Principles Of Signals & Systems (ENT 217/3)

Multimedia signals include different data types (text, sound, graphics, picture, animations, video, etc.), which can be time-dependent (sound, video and animation) or spatially-dependent (images, text and graphics). Hence, the multimedia systems represent an interdisciplinary cross-section of the following areas: digital signal processing, computer architecture, computer networks and telecommunications. Multimedia Signals and Systems is an introductory text, designed for students or professionals and researchers in other fields, with a need to learn the basics of signals and systems. A considerable emphasis is placed on the analysis and processing of multimedia signals (audio, images, video). Additionally, the book connects these principles to other important elements of multimedia systems such as the analysis of optical media, computer networks, QoS, and digital watermarking.

This text introduces the reader to the theory of multi-port signals and systems, with a focus on vector-valued signal transmission. Of primary interest is the dynamic behavior of electrical multiple-input multiple-output (MIMO) systems. The book provides a basic understanding of the fundamentals, implementation, and applications of MIMO techniques. These techniques, in conjunction with several "classic" signal processing algorithms, are illustrated by means of numerous worked examples and software on the accompanying CD-ROM. MATLAB(r). This matrix-oriented commercial software package with user-friendly interfaces and excellent graphics support was chosen to perform the numerical analyses. End-of-chapter problems are added to provide additional training opportunities and to reinforce the knowledge gained.Over the last decade, spurred by the invention of a series of fundamentally new wireless transmission concepts, MIMO theory has been transformed into one of the most vibrant and active research areas. A person with no previous training or experience in the various fields of electromagnetics, radio technology, wireless transmission systems, coding and digital modulation theory, etc., is in danger of getting lost right at the start of a MIMO project. It is the purpose of this text to take away at least some of the load from students, researchers, and interested practitioners. It can be used in telecommunications transmission and switching, systems and information theory, and signal processing courses.
