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 Electrical Engineering.

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