Course Resume
A digital communication system is one that transmits a source (voice, video, data, etc.) from
one point to another, by first converting it into a stream of bits, and then into symbols that can
be transmitted over channels (cable, wireless, storage, etc.). The use of the digital bit-stream as
the interface between the source and the channel is universal regardless of what kind of source
and channel are involved. Digital communication principle, with "bit" as the most important
concept of the information age, and applications in computer science, Internet, wireless, etc., is
one of the most successful stories of applying mathematics in engineering designs.
The course gives an overview of the designs of digital communication systems. We explain
the mathematical foundation of decomposing the systems into separately designed source codes
and channel codes. We introduce the principles and some commonly used algorithms in each
component, to convert continuous time waveforms into bits, and vice versa. We give a
comprehensive introduction to the basics of information theory, a rather thorough treatment of
Fourier transforms and the sampling theorem, and an overview of the use of vector spaces in
signal processing.

modulation techniques; receiver design; channel equalization; information theoretic techniques;
block, convolutional, and trellis coding techniques; multiuser communications and spread
spectrum; multi-carrier techniques and FDM; carrier and symbol synchronization. Applications to
design of digital telephone modems, compact disks, and digital wireless communication systems
are illustrated. The concepts are illustrated by a sequence of MATLAB exercises.
