Waveforms for Computing Over the Air: A groundbreaking approach that redefines data aggregation

Over-the-air computation (AirComp) leverages the signal superposition characteristic of wireless multiple-access channels (MACs) to perform mathematical computations. Initially introduced to enhance communication reliability in interference channels and wireless sensor networks (WSNs), AirComp has more recently found applications in task-oriented communications like wireless distributed learning and in wireless control systems.

Raison d’Être: 2025 Edition [President’s Message]

In his January 2012 column for IEEE Signal Processing Magazine, K. J. Ray Liu, then president of the IEEE Signal Processing Society (SPS), highlighted the importance of establishing a formal community when individuals come together to create a professional society [1]. He emphasized that the Society’s primary mission, its raison d’être, is to serve its community, and the key to achieving this mission is to serve its members effectively.

Looking Back on My First Year as Editor-in-Chief and Reflecting on the Challenges Ahead

One year has passed since I began my term as the editor-in-chief (EiC) of IEEE Signal Processing Magazine (SPM). It has been a busy first year, with a rich set of challenges that go beyond those I have experienced in previous volunteer positions. This is welcome: with giving back to our community comes the desire to grow through new challenges and experiences, especially for those of us approaching our wiser years.
