Introduction to Digital Communications

This book provides an extensive introduction to the theoretical fundamentals of digital communications, covering single-input single-output (SISO), multiple-input multiple-output (MIMO), and time-variant systems. It is divided into three parts, the first of which addresses the principles of wire-line and wireless digital transmission over SISO links. Part II covers the theory of linear time-variant systems, while Part III deals with MIMO systems. It describes MIMO channel models with and without spatial correlation, linear and nonlinear MIMO receivers, and multi-user MIMO schemes. Several new examples and graphs have been added.

This comprehensive textbook provides a thorough introduction to the theoretical foundations of digital communications, encompassing single-input single-output (SISO), multiple-input multiple-output (MIMO), and time-variant systems. Furthermore, the core content is enriched with a plethora of illustrative examples and computer simulations, enhancing its accessibility and practicality. The book is structured into three distinct parts, the first of which delves into the principles of wire-line and wireless digital transmission over SISO links. Digital modulation, intersymbol interference, and diverse detection techniques are explored, along with the introduction of models for realistic time-variant, wireless channels. The equivalent time-variant baseband system model is derived, providing a solid foundation for further discussions.

In addition to its core content, this book introduces two novel topics: blockwise signal transmission and multicarrier modulation with orthogonal frequency-division multiplexing (OFDM) systems. Recognizing that not all readers may have prior familiarity with these subjects, Part II is dedicated to the theory of linear time-variant systems. The generalized convolution is derived, and readers are introduced to impulse response, the delay spread function, and system functions in the frequency domain. Randomly changing systems are also discussed, offering a comprehensive overview of the topic. To enhance the reader's understanding, numerous new examples and graphs have been incorporated into this edition.

Turning our attention to Part III, the book delves into the realm of MIMO systems. It begins by describing MIMO channel models with and without spatial correlation, including the Kronecker model. Linear and nonlinear MIMO receivers are investigated, with a focus on maximizing channel capacity and determining the optimal number of bits per channel that can be transmitted. Principles of space–time coding are outlined to enhance transmission quality and increase data rates. In conclusion, the book explores multi-user MIMO schemes, which aim to reduce interferences and improve overall communication performance.

By offering a comprehensive and in-depth exploration of digital communications, this textbook serves as an invaluable resource for students, scientists, and engineers seeking to gain a deeper understanding of this field. Its well-organized structure, accompanied by ample illustrations and simulations, ensures a smooth learning experience and fosters a strong grasp of the theoretical principles and practical applications of digital communications.
