Encoding and decoding trellis codes with trellis sections based on block codes with good constraint properties

摘要

The process involves using two distinct sections of a predetermined elementary code and associating a vector of initial state and an arrival vector according to branches of a vector label. A code word is defined such that two sections of the elementary code are distinct even when order and/or role of the vectors of the vector label of the branches are modified. An independent claim is also included for an error correcting encoding device.
