Sensing reality and communicating bits: a dangerous liaison
Michael Gastpar, Martin Vetterli, Pier Luigi Dragotti · IEEE Signal Processing Magazine · 2006
To illustrate the conceptual issues related to sampling, source representation/coding and communication in sensor networks, we review the underlying theory and discuss specific examples. We show how the structure of the distributed sensing and communication problem dictates new processing architectures. The key challenge lies in the discretization of space, time and amplitude, since most of the advanced signal processing systems operate in discrete domain.
