chords to manage. 2. We may touch upon the domains of a foreign key without intending to leave the original key, - this would not be to modulate, in the strict sense. If, however, we not only pass over into the domains of a foreign key, but settle down in the key by means of its characteristic harmonies embodied in a Cadence, this plainly indicates the relinquishment of the original key, or, in other words, Digressive Modulation. Our means of modulation is, then, the Cadence, in conjunction with certain preceding Triads connecting it with the old key. 3. In our method we reach the new key in every case by means of one and the same simple Cadence-formula, which varies only according as it is to be used for the Major or the Minor Mode. The manner of proceeding is perfectly simple. The determination of the new key to which we are going, of course, also determines the Cadence as being in that key, and our task is to leave the old key by such of its harmonies as can be - as shortly as possible - properly connected (either immediately or mediately) with the Cadence itself. A homely illustration may serve to make this clear. We may imagine a railway-train, carrying with it an arrangement in the form of a movable switch, which can be laid down and stretched out as may be required, to enable the train to leave the main track and connect with auxiliary roads, each leading to a particular station, more or less remote. The Cadence may be likened to one of these auxiliary roads; for, as soon as we have safely made the connection (from the old key to the initial Triad of the Cadence) by means of the movable switch (the intermediate Triads, few or many), we leave the main track (the old key), and our task is as good as done, - the auxiliary road (the Cadence) will unerringly conduct us to the desired new station (the new key).

By introducing the superspace formalism, the methods of structure analysis of incommensurate structures have achieved in the past few years a full maturity. The superspace description is also becoming in the field of quasicrystals the main tool to approach a systematic method of structure determination of these materials. According to the program of the Workshop, these proceedings are an introduction to the formalism and practice of structure determination of modulated structures (incommensurate and commensurate) and quasiperiodic systems, mainly under the unifying framework of the superspace description. Accordingly, a large set of tutorial introductory chapters written by well-known specialists are included. The main refinement programs available for incommensurate structures are presented by their authors. The book also contains the most recent contributions from more than thirty of the participants in the Workshop, focusing on the problem of the structure analysis of these typical materials by means of diffraction methods.

Explores the fundamentals required to understand, analyze, and implement space modulation techniques (SMTs) in coherent and non-coherent radio frequency environments This book focuses on the concept of space modulation techniques (SMTs), and covers those emerging high data rate wireless communication techniques. The book discusses the advantages and disadvantages of SMTs along with their performance. A general framework for analyzing the performance of SMTs is provided and used to detail their performance over several generalized fading channels. The book also addresses the transmitter design of these techniques with the optimum number of hardware components and the use of these techniques in cooperative and mm-Wave communications. Beginning with an introduction to the subject and a brief history, Space Modulation Techniques goes on to offer chapters covering MIMO systems like spatial multiplexing and space-time coding. It then looks at channel models, such as Rayleigh, Rician, Nakagami-m, and other generalized distributions. A discussion of SMTs includes techniques like space shift keying (SSK), space-time shift keying (STSK), trellis coded spatial modulation (TCSM), spatial modulation (SM), generalized spatial modulation (GSM), quadrature spatial modulation (QSM), and more. The book also presents a non-coherent design for different SMTs, and a framework for SMTs’ performance analysis in different channel conditions and in the presence of channel imperfections, all that along with an information theoretic treatment of SMTs. Lastly, it provides performance comparisons, results, and MATLAB codes and offers readers practical implementation designs for SMTs. The book also: Provides readers with the expertise of the inventors of space modulation techniques (SMTs) Analyzes error performance, capacity performance, and system complexity. Discusses practical implementation of SMTs and studies SMTs with cooperative and mm-Wave communications Explores and compares MIMO schemes Space Modulation Techniques is an ideal book for professional and academic readers that are active in the field of SMT MIMO systems.

The last ten years have seen a great flowering of the theory of digital data modulation. This book is a treatise on digital modulation theory, with an emphasis on these more recent innovations. It has its origins in a collabor ation among the authors that began in 1977. At that time it seemed odd to us that the subjects of error-correcting codes and data modulation were so separated; it seemed also that not enough understanding underlay the mostly ad hoc approaches to data transmission. A great many others were intrigued, too, and the result was a large body of new work that makes up most of this book. Now the older disciplines of detection theory and coding theory have been generalized and applied to the point where it is hard to tell where these end and the theories of signal design and modulation begin. Despite our emphasis on the events of the last ten years, we have included all the traditional topics of digital phase modulation. Signal space concepts are developed, as are simple phase-shift-keyed and pulse-shaped modulations; receiver structures are discussed, from the simple linear receiver to the Viterbi algorithm; the effects of channel filtering and of hardlimiting are described. The volume thus serves well as a pedagogical book for research engineers in industry and second-year graduate students in communications engineering. The production of a manageable book required that many topics be left out.

The high level of technical detail included in standards specifications can make it difficult to find the correlation between the standard specifications and the theoretical results. This book aims to cover both of these elements to give accessible information and support to readers. It explains the current and future trends on communication theory and shows how these developments are implemented in contemporary wireless communication standards. Examining modulation, coding and multiple access techniques, the book is divided into two major sections to cover these functions. The two-stage approach first treats the basics of modulation and coding theory before highlighting how these concepts are defined and implemented in modern wireless communication systems. Part 1 is devoted to the presentation of main L1 procedures and methods including modulation, coding, channel equalization and multiple access techniques. In Part 2, the uses of these procedures and methods in the wide range of wireless communication standards including WLAN, WiMax, WCDMA, HSPA, LTE and cdma2000 are considered. An essential study of the implementation of modulation and coding techniques in modern standards of wireless communication Bridges the gap between the modulation coding theory and the wireless communications standards material Divided into two parts to systematically tackle the topic - the first part develops techniques which are then applied and tailored to real world systems in the second part Covers special aspects of coding theory and how these can be effectively applied to improve the performance of wireless communications systems
