Abstract

We consider the code corresponding to a projective system whose support is the union of two linear subspaces with nonempty intersection, and prove that the code is uniquely determined up to equivalence by its weight enumerator. Also we obtain the same conclusion for the complement of the union of two linear subspaces.
