| 摘要 |
The invention concerns a multicarrier signal consisting of a temporal suc cession of symbols formed by a set of data elements, each of said data eleme nts modulating a carrier frequency of said signal, the data elements compris ing reference elements called pilots (20) whereof the value in transmission is known to at least one receiver designed to receive said signal and inform ative data elements (21-28), whereof the value in transmission is not known a priori to the or said receiver(s), one of said carrier frequencies modulat ed, at a given time, by one of said data elements, being called carrier. The invention is characterised in that it at least one constraint is imposed on the value of at least one of said informative data elements, so as to reduc e, in reception, at least one term of interference affecting at least one of said pilots.
