Digital communication has found an increasing interest in the past 70 years starting
with the telephone network on copper wires, the development of the optical transmission, and the emerging Internet based on wire-line and wireless transmission technologies. Today, the trend to serve an increasing number of mobile users and also machines with information through digital networks is unbroken.
The new book Introduction to Digital Communications is aiming at graduate
students, scientists, and engineers, who are interested in getting an introduction to
modern digital communications. The main focus is on the fundamentals of the
physical layer from the perspective of the theory of linear time-invariant as well as
time-variant systems. The book draws a bow from single input single output to
multiple input multiple output systems with an emphasis on wireless transmission
over time-variant channels. The main concern lies in an accurate mathematical
description, wherein the findings and lemmas are proven in detail. Various chapters
are enriched by numerical examples and also illustrated with results from computer
simulations provided by the open platform “webdemo” of the Institute of
Telecommunications at the University of Stuttgart, http://www.inue.uni-stuttgart.de.
