MULTI-CARRIER SIGNAL DESIGNED TO REDUCE CELL INTERFERENCES IN A RADIOCOMMUNICATION NETWORK, CORRESPONDING RECEIVER, TRANSMITTER, CONSTRUCTION METHOD AND RECEPTION METHOD

摘要

The invention relates to a method of constructing a multi-carrier signal consisting of a temporal succession of symbols which are organised in successive frames. The aforementioned symbols are formed by a set of data elements which each modulate a carrier frequency of the signal. The data elements comprise: (i) reference elements whereof the value at transmission is known to at least one receiver which is intended to receive the signal; and (ii) informative data elements whereof the value at transmission is not known a priori to said receiver(s). The signal is transmitted by a first source of a radiocommunication network. According to the invention, one such construction method comprises the following steps: insertion of at least one substantially zero energy element into the above-mentioned data elements; and positioning of the substantially zero energy element(s) within the time-frequency space at one or more locations corresponding to the locations of the reference elements of at least one second multi-carrier signal which is transmitted by at least one second source of the network and which has the same structure as the first signal.
