Method of assigning one or more spreading sequences to users of a multi carrier transmission network

摘要

A method of assigning one or more spreading sequences to users of a Multi Carrier transmission network, each element of the spreading sequence being, at a transmitter of the network, multiplied by a data item to be transmitted and then transmitted on a corresponding sub-carrier. The method includes obtaining spatial information for each user of the Multi-Carrier transmission network, putting the users in order according to their spatial information, and assigning at least a spreading sequence among a group of ordered spreading sequences to each user according to its order.
