Digital Communication Systems Using MATLAB® and Simulink®

Here you will find additional materials for using the digital communication simulation with MATLAB and Simulink in undergraduate, graduate and continuing professional education.  These materials complement the text Digital Communication Systems using MATLAB® and Simulink®, 199 pages, ISBN 978-1-58909-621-9, 2009, Bookstand Publishing.

The text is a direct outgrowth of experience in teaching analog and digital communication systems at the undergraduate, graduate and professional level.  The sea change in this material for the student and professional is the introduction of channel noise and non-linearities in the analysis of communication systems within the last decade.  Prior to this time, analog and digital communication systems were presented by analytical equations without noise, and with a hardware laboratory without significant non-linearities.

These tenants for using simulation to teach students digital communication in lecture and laboratory were presented at the 2003 and 2006 Annual Conference of the American Society for Engineering Education.  The tenants were presented utilizing the simulation environment of SystemVue by Agilent Technologies.
