DISTRIBUTED PILOT MULTICARRIER SIGNAL DESIGNED TO LIMIT INTERFERENCE AFFECTING SAID PILOTS

摘要

The invention concerns a multicarrier signal consisting of a temporal succession of symbols formed by a set of data elements, each of said data elements modulating a carrier frequency of said signal, the data elements comprising reference elements called pilots (20) whereof the value in transmission is known to at least one receiver designed to receive said signal and informative 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 modulated, 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 reduce, in reception, at least one term of interference affecting at least one of said pilots.
