· Introduction to compressive sensing¶. In this section we formally define the problem of compressed sensing. Compressive sensing refers to the idea that for sparse or compressible signals a small number of nonadaptive measurements carries sufficient information to approximate the signal well. In the literature it is also known as compressed sensing and compressive sampling.

Compressed Sensing (CS) is a novel sensing/sampling paradigm that allows the recovery of sparse (few nonzeros) or compressible (quickly decaying entries) signals from far fewer measurments than the Nyquist rate. The sparsity assumption is easily realized in practice as for instance natural images are sparse in the Wavelet domain (e.g

· Compressed Sensing. An alternative theory to Nyquist s Law that indicates signals and images can be reconstructed from fewer measurements than what is usually considered necessary. In contrast Nyquist s Law states that a signal must be sampled at least twice its highest analog frequency in order to extract all of the information.

· In compressive sensing the aim is to obtain the relavent information in as few measurements as possible. In multiplexing the goal is to overcome limitations mainly due to lack of SNR. Many compressive sensing schemes also employ multiplexing. One useful example of compressive sensing versus traditional sensing is the single pixel camera.
