Abstract
In this article, we will study a class of concatenated coding communications systems that is built from convolutional codes and interleavers. These systems include as special cases both the classical turbo codes [1,2] and the serial concatenation of convolutional codes [4]. Our main results are a method for computing a conjectured interleaving gain exponent and for optimizing the effective free distance, d2. We include proofs of theorems about d2 that were stated without proof in [6].
