The present invention concerns channel codes particularly well adapted to
transmission in channels in which errors tend to occur in bursts.
Moreover, the codes according to one embodiment of the invention using an
algebraic geometric curve are easy to decode and have a relatively high
minimum distance. The invention also relates to the corresponding
encoding and decoding methods, as well as the devices and apparatuses
adapted to implement those methods. Application is in particular to mass
storage, and to systems of communication by OFDM.
