Apparatus and method for multi-signal interference-avoiding data transmission

摘要

The present technology provides an apparatus and a method for transmitting data via two or more FM signals in an interference avoiding manner. The apparatus comprises at least two FM transmitters. Each FM transmitter is configured to transmit a FM signal on a particular FM channel characterized by a certain carrier frequency that includes data and optionally one or more corresponding alternative frequencies (AFs). The apparatus further includes at least two receivers for receiving incoming electromagnetic radiation (EMR). At least one of the receivers is configured to receive incoming EMR associated with at least one of the FM channels, and another is configured to receive incoming EMR at least at frequencies outside of the FM channels. The controller is configured to separately control activation and deactivation of the FM transmitters and determine the carrier frequencies and the one or more AFs based upon incoming EMR.

主权项

1. An apparatus for transmitting data via frequency modulation (FM) of electromagnetic radiation; the apparatus comprising:
a. a first FM transmitter configured to transmit a first FM signal on a first FM channel characterized by a first carrier frequency, the first FM signal including the data and optionally an indication of one or more first alternative frequencies (AFs); b. a second FM transmitter configured to transmit a second FM signal on a second FM channel characterized by a second carrier frequency, the second FM signal including the data and optionally an indication of one or more second AFs; c. a first receiver configured to receive incoming electromagnetic radiation associated with at least one of the first FM channel and the second FM channel; d. a second receiver configured to receive incoming electromagnetic radiation at least at one or more frequencies outside of the first FM channel and the second FM channel; and e. a controller operatively connected with the first FM transmitter, the second FM transmitter, the first receiver and the second receiver, the controller configured to determine the first carrier frequency and the second carrier frequency based upon incoming electromagnetic radiation; the controller further configured to separately control activation and deactivation of the first FM transmitter and the second FM transmitter.
