摘要
The use of the RDS as an additional data channel is so far limited to VHF-FM transmitter. The invention solves the technical problem of the use even in AM stations in the area LMK; The data to be transmitted are fed as an output signal of an RDS coder using an HP / TP filter and used as a modulation of a SSB modulator, and the resulting transmit band is selectively irradiated as lower or upper sideband of a radio transmitter with carrier suppression, and the unused sideband that of is that is was moderately used for the existing audio modulation of the transmitter.; Transmission end, the carrier power is saved. In addition, the broadcasting within the coordinated bandwidth of an audio transmitter with single-sideband modulation in the other sideband can be done so that the existing frequency resource is used and not have their own broadcasting infrastructure for the application of the process is required.
