Exact-Repair MDS Code Construction Using Interference Alignment

Abstract—The high repair cost of (n;k) Maximum Distance Separable (MDS) erasure codes has recently motivated a new class of MDS codes, called Repair MDS codes, that can significantly reduce repair bandwidth over conventional MDS codes. In this paper, we describe (n;k;d) Exact-Repair MDS codes, which allow for any failed node to be repaired exactly with access to d survivor nodes,
