Abstract:

The compressive/compressed sensing (CS) theory, which was proposed in around 2006, is a framework for estimating sparse signals based on incomplete set of noiseless or noisy measurements. In CS, there are two fundamental problems: compression and reconstruction. In this talk, after reviewing the basic concepts of CS, we focus on the compression part, in particular structured sensing matrices as compression operators. Due to the special structures, these compression operators are easier to generate, require less storage space and have theoretical recovery guarantees. Finally, some applications of CS in different areas are introduced and analyzed. This talk is suitable for senior bachelor, graduate and PhD students and researchers who are interested in signal processing and compressed sensing.
