PCA-based Dispersed Fringe Co-phasing Method
Frontiers in Optics + Laser Science 2023 (FiO, LS), 2023Dispersed fringe sensing (DFS) is a promising co-phasing approach for a segmented telescope. We proposed a novel piston error extraction method based on principal component analysis (PCA) technology and demonstrated its performance with simulations.

Co-phase power supply system for HSR
2014 International Power Electronics Conference (IPEC-Hiroshima 2014 - ECCE ASIA), 2014Poor power quality and phase splitting are the main issues in electric railway. Co-phase traction power supply system is adopted in electrified railway for active power balance, reactive power compensation and harmonic filter. The research development and application of co-phase traction power supply system in China are depicted detailed in this paper.

Co-phase transmission diversity for distributed antenna
2005 IEEE Antennas and Propagation Society International Symposium, 2005Due to the single element nature of the antenna at the mobile station, the traditional downlink diversity schemes of distributed antennas, such as simulcast or multipath antenna diversity, cannot exploit the advantage of distributed antennas as much as the uplink.

Note on the Hf-Co phase diagram
Journal of the Less Common Metals, 1978Abstract The Co-rich part of the Hf-Co phase diagram has been re-investigated by X-ray diffraction, thermal analysis and metallography. The compound HfCo6 reported in the literature proved to be non-existent. Three new compounds were found: Hf2Co7, Hf6Co23 and HfCo7. The latter two compounds give rise to a eutectoid decomposition close to 1000 °C.

Passive Co-Phasing of Fiber Lasers for Coherent Combining
Fiber and Integrated Optics, 2008A solution to power rising of fiber lasers is the coherent combining of radiations from a parallel arrangement of amplifiers. We have experimentally investigated two passive techniques where an intracavity spectral or spatial filtering is implemented to phase-lock the elementary beams.

Multi-stream distributed co-phasing: Design and analysis
2016 IEEE 17th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2016In this paper, we develop and analyze a distributed co-phasing technique for physical layer fusion of common data across a wireless sensor network using multi stream communication, when the fusion center (FC) is equipped with multiple receive antennas.
