We develop a kernel-based sampling approach, which allows for perfect reconstruction with a sample complexity equal to the rate of innovation of the signal.

We consider the analysis-sparse l1-minimization problem with a generalized l2-norm-based data-fidelity and show that it effectively corresponds to using a tight-frame sensing matrix.

Time-encoding of continuous-time signals is an alternative sampling paradigm to conventional methods such as Shannon's sampling.
