Course description:

Random processes, signals and noise; digital communication over additive white Gaussian noise (AWGN) channels, optimal receiver design, modulation techniques and error performance calculations; communication over bandlimited AWGN channels; power spectra of digitally modulated signals; intersymbol interference; wireless communication systems; data security.

Course Outline:

Introduction and course overview; review of probability theory and random processes (2 weeks)

Digital communication over the additive white Gaussian noise (AWGN) channel (3 weeks)

  • Digital modulation schemes
  • How can we design an optimum receiver which minimizes the probability of error?
  • What is the error performance for various modulation schemes?

Communication over bandlimited AWGN channels (3 weeks)

  • Power spectra of digitally modulated signals
  • Intersymbol interference and mitigating techniques
  • Orthogonal frequency division multiplexing

Introduction to wireless communication systems: fading channel models; diversity; cellular concept (2 weeks)

Data security: system vulnerabilities; random cipher model; encryption methods; physical layer security (1.5 weeks)

Students registered in EECE 571X will be required to do a term paper/project in addition to fulfilling the course requirements for ELEC 431.
