SYSTEM AND METHOD OF USING RADIO ALTIMETER FREQUENCY SPECTRUM FOR WIRELESS SIGNALS |
| 摘要 |
An avionics system comprises a plurality of avionics components; at least one OFDM transmitter coupled to a respective one or more of the plurality of avionics components and configured to transmit a wireless OFDM signal comprising a plurality of sub-bands; at least one OFDM receiver coupled to a respective one or more of the plurality of avionics components and configured to receive the wireless OFDM signal transmitted by the OFDM transmitter; and a radio altimeter configured to transmit a signal tone that sweeps a frequency spectrum allocated to the radio altimeter at a predefined rate and periodicity. The at least one OFDM transmitter is configured to transmit the wireless OFDM signal in the frequency spectrum allocated to the radio altimeter and to sequentially turn off respective subsets of the plurality of sub-bands in synchronization with the predefined rate and periodicity of the signal tone frequency sweep. |

1. An avionics system comprising:
a plurality of avionics components; at least one orthogonal frequency division multiplex (OFDM) transmitter coupled to a respective one or more of the plurality of avionics components and configured to transmit a wireless OFDM signal comprising a plurality of sub-bands; at least one OFDM receiver coupled to a respective one or more of the plurality of avionics components and configured to receive the wireless OFDM signal transmitted by the OFDM transmitter; and a radio altimeter configured to transmit a signal tone that sweeps a frequency spectrum allocated to the radio altimeter at a predefined rate and periodicity; wherein the at least one OFDM transmitter is configured to transmit the wireless OFDM signal in the frequency spectrum allocated to the radio altimeter; wherein the at least one OFDM transmitter is configured to sequentially turn off respective subsets of the plurality of sub-bands in synchronization with the predefined rate and periodicity of the signal tone frequency sweep. |
