The Signal Processing for Communications and Navigation (SPCOMNAV) research group at Universitat Autonoma de Barcelona (UAB) seeks researchers to contribute to the activities on 5G and GNSS positioning in urban and vehicular environments (V2X), currently ongoing at the group. The researchers will benefit from the strong and intense links of SPCOMNAV with industry and European institutions, being involved in international research projects contributing to make a leap forward in the current state of the art.
