Available in PDF, EPUB and Kindle. Book excerpt: Coded Modulation Systems is an introduction to the subject of coded modulation in digital communication. It is designed for classroom use and for anyone wanting to learn the ideas behind this modern kind of coding. Coded modulation is signal encoding that takes into account the nature of the channel over which it is used. Traditional error correcting codes work with bits and add redundant bits in order to correct transmission errors. In coded modulation, continuous time signals and their phases and amplitudes play the major role. The coding can be seen as a patterning of these quantities. The object is still to correct errors, but more fundamentally, it is to conserve signal energy and bandwidth at a given error performance. The book divides coded modulation into three major parts. Trellis coded modulation (TCM) schemes encode the points of QAM constellations; lattice coding and set-partition techniques play major roles here. Continuous-phase modulation (CPM) codes encode the signal phase, and create constant envelope RF signals. The partial-response signaling (PRS) field includes intersymbol interference problems, signals generated by real convolution, and signals created by lowpass filtering. In addition to these topics, the book covers coding techniques of several kinds for fading channels, spread spectrum and repeat-request systems. The history of the subject is fully traced back to the formative work of Shannon in 1949. Full explanation of the basics and complete homework problems make the book ideal for self-study or classroom use.

Available in PDF, EPUB and Kindle. Book excerpt: Space-tune coding is a promising transmit diversity technique for future wireless systems equipped with multiple antennas. Two practical space-time coding design issues are the coding performance and the decoding complexity. In this thesis, space-time trellis code design with simple decoding is discussed. The essential idea is to concatenate an outer multiple trellis coded modulation (MTCM) encoder with an inner orthogonal (or orthogonal-like) space-time block code (OSTBC). The outer MTCM is designed to achieve a high coding gain while the inner block code is used to devise a simple decoding. First, space-tune coded CPM system design is studied. Due to the inner memory of CPM modulators, this design problem can be seen as a special case of space-tune trellis code design. An orthogonal space-time coded partial response continuous phase modulation (CPM) system (OST-PCPM) with two transmit antennas is proposed. Based on the orthogonality of transmit signals and the proposed differential encoding scheme, a fast decoding algorithm is developed for some special cases. A suboptimal decoding method is developed to provide a tradeoff between complexity and performance. Then, a differential space-time trellis-coded scheme is presented. Based on the per-survival processing technique (PSP), a low-complexity suboptimal differential decoder is developed. In slow fading channels, it can approach the performance of SOSTTC with coherent decoding. Furthermore, in time-varying channels, a bank of recursive least square (RLS) type channel predictors are incorporated into the Viterbi decoder to track the channel variance. In order to achieve power efficiency, a super-orthogonal space-time trellis coding (SOSTTC) scheme with quadrature amplitude modulation (QAM) constellations is devised. A systematic set-partitioning method for QAM constellations is given. Furthermore, trellis shaping based on set partitioning is incorporated in SOSTTC with QAM symbols to achieve extra shaping gain. Peak constraints can be used to limit the constellation expansion ratio and peak-to-average power ratio (PAPR). At last, the optimal rotations for quasi-orthogonal space-tune block codes (QOSTBC) with M-ary phase shift key (MPSK) modulation are given. A new family of space-tune trellis codes for four and more than four transmit antenna systems are devised, which are based on our new designed QOSTBC with minimum decoding complexity (QOSTBC-MDC). The proposed set-partitioning method can be used for systems with more than four transmit antennas directly. Furthermore, its decoding complexity is low, thanks to the new designed inner block codes. Several design examples are presented.

This book was released on 2012-12-06 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 39 (thesis year 1994) a total of 13,953 thesis titles from 21 Canadian and 159 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 39 reports theses submitted in 1994, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.
