About the Event

Subspace codes and rank-metric codes are two closely related families of codes with a wide range of applications from storage systems to networks. In the first part of this talk, list decoding algorithms for algebraic subspace codes and rank-metric codes are discussed. These algorithms are based on multivariate interpolation in the ring of linearized polynomials and lead to significant improvements in error correction capability of these codes. In the second part, methods for constructing and decoding sparse rank-metric codes are presented. Such codes will allow efficient implementation and low complexity decoding algorithms.

Biography

Hessam Mahdavifar is an Assistant Professor in the Department of Electrical Engineering and Computer Science at the University of Michigan.
