Abstract
A system for receiving radio stations includes: at least one A/D converter in order to digitize the entire desired frequency band, for instance, an FM band, received via at least one antenna, and a demodulation unit for demodulating at least two signals of different transmitting frequencies of a radio station.
Claims21
A system for receiving radio transmissions from an FM radio station, comprising:
- at least one A/D converter to digitize an entire FM frequency band received via at least one antenna to produce a plurality of signals of different transmitting frequencies of the FM radio station;
- and
- a digital signal processing unit for subsequently:
- evaluating a reception quality of the plurality of signals of different transmitting frequencies of the FM radio station;
- selecting at least two signals of different transmitting frequencies of the FM radio station based on the evaluating;
- demodulating the at least two signals of different transmitting frequencies of the FM radio station;
- and
- combining the at least two signals of different transmitting frequencies of the FM radio station.
A method for receiving radio transmissions from an FM radio station, comprising:
- digitizing, using at least one A/D converter, an entire FM frequency band received via at least one antenna;
- subsequently, using a digital signal processing unit:
- evaluating a reception quality of a plurality of signals of different transmitting frequencies of the FM radio station;
- selecting at least two signals of different transmitting frequencies of the FM radio station based on the evaluating;
- demodulating the at least two signals of different transmitting frequencies of the FM radio station;
- and
- combining the at least two signals of different transmitting frequencies of the FM radio station.
A method for receiving radio transmissions from a radio station, the method comprising:
- digitizing, using at least one A/D converter, an entire desired frequency band received via at least one antenna;
- subsequently, using a digital signal processing unit:
- repeatedly evaluating a reception quality of each of a plurality of signals of different transmitting frequencies and selecting higher quality signals;
- demodulating at least two signals of the different transmitting frequencies of the radio station;
- combining the at least two signals;
- and
- depending on the reception quality of one of the evaluated signals, performing a switchover to another signal by cross-fading the two signals.
A non-transitory computer-readable data storage medium storing a computer program having program codes which, when executed on a computer, perform a method for receiving radio transmissions from an FM radio station, the method comprising:
- digitizing, using at least one A/D converter, an entire FM frequency band received via at least one antenna to produce a plurality of signals of different transmitting frequencies of the FM radio station;
- and
- subsequently, using a digital signal processing unit:
- evaluating a reception quality of the plurality of signals of different transmitting frequencies of the FM radio station;
- selecting at least two signals of different transmitting frequencies of the FM radio station based on the evaluating;
- demodulating the at least two signals of different transmitting frequencies of the FM radio station;
- and
- combining the at least two signals of different transmitting frequencies of the FM radio station.
A system for receiving radio transmissions from a radio station, comprising:
- at least one A/D converter configured to digitize an entire desired frequency band received via at least one antenna to produce a plurality of signals of different transmitting frequencies;
- and
- a digital signal processing unit configured to subsequently:
- repeatedly evaluate a reception quality of each of the plurality of signals of different transmitting frequencies and select higher quality signals;
- demodulate at least two signals of the different transmitting frequencies of the radio station;
- combine the at least two signals;
- and
- depending on the reception quality of one of the evaluated signals, perform a switchover to another signal by cross-fading the two signals.
