Perspectives on special issues [From the Editor]

The special issues of IEEE Signal Processing Magazine (SPM) provide a forum wherein a collection of tutorials, concentrated on a specific topic, span the entire field and expose a wide-ranging segment of readers in the signal processing community to a thorough overview of the topic. The presentation of complementary tutorials, focused on a particular area in signal processing and aimed at a broad technical audience, is a unique feature of this publication. The wide exposure of selected topics to a large audience makes the special issues in SPM a top venue to educate and raise the prominence of important disciplines in signal processing.
