Electromagnetic Receivers TRIZ Cases
- Coherent Optical Receiver Skew Compensation via Digital Signal Processing
A coherent optical receiver applies opposite skew amounts to digital signals before fast Fourier transform processing.
- Differential Differencing Transimpedance Amplifier for Coherent Optical Receivers
A differential differencing transimpedance amplifier segments optical signals into independent paths to enhance signal-to-noise ratio.
- Coherent Optical Receiver Carrier Phase Estimation
A coherent optical receiver adjusts carrier phase estimator filter parameters based on measured spectral structure and bandwidth information.
- Data Receiving Apparatus for Multi-Rate Optical Signals
A data receiving apparatus routes signals via a cross point switch to dedicated units.
- Optical Network Element Local Oscillator Frequency Detection
Detect local oscillator spectral position via pattern matching to resolve measurement precision versus device complexity trade-offs in optical networks.
