ECET 47400 - Digital Communications

Credit Hours: 4.0.

This is an advanced course in digital communications concepts and applications. Topics include analog message digitization, signal space representation of digital signals, binary and M-ary signaling methods, the detection of binary and M-ary signals, modulation of digital signals, signaling techniques, digital multiplexing and protocols. Applications of transport technologies using underlying communication protocols are discussed. Transfer of digital information through diverse communication media is emphasized. There is an introductory treatment of probability theory, including distribution and random variables; with the applications of normal and exponential distributions to traffic analysis. Practical application of the technologies and protocols are investigated in the laboratory.

Course Objectives:            

After completing this course, the student should be able to:

1. Describe the roles and functions of major components of voice and data communication systems.

2. Understand the nature of analog signals, their synthesis using Fourier series, the Nyquist criterion and analog to digital conversion.

3. Calculate analog and digital values for A/D and D/A conversion processes.

4. Calculate the information loss in the A/D & D/A conversion process.

5. Demonstrate an understanding of line coding and zero-suppression techniques.

6. Apply probabilistic methods to determine single and multiple bit error probabilities on a link.

7. Perform error rate analysis on multi-level baseband systems.

8. Demonstrate an understanding of medium characteristics, modulation and multiplexing techniques and physical layer framing structures used in the PSTN, wireless and data networks.

9. Apply probabilistic methods to determine trunk capacity required for representative PSTN traffic scenarios.
