“Compressive Sampling for Biomedical Applications: An Introduction”

A central objective of EEDSP is the efficient representation of biomedical signals. The traditional approach to acquiring and representing a signal efficiently is through Nyquist sampling followed by either direct or transform-based compression. This methodology is often wasteful as much of the data acquired via sampling is discarded at the compression stage. Compressive Sampling is an emerging field in DSP where such wasteful sampling is eliminated by simultaneously acquiring and expressing the signal in a sparse basis. This talk provides an introduction to compressive sampling and relates the concepts involved to traditional compression methods.
