Wavelet convolutional codes with bipartite trellises

We introduce a method novel to generate new types of time-varying convolutional codes using finite-field wavelets. These codes have a new type of trellis that we refer to as a bipartite (or k-partite) trellis. An important feature of the k-partite trellises is their reduced decoding complexity.
