Abstract
A method is provided, which comprises: receiving a radio frequency signal; generating a first radio signal by demodulating and decoding the received radio frequency signal; detecting if a data embedding mode is used; extracting a first data signal from the first radio signal in response to the data embedding mode as being detected; and outputting the processed first radio signal after extraction.
Claims20
A method, comprising:
- receiving a radio frequency signal;
- generating a first radio signal by demodulating and decoding the received radio frequency signal;
- detecting if a data embedding mode is used;
- extracting a first data signal from the first radio signal in response to the data embedding mode as being detected;
- and
- outputting the processed first radio signal after extraction.
3 more elements
A transmitter, comprising:
- a first encoder, configured to generate an audio signal;
- a second encoder, configured to generate a data signal;
- a controller, configured to determine a data embedding mode and parameters associated therewith for the audio signal and the data signal;
- and
- a signal combiner, configured to generate a data-embedding audio signal by embedding the data signal into the audio signal in response to the controller.
2 more elements
A receiver, comprising:
- a demodulation module, configured to generate a first audio signal from a radio frequency signal;
- a controller, configured to detect a data embedding mode and parameters associated thereto for the first audio signal;
- and
- a signal extractor, configured to extract a data signal from the first audio signal based on the data embedding mode and the parameters.
