Abstract
The invention relates to the transmission and reception of non-binary error correcting code words. The transmission method includes a first modulation (56) which implements a set of q sequences comprising q−1 sequences of q−1 chips, each sequence being obtained by circular shifting of a basic pseudo-random sequence, and a partially invariant sequence, invariant to a predetermined subset of circular shifts. The first modulation (56) further implements an association between each code word symbol and a sequence of the set of sequences wherein said finite field GFq has a non-zero primitive element, the symbol zero being associated with said partially invariant sequence and a symbol equal to a power j of the primitive element, j being an integer comprised between 0 and q−2, being associated with a pseudo-random sequence determined by j circular shifts of the basic pseudo-random sequence.
