Abstract
In this paper, permutor design aspects for woven convolutional encoders (WCEs) with outer warp (OW) are discussed. We show how the minimum distance of the overall code can be increased by considering all warp permutors together. A bound on the minimum distance of a code generated by a WCE with OW and designed permutors is presented that considerably exceeds those with known designs.
