Abstract

See full text

The method pertains to wireless transmission in the common-wave operation. For the operation of common-wave networks, it is required that the modulation contents of the transmission frequencies (1 . . . m) transmitted by the individual transmitting stations are identical. However, in order to enable a station or regional identification, one or more regionally differing additional carrier frequencies (n-3 . . . n) are transmitted, whose reception permits the selection of specific regionally related news or messages in the receiver. The demand of additional carrier frequencies may be reduced to four individual frequencies or frequency groups, if these additional carriers are modulated.
