A method for determining a rds - round radio the shaft and the rds - receiver

摘要

A method for determining a rds - round radio shaft, wherein a from the received signal is extracted from the rds own frequency component, comprising the steps of:– Extracting a binary base band signal (bb) from the received signal, wherein the baseband signal (bb) a group (a) of phases change points (bbedge) with periodicity and a group (b) of phases change points (bbedge) comprises without periodicity,– repeated generating a first time window (clock 2) and a second time window (invclock 2), which is different to the first time window (clock2)– Determining whether a phase change point (bbedge) of the base band signal (bb) in a predetermined number of successive first time windows (clock 2) is present,– Determining whether a phase change point (bbedge) of the base band signal (bb) in a predetermined number of consecutive second time windows (invclock 2) is present and– Determining that the received signal, a rds - round radio wave is, if the determined phase change points (bbedge) of the base band signal (bb) in at least four consecutive first time windows (clock2) or, if..
