Abstract
The disclosed systems and methods for processing a subcarrier-multiplexed signal comprising: i) mixing the subcarrier-multiplexed signal with a local oscillator (LO) signal; ii) extracting a respective subcarrier signal from the subcarrier-multiplexed signal; iii) sampling the respective subcarrier signal; iv) extracting timing recovery information from the respective subcarrier signal; and v) processing the respective sampled subcarrier signal to extract data from the respective sampled subcarrier signal.
Claims18
A system for processing a subcarrier-multiplexed signal comprising:
- a plurality of processors, each one of the plurality of processors comprising:
- at least one mixer configured to mix the subcarrier-multiplexed signal with a local oscillator (LO) signal generated by a LO;
- at least one filter configured to extract a respective subcarrier signal from the subcarrier-multiplexed signal;
- at least one analog-to-digital converter (ADC) configured to sample the respective subcarrier signal;
- a timing recovery module configured to extract timing recovery information from the respective subcarrier signal;
- a reference clock module configured to provide a reference clock in accordance with the timing recovery information;
- and
- a LO controller configured to control the LO to generate the LO signal in accordance with the timing recovery information and the reference clock;
- wherein each one of the plurality of processors is configured to process the respective sampled subcarrier signal to extract data from the respective sampled subcarrier signal in accordance with the LO signal.
