Permutation Polynomials of Higher Degrees for Turbo Code Interleavers
Jonghoon Ryu · IEICE Transactions on Communications · 2012
Permutation polynomial based interleavers over integer rings, in particular quadratic permutation polynomials have been widely studied. In this letter, higher degree permutation polynomials for interleavers are considered for interleavers and permutation polynomials superior to quadratic permutation polynomials are found for some lengths.
