Method of dynamically assigning spreading sequences to users of a multi carrier transmission network |
摘要 |
The present invention concerns a method of dynamically assigning spreading sequences of a group of spreading sequences to users of a Multi-Carrier transmission network and/or to at least a common signal for a plurality of users of the Multi-Carrier transmission network, each element of the said spreading sequences being, at a transmitter of the said network, multiplied by data items to be transmitted and then transmitted on a corresponding sub-carrier, characterised in that the spreading sequences are put in a natural order in the group of spreading sequences and the method comprises the step of dynamically assigning the spreading sequences of the group of spreading sequences according to their order in the group of spreading sequences to users of the Multi-Carrier transmission network and/or to at least a common signal to a plurality of users of the Multi-Carrier transmission network. <IMAGE>
