A closed form formula of the partition weight enumerator of maximum distance
separable (MDS) codes is derived for an arbitrary number of partitions. Using
this result, some properties of MDS codes are discussed. The results are
extended for the average binary image of MDS codes in finite fields of
characteristic two. As an application, we study the multiuser error probability
of Reed Solomon codes.Comment: This is a five page conference version of the paper which was
