We first present an equivalent definition of relative generalized Hamming weights of a linear code and its subcodes, and develop a method using finite projective geometry. Making use of the equivalent definition and the projective-geometry method, all of the relative generalized Hamming weights of a 3-dimensional q-ary linear code and its subcodes will be determined.Full Tex
