IEEE Signal Processing Society: Celebrating 75 Years of Remarkable Achievements [from the Guest Editors]

It is our great pleasure to introduce the first part of this special issue to you! The IEEE Signal Processing Society (SPS) has completed 75 years of remarkable service to the signal processing community. When the Society was founded in 1948, we couldn’t imagine, for instance, how wireless networks of smartphones would be able to connect us easily at all times, or that an image processing algorithm would be able to detect cancer in a few seconds. Those are just simple examples of the immense technological progress over the past 75 years, which became possible thanks in great part to the dedicated work of professional members of the SPS.
