Abstract
A radio communication emitter includes at least two antennas for emitting a signal including encoded bits that are converted into symbols distributed on subcarriers and in time intervals. The emitter includes a signal divider for distributing the set of the signal symbols into as many disjoined subsets of signal symbols as the antennas that the emitter comprises. Each subset is dedicated to one of the antennas. The union of the subsets is the set of the signal symbols. Symbols are distributed in at least two subsets for at least one time interval or for at least one subcarrier of the signal. The antennas synchronously emit the symbol subsets. The symbol subsets can comprise a substantially identical number of symbols to reduce a deviation between the power peaks and the average power of the signal emitted by each antenna.
