TSR (Tratamiento de la Señal y Radiocomunicaciones/Signal Processing and Radio Communications) is a research group of the UPV/EHU (Universidad del País Vasco/Euskal Herriko Unibertsitatea), based in the Bilbao School of Engineering.

Although the group was initially formed within the Department of Communications Engineering, it now comprises members from four departments: the Department of Communications Engineering, the Department of Applied Mathematics, the Department of Computer Languages and Systems, and the Department of Electronic Technology.

In 2007, the Basque Government awarded us Group A (Excellent) status, which we have maintained ever since.
