Abstract: An SSRS code is a subset of a Reed-Solomon(RS) code consisting of the RS codewords whose components all lie in a fixed υ-dimensional vector subspace S of GF(pm),SSRS codes are not linear over the field GF(pm),but they are linear over GF(p).In this paper we calculated dimension of the SSRS(subspace subcodes of Reed-Solomon codes)over the fleld GF(pm)(p>2).

Key words: cyclic codes, RS codes, SSRS codes, dimension
