On Inverses for Quadratic Permutation Polynomials over Integer Rings
Jonghoon Ryu, Oscar Y. Takeshita
Quadratic permutation polynomial interleavers over integer rings have recently received attention in practical turbo coding systems from deep space applications to mobile communica…
Permutation Polynomial Interleavers: An Algebraic-Geometric Perspective
Oscar Y. Takeshita
An interleaver is a critical component for the channel coding performance of turbo codes. Algebraic constructions are important because they admit analytical designs and simple, pr…
On Quadratic Inverses for Quadratic Permutation Polynomials over Integer Rings
Jonghoon Ryu, Oscar Y. Takeshita
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 a…
A New Construction for LDPC Codes using Permutation Polynomials over Integer Rings
Oscar Y. Takeshita
A new construction is proposed for low density parity check (LDPC) codes using quadratic permutation polynomials over finite integer rings. The associated graphs for the new codes…
On Maximum Contention-Free Interleavers and Permutation Polynomials over Integer Rings
Oscar Y. Takeshita
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 a…
