OPTICAL SIGNAL STATE ESTIMATION APPARATUS, OPTICAL SIGNAL STATE ESTIMATION METHOD, AND NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18225942 titled 'OPTICAL SIGNAL STATE ESTIMATION APPARATUS, OPTICAL SIGNAL STATE ESTIMATION METHOD, AND NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM
Simplified Explanation
The patent application describes an optical signal state estimation apparatus that includes a processor. The processor performs three main processes: acquisition, generation, and estimation.
- Acquisition process: The processor acquires a constellation of an optical signal. A constellation represents the signal points in the optical signal.
- Generation process: The processor generates time series data by arranging pieces of histogram information in a time series. The histogram information is obtained by counting the number of signal points in the constellation. The signal points are included in grids obtained by dividing the in-phase component direction and the quadrature component direction into a specific number of rows and columns.
- Estimation process: The processor estimates the state of the optical signal by inputting the time series data to a learned model.
Potential applications of this technology:
- Optical communication systems: The technology can be used to estimate the state of optical signals in communication systems, allowing for improved signal processing and optimization.
- Optical signal analysis: The apparatus can be utilized in analyzing optical signals in various fields, such as scientific research, medical imaging, and industrial inspections.
Problems solved by this technology:
- Signal state estimation: The technology provides a method for accurately estimating the state of optical signals, which can be challenging due to noise, interference, and complex signal characteristics.
- Data processing efficiency: The generation process organizes the histogram information into time series data, enabling efficient processing and analysis of the optical signal state.
Benefits of this technology:
- Improved signal processing: Accurate estimation of the optical signal state allows for enhanced signal processing techniques, leading to improved performance and reliability in optical communication systems.
- Enhanced data analysis: The time series data generated by the apparatus provides valuable insights into the characteristics and behavior of optical signals, enabling more effective data analysis and interpretation.
