Receiver design for optical inter-satellite links based on digital signal processing
2016 18th International Conference on Transparent Optical Networks (ICTON), 2016We present a comparison of homodyne and intradyne detection schemes for high-order modulation formats in optical inter-satellite communication systems. The homodyne detection based on optical PLL techniques is numerically investigated for BPSK and QPSK transmission.

All-digital Compensation of Doppler Shift in LEO-LEO Optical Inter-satellite Links
Optica Advanced Photonics Congress 2022, 2022We evaluate the all-digital Doppler shift compensation in LEO-LEO coherent optical inter-satellite links. Doppler shift figures are assessed by the simulation of commercial orbits. The results indicate a two-stage compensation method as a viable solution.
