Woven convolutional codes I: Encoder properties

Höst, Stefan LU ; Johannesson, Rolf LU and Zyablov, VV (2002) In IEEE Transactions on Information Theory 48(1). p.149-161
Abstract
Encoders for convolutional codes with large free distances can be constructed by combining several less powerful convolutional encoders. This paper is devoted to constructions in which the constituent convolutional codes are woven together in a manner that resembles the structure of a fabric. The general construction is called twill and it is described together with two special cases, viz., woven convolutional encoders with outer warp and with inner warp. The woven convolutional encoders inherit many of their structural properties, such as minimality and catastrophicity, from their constituent encoders. For all three types of woven convolutional codes upper and lower bounds on their free distances as well as lower bounds on the active... (More)
