Abstract
Method of allocating orthogonal codes in a code division multiple access mobile radio system using codes of variable length which are generated in such a way that they can be represented in the form of a tree, said method including, in response to a code allocation request, a first step of determining, in accordance with the tree capacity used, corresponding to codes already allocated, and the tree capacity required, corresponding to the code allocation requested, if such allocation is possible.
