Complex interaction among optical signal distortions, analog component characteristics, and digital signal processing algorithms can give rise to significant performance degradation in the coherent system performance. Two topics are introduced as examples of such phenomena.
We propose a digital clock recovery algorithm and demonstrate its tolerance to at least 5 GHz laser frequency mismatch in a 43 Gb/s DP-RZ-QPSK receiver after 1200 km transmission.
A novel frequency offset estimator is proposed and implemented in a 1 Gbit/s real-time coherent receiver to demonstrate all-digital frequency offset compensation up to plusmn0.4 symbol rate.
Hybrid simulation was performed to analyze the response of the real-time reflection-type radio frequency single-electron transistor (RF-SET) measurement system. A compact and physically-based analytical SET model, which was validated with a Monte Carlo simulator, was used to simulate the SET characteristics, while SPICE equivalent circuits were implemented to simulate all other components of the RF-SET...
