Moreira, J. Castiñeira; and Petruzzi, D. M. and Liberatori, M. C. and Honary, B. (2006) Trellis-hopping Turbo Coding. IEE Proceedings - Communications, 153 (6). pp. 966-975. ISSN 1350-2425Full text not available from this repository.
We present a turbo coding scheme whose constituent codes are designed using convolutional encoders with time-varying coefficients. These encoders are finite state sequence machines that operate over the Galois field GF(q). The scheme includes an encryption polynomial whose coefficients are changed periodically by means of a user key. The trellis coding procedure thus hops from one trellis to another, following a random sequence taken over a set of subtrellises which correspond to different convolutional encoders. The proposed scheme is introduced as a turbo code with encryption properties, and is presented in two forms, the systematic and the nonsystematic schemes.
