Abstract: Codewords were constructed subject to the constraint that the elements of the codewords use symbols from a fixed, small constellation. The subspaces constructed remain nonintersecting when lifted to the complex field. The construction shows that the codewords are nonintersecting over the finite field. The construction gives full diversity order when the elements of the codewords are restricted to come from a finite field.
