Abstract
A method for extracting a plurality of data streams from a time-frequency division multiplexed (TFDM) signal includes determining a plurality of sub-channels of the TFDM signal, where each of the plurality of sub-channels has a respective one of a plurality of frequency ranges. The method also includes down-converting, based on the plurality of frequency ranges, the TFDM signal into a plurality of down-converted signals, where each down-converted signal corresponds to a respective one of the plurality of sub-channels. The method also includes extracting the plurality of data streams from a respective one of the plurality of down-converted signals.
Claims19
A method for extracting a plurality of data streams from a time-frequency division multiplexed (TFDM) signal, comprising:
- determining a plurality of sub-channels of the TFDM signal, each of the plurality of sub-channels having a respective one of a plurality of frequency ranges;
- down-converting, based on the plurality of frequency ranges, the TFDM signal into a plurality of down-converted signals, each down-converted signal corresponding to a respective one of the plurality of sub-channels;
- and
- extracting the plurality of data streams from a respective one of the plurality of down-converted signals.
A burst receiver, comprising:
- a coherent receiver that receives a time-frequency division multiplexed (TFDM) signal;
- a processor communicatively coupled to the coherent receiver;
- and
- a memory storing computer-readable instructions that, when executed by the processor, cause the processor to extract a plurality of data streams from the TFDM signal by:
- determining a plurality of sub-channels of the TFDM signal, each of the plurality of sub-channels having a respective one of a plurality of frequency ranges;
- down-converting, based on the plurality of frequency ranges, the TFDM signal into a plurality of down-converted signals, each down-converted signal corresponding to a respective one of the plurality of sub-channels;
- and
- extracting the plurality of data streams from a respective one of the plurality of down-converted signals.
