Coding for Communications and Data Storage (COD)

In the COD group, Hans Fischer Fellow Prof. Camilla Hollanti (Aalto University) and her host Rudolf Mößbauer Tenure Track Prof. Antonia Wachter-Zeh (TUM Department of Electrical and Computer Engineering) focus on error-correcting codes and their application in communication systems and data storage. One basic research area of the group is algebraic coding theory (Reed-Solomon, BCH, rank-metric codes) and efficient decoding algorithms. Applying coding theory for data storage in non-volatile memories, such as flash memories and phase change memories, and for distributed data storage systems is in the core of the COD group's research. The area of coding for storage also includes coding for DNA storage based on correcting insertions and deletions. Further, secure transmission schemes and secure storage of data and how these can be achieved using code-based cryptosystems is in the research focus of the COD group.
