About Us ABET ECE 1473Digital commication systems(3 credits) Description: This course introduces the fundamental concept of modern digital-communication systems. Study questions include: what is the maximum amount of information that can be transferred reliably over a channel, and how to design communication systems and signal-waveforms to convey digital information in a spectrally efficient and robust manner. In addition, the advantages and disadvantages of selecting different combinations of system parameters such as signaling bandwidth, transmission-speed, and system-complexity and the impact on system performance are carefully studied. The students are trained with a wide variety of signal-processing analysis and decision-theoretic performance-evaluation tools available from Fourier analysis, probability and random processes, information theory, and channel and source coding theories. Prerequisites: ECE 1552: Signals and Systems Analysis Texts: Leon W. Couch II, Digital and Analog Communication Systems, Prentice Hall, 1997. Course Objectives: Introduce a set of fundamental theories and concepts used in modern communication systems, learn analysis and design tools and apply them to solve modern digital communication engineering problems, and develop functional understanding of some common communication systems. Topics Covered: Fourier analysis and discrete Fourier transform, entropy and information measure, source coding and quantization, channel coding and parity-check codes, Shannon’s channel capacity theorem, baseband digital-signaling, bandpass communication systems, digital modulation schemes, and link budget calculation. Class/Laboratory Schedule: Class meets twice per week, 75 minutes per session. Professional Component Contributions: Students learn about the function and design of a wide variety of common communication systems. Students must complete a one-semester design project, involving the system-level design and Monte Carlo performance evaluation of a coded-modulation communications system.
