RECEIVING APPARATUS AND RECEIVING METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18037519 titled 'RECEIVING APPARATUS AND RECEIVING METHOD
Simplified Explanation
The present invention is a receiving apparatus that receives signal light frequency-modulated by a signal obtained by adding a main signal and a control signal with a lower frequency than the main signal. It converts the signal light into an analog electric signal and acquires a code sequence corresponding to the control signal based on the analog electric signal.
- The receiving apparatus includes a reception unit that converts signal light into an analog electric signal.
- The processing unit in the apparatus acquires a code sequence corresponding to the control signal from the analog electric signal.
- The processing unit also includes a frequency offset amount acquisition unit that determines the frequency offset amount of the signal light based on the analog electric signal.
- The determination unit in the processing unit determines the code sequence corresponding to the control signal based on the acquired frequency offset amount.
Potential Applications
- This technology can be used in optical communication systems to receive and process frequency-modulated signal light.
- It can be applied in optical data transmission systems to extract control signals from the received signal light.
Problems Solved
- The receiving apparatus solves the problem of extracting control signals from frequency-modulated signal light.
- It addresses the challenge of accurately determining the code sequence corresponding to the control signal in the presence of frequency offset.
Benefits
- The receiving apparatus simplifies the process of acquiring code sequences from frequency-modulated signal light.
- It improves the accuracy of determining the code sequence by considering the frequency offset amount.
- This technology enhances the efficiency and reliability of optical communication systems.
Original Abstract Submitted
One aspect of the present invention is a receiving apparatus including a reception unit that receives signal light frequency-modulated by a signal obtained by adding a main signal and a control signal having a lower frequency than the main signal, and converts the signal light into an analog electric signal, and a processing unit that acquires a code sequence corresponding to the control signal on the basis of the analog electric signal, in which the processing unit includes a frequency offset amount acquisition unit that acquires a frequency offset amount of the signal light acquired on the basis of the analog electric signal, and a determination unit that determines the code sequence corresponding to the control signal on the basis of the frequency offset amount acquired by the frequency offset amount acquisition unit.
