Abstract: The invention relates to a radio broadcast method for a multi-carrier digital signal (51), occupying a first frequency band adjacent to at least one second frequency band, each allocated for a second signal (52, 53), said, or at least one of said second signals being an analogue radio broadcast signal. A pre-filtering (54, 55) is applied to the first signal before the transmission thereof, such as to attenuate the power of said first signal at least in a first portion of said first frequency band, adjacent to the second frequency band(s).

Abstract: The invention relates to a method of synchronizing a multicarrier signal received by a receiver, said multicarrier signal comprising, on transmission, a set of data elements and a set of reference elements called pilots, the value and the location of said pilots on transmission being known to said receiver. According to the invention, such a method comprises the following steps: obtaining a sequence of a reference signal, termed the reference sequence, representative of the location of at least one of said pilots of said multicarrier signal; obtaining a sequence from said signal received, termed the determination sequence; determining, for said determination sequence, a synchronization peak, on the basis of a correlation between said reference sequence and said determination sequence; synchronizing at least one sequence that temporally follows said determination sequence, on the basis of said synchronization peak.
