Sparse stochastic processes: A statistical framework for modern signal processing

2013 20th International Conference on Systems, Signals and Image Processing (IWSSIP), 2013
Summary form only given. We introduce an extended family of sparse processes that are specified by a generic (non-Gaussian) innovation model or, equivalently, as solutions of linear stochastic differential equations driven by white Levy noise. We present the mathematical tools for their characterization.

Signal Processing for Sparse Discrete Time Systems

2013
In recent years compressive sampling (CS) has appeared in the signal processing literature as a legitimate contender for processing of sparse signals. Natural signals such as speech, image and video are compressible. In most signal processing systems dealing with these signals the signal is first sampled and later on compressed.

Some methods of digital processing of sparse signals

Radioengineering
When digitizing signals, it is necessary to match the dynamic range of the analog-to-digital converters and the signals being recorded. In practice, there are situations where it is necessary to digitize and transmit signals with different amplitudes, ranging from noise to signals from nearby radio systems, with the same accuracy over communication ...
