'''Prerequisites:''' ''EE 483, Introduction to Digital Signal Processing'' and ''EE 441, Applied Linear Algebra for Engineering'', or equivalent courses. Please note that the course will assume some knowledge of standard DSP concepts as well as of some basic linear algebra. If you took these two courses some time ago it would be a good idea to review some of the key material early in the semester.

USC seeks to maintain an optimal learning environment. General
−
     
+
principles of academic honesty include the concept of respect for the
−
  </ul>
+
intellectual property of others, the expectation that individual work
 +
will be submitted unless otherwise allowed by an instructor, and the
 +
obligations both to protect oneís own academic work from misuse by
 +
others as well as to avoid using anotherís work as oneís own. All
 +
students are expected to understand and abide by these
 +
principles. Scampus, the Student Guidebook, contains the Student
 +
Conduct Code in Section 11.00, while the recommended sanctions are

located in Appendix A [http://www.usc.edu/dept/publications/SCAMPUS/gov/ http://www.usc.edu/dept/publications/SCAMPUS/gov/ ]

EE 596, Wavelets, Spring 2016

Course Description: The theory and application of wavelet decomposition of signals. Includes subband coding, image compression, multiresolution signal processing, filter banks, and time-frequency tilings.

Prerequisites: EE 483, Introduction to Digital Signal Processing and EE 441, Applied Linear Algebra for Engineering, or equivalent courses. Please note that the course will assume some knowledge of standard DSP concepts as well as of some basic linear algebra. If you took these two courses some time ago it would be a good idea to review some of the key material early in the semester.

Material Covered (Subject to Change)

  • Weeks 1 and 2 Introduction and Motivation. Signal representation using bases. Hilbert spaces. Orthogonal, bi-orthogonal basis and overcomplete expansions. Example: representing finite energy continuous signals using Haar basis. Example of construction of Haar basis
  • Week 3 Bases for discrete signals. Finite and infinite dimensional spaces.
  • Week 4 Overcomplete expansions. Searching for the best representation. Matching pursuits and variations. Compressed sensing.
  • Weeks 5 and 6 Multirate signal processing. Filterbanks and discrete wavelet transforms. Time domain, frequency domain and polyphase domain representations.
  • Week 7 and 8 2-Channel orthogonal filterbanks. Iterated filterbanks. Bi-orthogonal filterbanks. Lifting factorizations. Multichannel filterbanks. Modulated filterbanks.

Projects

  • Project requirements:
    • Projects should be done individually.
    • Each project must involve using the wavelet transform as a tool. A signal is analyzed/classified, etc by computing its wavelet transform and then the required task (e.g. denoising/classification) is performed in the transform domain.
    • The Matlab toolbox or C libraries can be used for the project. C libraries are available at Dartmouth and Rutgers.
    • Whichever method is used, the source code will have to be made available along with the project report (only for the routines that you write, which could call those available in matlab or C.)
  • Reporting requirements: a final report and a class presentation.
  • Project descriptions and references
  • Test data for the projects
  • Software packages

Statement for Students with Disabilities

Any student requesting academic accommodations based on a disability is required to register with Disability Services and Programs (DSP) each semester. A letter of verification for approved accommodations can be obtained from DSP. Please be sure the letter is delivered to me (or to TA) as early in the semester as possible. DSP is located in STU 301 and is open 8:30 a.m.--5:00 p.m., Monday through Friday. The phone number for DSP is (213) 740-0776.


Statement on Academic Integrity

USC seeks to maintain an optimal learning environment. General principles of academic honesty include the concept of respect for the intellectual property of others, the expectation that individual work will be submitted unless otherwise allowed by an instructor, and the obligations both to protect oneís own academic work from misuse by others as well as to avoid using anotherís work as oneís own. All students are expected to understand and abide by these principles. Scampus, the Student Guidebook, contains the Student Conduct Code in Section 11.00, while the recommended sanctions are located in Appendix A http://www.usc.edu/dept/publications/SCAMPUS/gov/

Students will be referred to the Office of Student Judicial Affairs and Community Standards for further review, should there be any suspicion of academic dishonesty. The Review process can be found at http://www.usc.edu/student-affairs/SJACS/.
