Abstract

The data source (for long-wave single-sideband transmission of the RDS signal (SSB-RDS))is an RDS coder capable of QDSB modulation with or without the carrier frequency. The RDS-SSB signal with vestigial carrier is produced by the filter method and converted to the transmission frequency by mixing. The road traffic information carrier which can be fed into the RDS coder can thus be used as the vestigial carrier. A known all-band receiver with synchronous demodulator is used for receiving the SSB-RDS signal. Further processing of the RDS baseband (biphase signal) is a straightforward matter.
