Digital
Communications and Networking 441 (620.441)
Outcomes: Students come to understand the digital communications process;
error control coding principles; the requirements placed on an information
network by different media; the principles and requirements that govern
real-time and computer data communications; and principles of synchronous,
asynchronous and heterogeneous packet-switched transfer modes.
Content: Digital communications: this section of the unit includes a
review of modulation techniques such as QAM, MSK, OFDM, spread spectrum and
builds on the coding theory ‘convolutional codes’; decoding algorithms, special
codes—interleaving, concatenated; applications to channel coding.
Introduction
to networking: topics include historical review of telecommunications; the
open systems interconnect model; sub-network requirements for real-time
communications; the synchronous digital hierarchy; asynchronous transfer mode;
creation of asynchronous transfer capabilities; evolution of integrated networking
and the Internet; the physical layer—framing and synchronisation; principles of
addressing and routing in communication networks; resource management; access
methods; statistical multiplexing; traffic management; source throttling
methods; shapers and policers; discard policies; error control. The topics are
illustrated with examples from current networks.
Assessment: This comprises one written examination, tutorials, tests,
assignments and laboratory reports. Tutorials, tests and assignments allow for
the monitoring of students’ understanding of fundamental concepts as well as
each student’s progress. Reports help develop students’ skills for articulating
ideas clearly, concisely and logically. The written examination provides
students with an opportunity to demonstrate their understanding of digital
communication systems and the principles and requirements of real-time and
computer data communications.
