Method for determining an optimum received signal from a multi-antenna system in the event of FM co-channel reception for a reception frequency, wherein the method has the following steps: processing a first antenna signal (228, 236) to produce a first FM signal using a first processing rule and processing at least one second antenna signal (232, 240) to produce a second FM signal using a second processing rule; determining a first rating criterion for the first FM signal and a second rating criterion for the second FM signal, wherein the determined rating criterion (260, 264) is a respective piece of RDS information; selecting one of the FM signals (252, 256) as the optimum received signal for the reception frequency using the first rating criterion and the second rating criterion, wherein if only one of the FM signals (252, 256) has a piece of RDS information that corresponds to a piece of desired RDS information, the applicable FM signal (252, 256) is selected as the optimum received signal; redetermining a first rating criterion for the first FM signal and a second rating criterion for the second FM signal if an optimum received signal has not been selected in the preceding step of selection, wherein the determined rating criterion (260, 264) is a respective value of a pilot tone frequency deviation; selecting one of the FM signals (252, 256) as the optimum received signal for the reception frequency using the first rating criterion and the second rating criterion, wherein if only one of the FM signals (252, 256) has a value of a pilot tone frequency deviation that corresponds to a desired value for the pilot tone frequency deviation, the applicable FM signal (252, 256) is selected as the optimum received signal; redetermining a first rating criterion for the first FM signal and a second rating criterion for the second FM signal if an optimum received signal has not been selected in the preceding steps of selection, wherein the determined rating criterion (260, 264) is a respective piece of quality information for the FM signal; and selecting one of the FM signals (252, 256) as the optimum received signal for the reception frequency using the first rating criterion and the second rating criterion, wherein the FM signal (252, 256) having the better quality information is selected as the optimum received signal. processing a first antenna signal (228, 236) to produce a first FM signal using a first processing rule and processing at least one second antenna signal (232, 240) to produce a second FM signal using a second processing rule; determining a first rating criterion for the first FM signal and a second rating criterion for the second FM signal, wherein the determined rating criterion (260, 264) is a respective piece of RDS information; selecting one of the FM signals (252, 256) as the optimum received signal for the reception frequency using the first rating criterion and the second rating criterion, wherein if only one of the FM signals (252, 256) has a piece of RDS information that corresponds to a piece of desired RDS information, the applicable FM signal (252, 256) is selected as the optimum received signal; redetermining a first rating criterion for the first FM signal and a second rating criterion for the second FM signal if an optimum received signal has not been selected in the preceding step of selection, wherein the determined rating criterion (260, 264) is a respective value of a pilot tone frequency deviation; selecting one of the FM signals (252, 256) as the optimum received signal for the reception frequency using the first rating criterion and the second rating criterion, wherein if only one of the FM signals (252, 256) has a value of a pilot tone frequency deviation that corresponds to a desired value for the pilot tone frequency deviation, the applicable FM signal (252, 256) is selected as the optimum received signal; redetermining a first rating criterion for the first FM signal and a second rating criterion for the second FM signal if an optimum received signal has not been selected in the preceding steps of selection, wherein the determined rating criterion (260, 264) is a respective piece of quality information for the FM signal; and selecting one of the FM signals (252, 256) as the optimum received signal for the reception frequency using the first rating criterion and the second rating criterion, wherein the FM signal (252, 256) having the better quality information is selected as the optimum received signal.
