Patent ID: 7639986

Claim:
Method for automatic planning of transmission time delays of different radio transmitters ( 4 ) generating radio cells with one single frequency to form a digital television broadcasting wireless network (N) that is time and frequency synchronous, implemented via a computing system ( 1 ) comprising memorization means ( 12 ) to store data related to the network (N) including data ( 3 ) representing geographical areas divided into a plurality of dots or pixels ( 301 , 302 , 303 ) in accordance with the divisions of said network (N) and containing the position of the radio transmitters ( 4 ), population data corresponding to the network divisions, data ( 31 ) specifying a transmission level of the transmitters and a sensitivity threshold level of radio reception by terminals of the cell ( 1 ), data ( 32 ) representing a radio propagation attenuation law and data representing a time period of guard intervals (GI) inserted between data frames, the system ( 1 ) also comprising a calculation module ( 11 ) and means for parametering a plurality of radio transmitters ( 4 ), the method comprising for each radio transmitter ( 4 ) an initiation step to initiate a transmission at a determined instant, characterized in that it comprises a processing step ( 500 ) to process data related to the network (N) using the calculation module ( 11 ) to calculate data representing figures of populations located in zones (Br) of disturbing interference and a step ( 54 ) to adjust said initiation step performed for each radio transmitter ( 4 ) using a transmission delay varying between 0 and a non-zero value less than 1 ms with memorization for each radio transmitter ( 4 ) of the delay used, the adjustment step ( 54 ) being follower by a reiteration of processing step ( 500 ) to re-estimate figures of populations located in zones of disturbing interference, processing step ( 500 ) being reiterated with a number of iterations parametered using the configuration means ( 13 ) of the system ( 1 ), the adjustment step being finalized after the iterations by using a memorized combination of delays for each transmitter in the set of transmitters ( 4 ) allowing a minimum figure to be reached of said estimated populations in zones (Br) of disturbing interference.
