Preface

Prof. Dr. Khamies Mohammed Ali El-Shennawy, the author, believes that the book: “Communication Theory and Signal Processing for Transform Coding”, is tailored for the requirements of the individual area of the signal processing in communication systems. The students of the undergraduate studies in the institutes, colleges, universities, and academies and want to specialize in the field of communication systems and signal processing, this book, is their innovation, and is more essential to them before the entrance of their specialized work in communication systems, in order to get the talent and the ability to have the faster solution for all the problems in analog and digital communication and their applications. Prof. El-Shennawy teach to the students of the undergraduate studies: circuit theory, communication theory, communication systems, data communication, electro-magnetic, antennas, and acoustics, and supervise the graduation projects as applications of Surface Acoustic Wave SAW devices in communication systems, communication security systems (encryption and decryption techniques, stream cipher, Data Encryption Standard DES, public key encryption, factorization and logarithmic and elliptic curve encryption and signature techniques, advanced encryption standard), global maritime distress and safety systems, electronic chart display and information systems, global positioning systems, air-borne and space-borne remote sensing. Also supervise and teach to the students of the graduate and post graduate studies for diploma of high studies, M.Sc. and Ph.D. courses: communication intelligence, data computer communication, surface acoustic wave devices and charge coupled devices in modern communication systems, ultra wide band technique, speech and digital coding, voice over internet protocol, audio and video compression (transform coding), source coding techniques, speech and digital watermarking, in the Arab Academy for Science and Technology and Maritime Transport AASTMT, College of Engineering and Technology, Department of Communication & Electronics and Computer Studies, Alexandria, Egypt, since 1988 to 2014 and still, three semesters every year.

This book contains a great number of numerous examples and solved problems and exercises, to explain the methodology of Fourier analysis, Fourier series, Fourier transform and properties, Discrete Fourier Transform DFT, Fast Fourier Transform FFT, Discrete Cosine Transform DCT, Discrete Wavelet Transform DWT, Contourlet Transform CT. The book proves that the students need mathematics in communication more than you may think, and make the student has the ability to deal with the DFT, FFT, DCT, DWT, and CT, utility computer programs. The advantage of this book is the simplicity, attract the student, easy to solve the problems using different ways, and with its wider contents in communication theory, applied in communication systems.

Also, this book is beneficial to the engineers of the graduate and post graduate studies, and to the researchers in the research centers because the book contains a great number of mathematical operations and is considered very important in the research results, solving their problems. The book is a big jump to the students and engineers in understanding, realization, and makes the understanding of their prediction fields wider. The book is a very good chance to the students and the engineers for verifying their predictive results in the communication problems and give them more trust. The book is considered, the first step, mathematically solving the communication problems.

Chapter I is an introduction to the model of communication system, signal contamination, why modulation and demodulation, Shannon-Hartley theorem, some basics concepts of signals and classification of signals waveforms: periodic and unperiodic, deterministic and random, Dirac delta function, unit step function, power and energy, causal and non-causal, analog and digital, and low-pass and band-pass signals, and five solved problems, as well as numerical examples.

Chapter II is review of the classical methods for the spectral analysis of the Fourier series and power spectra, Fourier series real coefficients and complex exponential coefficient methods, orthogonality, spectrum of periodic signals (discrete spectrum), sinc function, Parseval`s power theorem, power spectral density, and eleven solved problems, as well as numerical examples.

Chapter VIII describes the Hilbert transform, Hilbert transform of sinusoidal functions, Hilbert transform and orthogonality, Hilbert transform and convolution principle, Hilbert transform of narrow band-pass signals, some important Hilbert transforms, and four solved problems, as well as numerical examples.

Chapter IX explains different analysis of the narrow band-pass signals and systems, pre-envelope, complex envelope, natural envelope, band-pass systems, equivalent lowpass technique, new design criterion for band-pass systems (Kham-Shen Criteria), input/output pre-envelope technique, dispersive systems, and envelope delay (group delay), and seven solved problems, as well as numerical examples.

Chapter X illustrates the numerical computation of the Fourier transform, sampling theorem, discrete Fourier transform and properties (linearity, shifting, and circular convolution), fast Fourier transform, sine and cosine transforms, discrete cosine transform, drawbacks of Fourier transform, short time Fourier transform, wavelet transform, discrete wavelet transform, contourlet transform, some application of compression techniques, lossless and lossy coding, Huffman encoding, run length encoding, Lempel-Ziv-Wekh encoding, predictive encoding, delta encoding, drawbacks of compression techniques, audio compression, MPEG layers I, II, III of audio compression, video compression, Joint Photographic Experts Group JPEG, JPEG initiative (JPEG 2000), Moving Picture Experts Group MPEG, MPEG-2, MPEG-4, principles behind compression, MPEG-4 International Standard (MP4), Transformdomain weighted interleave Vector Quantization TwinVQ in MPEG-4, comparison of MPEG-4 (H.264) and JPEG-2000 video compression, and fourteen solved problems, as well as numerical examples.

The ten chapters of the book are essentially suited for two semesters. The first semester on communication theory (from chapter one to chapter nine). It is expected that the reader has knowledge of mathematics, electronics, and circuit theory. The second semester on signal processing, audio and image processing, numerical computation, transform coding and compression techniques (chapter ten). The book is characterized by three directions, the mathematical point of view, the communication theory point of view, and the utility computer programs. The make up of the material for each course may be determined only by the backgrounds and interests, thereby allowing considerable flexibility in making up the course material. As an aid to the teacher of each course, a detailed solutions manual for all the unsolved problems which at the end of the chapters, is available from the publisher.
