Performance conjecture. Restricting quadratic interleavers to those that admit a quadratic inverse should not impair their performance when they are applied to turbo codes.
A quasi-cyclic permutation is a permutation with cyclic algebraic structure, and a quasi-cyclic turbo code is a turbo code produced by such an interleaver. Tanner's richness conjec…
A tuned turbo code (TTC) ensemble is formed from the same structure as the asymptotically good 2-state TTCs, but with the accumulators in the outer multiperiodic convolutional code…
