This book offers students, scientists, and engineers 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.
Further, the main content is supplemented by a wealth of
representative examples and computer simulations. The book is
divided into three parts, the first of which addresses the
principles of wire-line and wireless digital transmission over SISO
links. Digital modulation, intersymbol interference, and various
detection methods are discussed; models for realistic time-variant,
wireless channels are introduced; and the equivalent time-variant
baseband system model is derived. This book covers two new topics
such as blockwise signal transmission and multicarrier modulation
with orthogonal frequency-division multiplexing (OFDM) systems.
Since not all readers may be familiar with this topic, Part II is
devoted 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. In addition, randomly changing systems are
discussed. Several new examples and graphs have been added to this
book. In turn, Part III deals with MIMO systems. It describes MIMO
channel models with and without spatial correlation, including the
Kronecker model. Both linear and nonlinear MIMO receivers are
investigated. The question of how many bits per channel use can be
transmitted is answered, and maximizing channel capacity is
addressed. Principles of space-time coding are outlined in order to
improve transmission quality and increase data rates. In closing,
the book describes multi-user MIMO schemes, which reduce
interference when multiple users in the same area transmit their
signals in the same time slots and frequency bands.
