SIGNAL PROCESSING METHOD AND APPARATUS, AND COHERENT RECEIVER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18071402 titled 'SIGNAL PROCESSING METHOD AND APPARATUS, AND COHERENT RECEIVER
Simplified Explanation
The patent application describes a signal processing method and apparatus for a coherent receiver. The method involves several steps including obtaining real-number signals, performing number theoretic transform (NTT) processing, clock recovery, polarization compensation, inverse number theoretic transform (INTT) processing, phase recovery, and decoding to obtain bit signals.
- The method involves obtaining P real-number signals.
- The P real-number signals are subjected to number theoretic transform (NTT) processing to obtain P transform-domain first real-number signals.
- Clock recovery is performed on the P transform-domain first real-number signals to obtain P transform-domain second real-number signals.
- Polarization compensation and inverse number theoretic transform (INTT) processing are performed on the P transform-domain second real-number signals to obtain m time-domain complex-number signals X and m time-domain complex-number signals Y.
- Phase recovery and decoding are performed on the m time-domain complex-number signals X and the m time-domain complex-number signals Y to obtain bit signals.
Potential applications of this technology:
- Coherent optical communication systems
- Digital signal processing in telecommunications
- High-speed data transmission
Problems solved by this technology:
- Efficient signal processing in coherent receivers
- Clock recovery and phase recovery in signal processing
- Compensation for polarization effects in optical communication
Benefits of this technology:
