Transforms and GroupsThe fundamental properties of Fourier transforms derive from properties of locally compact abelian groups. Fourier transforms are group character transforms, and time-frequency duality is Pontryagin duality. Applications to block codes, MacWilliams identities and fast Fourier transforms are given.

Christopher G. Harris,Padmini Srinivasanin the exact weight distribution of this scheme for some typical interleaves and very short block lengths and compare these results to conventional rate 1/2 turbo codes. The hybrid scheme clearly has a superior weight distribution. We also consider another very interesting turbo-like coding scheme,
