METHOD AND DEVICE FOR SENDING/RECEIVING ELECTROMAGNETIC SIGNALS RECEIVED/SENT ON ONE OR MORE FIRST FREQUENCY BANDS

摘要

In order to send electromagnetic signals received on one or more first frequency bands, the method applies a transformation (59) to the signals, by performing the following actions: selecting first frequency subbands, forming a first set ({Fi,i(k}) of frequency subbands of the said first frequency band(s); using organisation rules to associate one or more second sets ( {F2,p,q}, {F2,m,n} ) of frequency subbands (F2,1,k, F2,1,2, F2,1,3, F2,1,4), forming one or more second frequency bands, with each first frequency subband (F1,1,k, F1,1,2, F1,1,3, F1,1,4) forming said first set; and using optimization rules to determine frequency translations in order to transpose the signals received in the first frequency subbands into signals sent in the second frequency band(s).
