The system for automatic planning of delays in a network (N) of SFN type comprises: means initiating an OFDM transmission for each radio transmitter ( 4 ), inter-symbol delays being provided; a calculation module processing network data and determining figures of populations located in zones with interference; control means and initiation means to delay transmission at each transmitter, with a delay varying between 0 and 1 ms; delay adjustment means linked to the control means for combinations of delays for all transmitters. The module ( 11 ) recalculates the figures of populations located in interference zones for successive combinations of delays, and configuration means ( 13 ) of the system provide the number of permitted iterations. The optimal combination is obtained when said estimated population figures are minimum.
