Algebraic construction of interleavers using permutation monomials

We present an algebraic construction for interleavers of length p^r, where p is any prime. These interleavers are very simple to implement and have performance better than random interleavers and other known algebraic constructions. We construct a permutation of Z_p^r using permutations of the elements of the finite field F_p^r given by monomials over the field.
