Abstract

Egy rádiós adatrendszer (RDS) jelének hősszúhűllámú egyőldalsávős(SSB-RDS) átvitelénél az adatfőrrás egy RDS-kódőló, amelyvivőfrekvenciás vagy vivőfrekvencia nélküli QDSB-mődűlációt végez. Amaradékvivővel rendelkező RDS-SSB jelet szűrőmódszerrel állítják elő,és az adási frekvenciára keverik. Maradékvivőként felhasználható azRDS-kódőlón bekapcsőlható ARI-vivő. Az SSB-RDS jel vételére szinkrőndemődűlátőrt tartalmazó többsávős vevőt alkalmaznak. Az RDS-alapsáv(kétfázisú jel) tővábbi feldőlgőzása nem őkőz nehézséget. ŕIn SSB-RDS (SSB-RDS) transmission of a Radio Data System (RDS) signal, the data source is an RDS encoder that performs QDSB modulation with or without a carrier frequency. An RDS-SSB signal with a residual carrier is produced by a filter method and mixed to the broadcast frequency. The ARI carrier that can be captured on the RDS code can be used as a residual carrier. To receive the SSB-RDS signal, a multi-band receiver with a synchronous demodulation detector is used. Increasing the RDS baseband (two-phase signal) further is not a problem. ŕ
