ECE 5656 Communication System Design | ECE | Virginia Tech


Course Information


Advanced topics in digital satellite communications are discussed. These include: multiple access, digital modulation, error correction coding, carrier phase and symbol timing recovery.

Why take this course?

EE 5655 includes many items necessary for signal power and noise power budget calculations, thus permitting determination of carrier-to-noise ratio. EE 5656 introduces techniques necessary for the design of sophisticated satellite communication systems. These courses are a conversion of EE 6601 and 6602 from the quarter system.


Prerequisites: 4634

EE 5655 is a system level course drawing on many topics. A knowledge of electromagnetic fields (EE 5105) is necessary. EE 4634 is an introduction to analog and digital communications. It constitutes the background knowledge needed for advanced material in EE 5656.

Major Measurable Learning Objectives

    The objective of EE 5655 is to fill in the background of students sufficiently that carrier-to-noise ratios can be calculated for a wide variety of communication systems. Emphasis is on modeling of physical processes in actual hardware and channels. Topics such as noise processes, propagation effects, and polarization are treated in depth. Case studies provide illustrations of the concepts. The object of EE 5656 is to provide techniques for analysis of the signal aspects of system design for transmission of information.
