On Euclidean Hulls of MDS Codes
share
In this paper, we consider some variation of self-dual (extended) generalized Reed-Solomon (GRS) codes when the length of code is even and consider a special case of almost self-dual (extended) GRS codes when the length is odd. The dimensions of Euclidean hulls of such codes can be determined. It turns out our constructions are more general than previous works on Euclidean hulls of (extended) GRS codes.
