1. A method of using one or more transmitters and/or one or more parameters associated with a transmitter by using a reception station having a device suitable for measuring over time a set of K parameters dependent on the transmitters associated with vectors {circumflex over (η)} k representative of the transmitters for 1≦k≦K comprising the steps of: extracting the parameter or parameters consisting in grouping together by transmitter the parameters which are associated therewith by means of a technique of independent component analysis.
