Abstract

This article presents a simple turbo coding technique to improve the error performance of a convolutional rate-1/3 turbo code by shaping its weight spectrum closer to the binomial weight distribution of a random code. This technique can be applied to both symmetric and asymmetric rate 1/3 turbo codes to achieve additional coding gain
