Quadratic Permutation Polynomial Interleavers for 3gpp Lte Turbo Codes
The contention-free property of interleavers is one of the key design requirements for the parallel decoding implementations of turbo codes in order to achieve high decoding throughput. Quadratic permutation polynomial (QPP) interleavers are maximum contention-free (MCF), i.e., every factor dividing the interleaver length becomes a possible degree of parallel decoding processing without any mem...
متن کاملNew Classes of Algebraic Interleavers
| In this paper we present classes of algebraic interleavers that permute a sequence of bits with nearly the same statistical distribution as a randomly chosen interleaver. When these interleavers are used in turbo-coding, they perform equal to or better than the average of a set of randomly chosen interleavers. They are based on a property of quadratic congruences over the ring of integers mod...
متن کاملFurther Results on Quadratic Permutation Polynomial-Based Interleavers for Turbo Codes
An interleaver is a critical component for the channel coding performance of turbo codes. Algebraic constructions are of particular interest because they admit analytical designs and simple, practical hardware implementation. Also, the recently proposed quadratic permutation polynomial (QPP) based interleavers by Sun and Takeshita (IEEE Trans. Inf. Theory, Jan. 2005) provide excellent performan...

This paper deals with a result concerning the algebraic dual of the linear mapping defined by the multiplication of polynomial vectors by a given polynomial matrix over a commutative field
متن کاملAlgebraic Quantum Permutation Groups
We discuss some algebraic aspects of quantum permutation groups, working over arbitrary fields. If K is any characteristic zero field, we show that there exists a universal cosemisimple Hopf algebra coacting on the diagonal algebra K: this is a refinement of Wang’s universality theorem for the (compact) quantum permutation group. We also prove a structural result for Hopf algebras having a non-...
