Abstract :
A low-rate turbo coding scheme based on superorthogonal convolutional encoders is examined. We analyze the asymptotic performance that can be achieved when both the code length and the number of iterations tend to infinity and present a bound on the iterative limit of this superorthogonal turbo code construction. Simulations of the codes with large permutors (interleavers) confirm the results of the asymptotic analysis.
