ECE 5655 Communication System Design | ECE | Virginia Tech


Course Information


5655: Physical concepts and practical topics providing tools to calculate carrier-to-noise ratio in communication systems are discussed, including: noise processes, polarization topics, atmospheric propagation, receiver components, antennas, system calculation, and case studies.

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.

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.
