2020 DLR-MIT-TUM Workshop on Coding and Random Access (CORA)

On February 24-25, 2020, the German Aerospace Center (DLR), the Massachusetts Institute of Technology (MIT) and the Technical University of Munich (TUM) are organizing the 2020 DLR-MIT-TUM Workshop on Coding and Random Accesss (CORA). The workshop will provide an informal atmosphere to discuss recent advances and open challenges in the design of coding schemes for (massive) uncoordinated multiple access systems (IoT/M2M). For more information, please see the workshop web site.

The workshop will be held at the Courtyard by Marriott Hotel in Oberpfaffenhofen, near the DLR campus in Oberpfaffenhofen south of Munich.

Workshop Chairs:
Gianluigi Liva (DLR), Yury Polyanskiy (MIT), Gerhard Kramer (TUM)

Topics of interest

  • Wireless access protocols for IoT, M2M, and URLLC communications
