		Multimedia communication technology : representation, transmission and identification of multimedia signals / par Ohm, Jens-Rainer. Publication : [S.l.] : Springer, 2004 . 859 p. ; , Excellent textbook of multimedia signal processing also dealing with the optimization of multimedia communication systems. It covers the theoretical background of one- and multidimensional signal processing, statistical analysis and modeling, coding and information theory as well as estimation and classification theory. Numerous practical examples are given for algorithms and design of multimedia signal compression and transmission systems, for systems performing content analysis and indexing of multimedia signals. Principles behind multimedia coding and indexing standards, e.g. MPEG-1/-2/-4/-7 are explained in detail, including the most recent developments like the new Advanced Video Coding standard and Motion-Compensated Interframe Wavelet Coding. Numerous figures and examples illustrate the concepts. As the book is based on a graduate-level university course, most chapters are supplemented by exercises. The book is also a self-contained introduction both for researchers and developers of multimedia communication systems in industries. 25 cm.

		Orthogonal frequency division multiplexing for wireless communications. Publication : [S.l.] : Springer, 2006 . 308 p. ; , Orthogonal Frequency Division Multiplexing for Wireless Communications is an edited volume with contributions by leading authorities in the subject of OFDM. Its coverage consists of principles, important wireless topics (e.g. Synchronization, channel estimation, etc.) and techniques. Included is information for advancing wireless communication in a multipath environment with an emphasis on implementation of OFDM in base stations. Orthogonal Frequency Division Multiplexing for Wireless Communications provides a comprehensive introduction of the theory and practice of OFDM. Chapter 1, by G. Stþber, briefly introduces the history of OFDM or multicarrier modulation and basic concepts of OFDM, Chapter 2, by Y. (G.) Li, presents design of OFDM systems for wireless communications, various impairments caused by wireless channels, and some other types of OFDM related modulation. Chapter 3 to Chapter 6 address different techniques to mitigate the impairments and to improve the performance of OFDM systems. Chapter 3, by J. Cioffi and L. Hoo, focuses on system optimization techniques, including channel partitioning, loading of parallel channels, and optimization through coding. Chapter 4, by S. Wilson and P. ḍling, addresses timing- and frequency-offset estimation in OFDM systems. It also briefly discusses sampling clock offset estimation and correction. Chapter 5, by Y. (G.) Li, deals with pilot aided and decision-directed channel estimation for OFDM systems. Chapter 6, by C. Tellambura and M. Friese, discusses various techniques to reduce the peak-to-average power ratio of OFDM signals. To facilitate the readers, extensive subject indices and references are given at the end of the book. Even though each chapter is written by different experts, symbols and notations in all chapters of the book are consistent. 24 cm.

		Voice and speech quality perception : assessment and evaluation par Jekosch, Ute. Publication : [S.l.] Springer 2010 . 224 p. , Foundations of Voice and Speech Quality Perception starts out with the fundamental question of: "How do listeners perceive voice and speech quality and how can these processes be modeled?" Any quantitative answers require measurements. This is natural for physical quantities but harder to imagine for perceptual measurands. This book approaches the problem by actually identifying major perceptual dimensions of voice and speech quality perception, defining units wherever possible and offering paradigms to position these dimensions into a structural skeleton of perceptual speech and voice quality. The emphasis is placed on voice and speech quality assessment of systems in artificial scenarios. Many scientific fields are involved. This book bridges the gap between two quite diverse fields, engineering and humanities, and establishes the new research area of Voice and Speech Quality Perception. 23 cm.
