ABSTRACT:
A method of constructing a spreading code associated with one user of a direct sequence code division multiple access digital transmission system includes at least one stage of concatenating a plurality of different sub-codes. Specifically, the spreading code is constructed by concatenating at least two different, in particular, cyclically different, basic sub-codes belonging to the same family of basic sub-codes, and at least one secondary sub-code obtained by circular permutation of one of the basic sub-codes. The constructed spreading code is then designated as being associated with the one user.
