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).
