Welcome Message

Thank you for visiting my page. Below you fill find Simulink exercises that accompany my text Digital Communications: A Discrete-Time Approach published by Pearson Prentice-Hall in 2009. Some helpful features of the exercises include the following:

• The exercises follow the order of topics in the text, for the most part.


• The first few exercises are simple and are primarily designed to help those new to the topic to become familiar with a way to design communication systems in Simulink. Later exercises build on earlier exercises. You will find the later ones more difficult than the earlier ones. This is because the later exercises remove simplifying assumptions and guide the student closer to a real-world scenario.


• Each exercise lists the relevant sections of the textbook. This is done to help students identify the appropriate resource material found in the textbook.

The designs are based on basic blocks from the Simulink, DSP System, and Communication Systems Toolboxes.

Along the top of this page, you find links the Simulink data files and some information about the textbook. I hope you find these exercises useful...
